+## 1.39.0 - 2025-08-24
+- Various bug fixes
+- Add `net/socket`
+- Add support for illumos OS
+- Raise helpful errors for incorrect arguments to `import`.
+- Allow configuring `JANET_THREAD_LOCAL` during builds to allow multi-threading on unknown compilers.

+- Calling `ev/cancel` on a fiber waiting on `ev/gather` will correctly
+  cancel the child fibers.
+- Add `(sandbox ...)` function to core for permission based security. Also add `janet_sandbox` to C API.
+  The sandbox allows limiting access to the file system, network, ffi, and OS resources at runtime.

+- Add the `u` format specifier to printf family functions.
+- Allow printing 64 integer types in `printf` and `string/format` family functions.

+- Add experimental `ffi/` module for interfacing with dynamic libraries and raw function pointers. Only available
+  on 64 bit linux, mac, and bsd systems.

+- The `flycheck` function no longer pollutes the module/cache
+- Fix quasiquote bug in compiler
+- Disallow use of `cancel` and `resume` on fibers scheduled or created with `ev/go`, as well as the root

+  linting thresholds are as follows:
+    - :none - will never be trigger.
+    - :relaxed - will only trigger on `:relaxed` lints.
+    - :normal - will trigger on `:relaxed` and `:normal` lints.
+    - :strict - will trigger on `:strict`, `:normal`, and `:relaxed` lints. This will catch the most issues
+      but can be distracting.
+
+## 1.16.0 - 2021-05-30

+- Add `flycheck` function to core.
+- Make `backmatch` and `backref` more expressive in pegs.
+- Fix buggy `string/split`.
+- Add `fiber/last-value` to get the value that was last yielded, errored, or signaled
+  by a fiber.
+- Remove `:generate` verb from `loop` macros. Instead, use the `:in` verb
+  which will now work on fibers as well as other data structures.
+- Define `next`, `get`, and `in` for fibers. This lets
+  `each`, `map`, and similar iteration macros can now iterate over fibers.
+- Remove macro `eachy`, which can be replaced by `each`.
+- Add `dflt` argument to find-index.
+- Deprecate `file/popen` in favor of `os/spawn`.
+- Add `:all` keyword to `ev/read` and `net/read` to make them more like `file/read`. However, we
+  do not provide any `:line` option as that requires buffering.
+- Change repl behavior to make Ctrl-C raise SIGINT on posix. The old behavior for Ctrl-C,
+  to clear the current line buffer, has been moved to Ctrl-Q.
+- Importing modules that start with `/` is now the only way to import from project root.
+  Before, this would import from / on disk. Previous imports that did not start with `.` or `/`
+  are now unambiguously importing from the syspath, instead of checking both the syspath and
+  the project root. This is backwards incompatible and dependencies should be updated for this.
+- Change hash function for numbers.
+- Improve error handling of `dofile`.
+- Bug fixes in networking and subprocess code.
+- Use markdown formatting in more places for docstrings.
+
+## 1.13.1 - 2020-12-13

+  in the prototype table to tag the output.
+- `match` macro implementation changed to be tail recursive.
+- Adds a :preload loader which allows one to manually put things into `module/cache`.
+- Add `buffer/push` function.
+- Backtick delimited strings and buffers are now reindented based on the column of the
+  opening delimiter. Whitespace in columns to the left of the starting column is ignored unless
+  there are non-space/non-newline characters in that region, in which case the old behavior is preserved.
+- Argument to `(error)` combinator in PEGs is now optional.
+- Add `(line)` and `(column)` combinators to PEGs to capture source line and column.
+  This should make error reporting a bit easier.
+- Add `merge-module` to core.
+- During installation and release, merge janetconf.h into janet.h for easier install.
+- Add `upscope` special form.
+- `os/execute` and `os/spawn` can take streams for redirecting IO.

+- Add `os/open` if ev is enabled.
+- Add `os/pipe` if ev is enabled.

+- Add integer parsing forms to pegs. This makes parsing many binary protocols easier.
+- Lots of updates to networking code - now can use epoll (or poll) on linux and IOCP on windows.
+- Add `ev/` module. This exposes a fiber scheduler, queues, timeouts, and other functionality to users
+  for single threaded cooperative scheduling and asynchronous IO.
+- Add `net/accept-loop` and `net/listen`. These functions break down `net/server` into it's essential parts
+  and are more flexible. They also allow further improvements to these utility functions.
+- Various small bug fixes.
+

+
+## 1.6.0 - 2019-12-22

+- Add a number of new math functions.
+- Improve debugger experience and capabilities. See examples/debugger.janet
+  for what an interactive debugger could look like.
+- Add `debug/step` (janet\_step in the C API) for single stepping Janet bytecode.
+- The built in repl now can enter the debugger on any signal (errors, yields,
+  user signals, and debug signals). To enable this, type (setdyn :debug true)
+  in the repl environment.
+- When exiting the debugger, the fiber being debugged is resumed with the exit value
+  of the debug session (the value returned by `(quit return-value)`, or nil if user typed Ctrl-D).
+- `(quit)` can take an optional argument that is the return value. If a module
+  contains `(quit some-value)`, the value of that module returned to `(require "somemod")`
+  is the return value. This lets module writers completely customize a module without writing
+  a loader.
+- Add nested quasiquotation.
+- Add `os/cryptorand`
+- Add `prinf` and `eprinf` to be have like `printf` and `eprintf`. The latter two functions

+- Fix bug with `jpm` on windows.
+- Fix `update` return value.
+
+## 1.5.0 - 2019-11-10
+- `os/date` now defaults to UTC.
+- Add `--test` flag to jpm to test libraries on installation.
+- Add `math/rng`, `math/rng-int`, and `math/rng-uniform`.
+- Add `in` function to index in a stricter manner. Conversely, `get` will
+  now not throw errors on bad keys.
+- Indexed types and byte sequences will now error when indexed out of range or
+  with bad keys.
+- Add rng functions to Janet. This also replaces the RNG behind `math/random`
+  and `math/seedrandom` with a consistent, platform independent RNG.
+- Add `with-vars` macro.
+- Add the `quickbin` command to jpm.
+- Create shell.c when making the amalgamated source. This can be compiled with
+  janet.c to make the janet interpreter.
+- Add `cli-main` function to the core, which invokes Janet's CLI interface.
+  This basically moves what was init.janet into boot.janet.
+- Improve flychecking, and fix flychecking bugs introduced in 1.4.0.
+- Add `prin`, `eprint`, `eprintf` and `eprin` functions. The
+  functions prefix with e print to `(dyn :err stderr)`
+- Print family of functions can now also print to buffers
+  (before, they could only print to files.) Output can also
+  be completely disabled with `(setdyn :out false)`.
+- `printf` is now a c function for optimizations in the case
+  of printing to buffers.
+
+## 1.4.0 - 2019-10-14
+- Add `quit` function to exit from a repl, but not always exit the entire
+  application.
+- Add `update-pkgs` to jpm.
+- Integrate jpm with https://github.com/janet-lang/pkgs.git. jpm can now
+  install packages based on their short names in the package listing, which
+  can be customized via an env variable.
+- Add `varfn` macro
+- Add compile time arity checking when function in function call is known.
+- Added `slice` to the core library.
+- The `*/slice` family of functions now can take nil as start or end to get
+  the same behavior as the defaults (0 and -1) for those parameters.
+- `string/` functions that take a pattern to search for will throw an error
+  when receiving the empty string.
+- Replace (start:end) style stacktrace source position information with
+  line, column. This should be more readable for humans. Also, range information
+  can be recovered by re-parsing source.
+
+## 1.3.1 - 2019-09-21
+- Fix some linking issues when creating executables with native dependencies.
+- jpm now runs each test script in a new interpreter.
+- Fix an issue that prevent some valid programs from compiling.
+- Add `mean` to core.
+- Abstract types that implement the `:+`, `:-`, `:*`, `:/`, `:>`, `:==`, `:<`,
+  `:<=`, and `:>=` methods will work with the corresponding built-in
+  arithmetic functions. This means built-in integer types can now be used as
+  normal number values in many contexts.
+- Allow (length x) on typed arrays an other abstract types that implement
+  the :length method.
+
+## 1.3.0 - 2019-09-05
+- Add `get-in`, `put-in`, `update-in`, and `freeze` to core.
+- Add `jpm run rule` and `jpm rules` to jpm to improve utility and discoverability of jpm.
+- Remove `cook` module and move `path` module to https://github.com/janet-lang/path.git.
+  The functionality in `cook` is now bundled directly in the `jpm` script.
+- Add `buffer/format` and `string/format` format flags `Q` and `q` to print colored and
+  non-colored single-line values, similar to `P` and `p`.
+- Change default repl to print long sequences on one line and color stacktraces if color is enabled.
+- Add `backmatch` pattern for PEGs.
+- jpm detects if not in a Developer Command prompt on windows for a better error message.
+- jpm install git submodules in dependencies
+- Change default fiber stack limit to the maximum value of a 32 bit signed integer.
+- Some bug fixes with `jpm`

+- Add color to stacktraces via `(dyn :err-color)`
+
+## 1.2.0 - 2019-08-08
+- Add `take` and `drop` functions that are easier to use compared to the
+  existing slice functions.
+- Add optional default value to `get`.
+- Add function literal short-hand via `|` reader macro, which maps to the
+  `short-fn` macro.
+- Add `int?` and `nat?` functions to the core.
+- Add `(dyn :executable)` at top level to get what used to be
+  `(process/args 0)`.
+- Add `:linux` to platforms returned by `(os/which)`.
+- Update jpm to build standalone executables. Use `declare-executable` for this.
+- Add `use` macro.
+- Remove `process/args` in favor of `(dyn :args)`.
+- Fix bug with Nanbox implementation allowing users to created
+  custom values of any type with typed array and marshal modules, which
+  was unsafe.
+- Add `janet_wrap_number_safe` to API, for converting numbers to Janets
+  where the number could be any 64 bit, user provided bit pattern. Certain
+  NaN values (which a machine will never generate as a result of a floating
+  point operation) are guarded against and converted to a default NaN value.
+
+## 1.1.0 - 2019-07-08
+- Change semantics of `-l` flag to be import rather than dofile.
+- Fix compiler regression in top level defs with destructuring.
+- Add `table/clone`.
+- Improve `jpm` tool with git and dependency capabilities, as well as better
+  module uninstalls.
+
+## 1.0.0 - 2019-07-01
+- Add `with` macro for resource handling.
+- Add `propagate` function so we can "rethrow" signals after they are
+  intercepted. This makes signals even more flexible.
+- Add `JANET_NO_DOCSTRINGS` and `JANET_NO_SOURCEMAPS` defines in janetconf.h
+  for shrinking binary size.
+  This seems to save about 50kB in most builds, so it's not usually worth it.
+- Update module system to allow relative imports. The `:cur:` pattern
+  in `module/expand-path` will expand to the directory part of the current file, or
+  whatever the value of `(dyn :current-file)` is. The `:dir:` pattern gets
+  the directory part of the input path name.
+- Remove `:native:` pattern in `module/paths`.
+- Add `module/expand-path`
+- Remove `module/*syspath*` and `module/*headerpath*` in favor of dynamic
+  bindings `:syspath` and `:headerpath`.

+- Add optional argument to `parser/where` to set parser byte index.
+- Add optional `env` argument to `all-bindings` and `all-dynamics`.
+- Add scratch memory C API functions for auto-released memory on next gc.
+  Scratch memory differs from normal GCed memory as it can also be freed normally
+  for better performance.
+- Add API compatibility checking for modules. This will let native modules not load
+  when the host program is not of a compatible version or configuration.
+- Change signature of `os/execute` to be much more flexible.
+
+## 0.6.0 - 2019-05-29

+- Make `pp` configurable with dynamic binding `:pretty-format`.
+- Remove the `meta` function.
+- Add `with-dyns` for blocks with dynamic bindings assigned.

+
+## C style
+
+For changes to the VM and Core code, you will probably need to know C. Janet is programmed with
+a subset of C99 that works with Microsoft Visual C++. This means most of C99 but with the following
+omissions.
+
+* No `restrict`
+* Certain functions in the standard library are not always available
+
+In practice, this means programming for both MSVC on one hand and everything else on the other.
+The code must also build with emscripten, even if some features are not available, although
+this is not a priority.
+
+Code should compile warning free and run valgrind clean. I find that these two criteria are some
+of the easiest ways to protect against a large number of bugs in an unsafe language like C. To check for
+valgrind errors, run `make valtest` and check the output for undefined or flagged behavior.
+
+### Formatting
+
+Use [astyle](http://astyle.sourceforge.net/astyle.html) via `make format` to
+ensure a consistent code style for C.
+
+## Janet style
+
+All janet code in the project should be formatted similar to the code in core.janet.
+The auto formatting from janet.vim will work well.

+are accepted.

-Janet is a functional and imperative programming language and bytecode interpreter. It is a
-modern lisp, but lists are replaced
-by other data structures with better utility and performance (arrays, tables, structs, tuples).
-The language also bridging bridging to native code written in C, meta-programming with macros, and bytecode assembly.
+**Janet** is a programming language for system scripting, expressive automation, and
+extending programs written in C or C++ with user scripting capabilities.
 
-There is a repl for trying out the language, as well as the ability
+Janet makes a good system scripting language, or a language to embed in other programs.
+It's like Lua and GNU Guile in that regard. It has more built-in functionality and a richer core language than
+Lua, but smaller than GNU Guile or Python. However, it is much easier to embed and port than Python or Guile.

-Implemented in mostly standard C99, janet runs on Windows, Linux and macOS.
-The few features that are not standard C (dynamic library loading, compiler specific optimizations),
-are fairly straight forward. Janet can be easily ported to new platforms.

-For syntax highlighting, there is some preliminary vim syntax highlighting in [janet.vim](https://github.com/bakpakin/janet.vim).
-Generic lisp syntax highlighting should, however, provide good results.

 ## Documentation
 
-API documentation and design documents can be found in the
-[wiki](https://github.com/bakpakin/janet/wiki). There is an introduction
-section in the wiki that contains a good overview of the language.
+* For a quick tutorial, see [the introduction](https://janet-lang.org/docs/index.html) for more details.
+* For the full API for all functions in the core library, see [the core API doc](https://janet-lang.org/api/index.html).
 
-For individual bindings, use the `(doc symbol-name)` macro to get API
-documentation for the core library. For example,
+Documentation is also available locally in the REPL.
+Use the `(doc symbol-name)` macro to get API
+documentation for symbols in the core library. For example,
 ```
-(doc doc)
+(doc apply)
 ```
-Shows documentation for the doc macro.
-              
+shows documentation for the `apply` function.
+
 To get a list of all bindings in the default
-environment, use the `(all-symbols)` function.
+environment, use the `(all-bindings)` function. You
+can also use the `(doc)` macro with no arguments if you are in the REPL
+to show bound symbols.
 
-## Installation
+## Source
 
-Install a stable version of janet from the [releases page](https://github.com/bakpakin/janet/releases).
-Janet is prebuilt for a few systems, but if you want to develop janet, run janet on a non-x86 system, or
-get the latest, you must build janet from source.
+You can get the source on [GitHub](https://github.com/janet-lang/janet) or
+[SourceHut](https://git.sr.ht/~bakpakin/janet). While the GitHub repo is the official repo,
+the SourceHut mirror is actively maintained.
 
-## Usage
+## Building
 
-A repl is launched when the binary is invoked with no arguments. Pass the -h flag
-to display the usage information. Individual scripts can be run with `./janet myscript.janet`
+### macOS and Unix-like
 
-If you are looking to explore, you can print a list of all available macros, functions, and constants
-by entering the command `(all-symbols)` into the repl.

-
-## Compiling and Running
-
-Janet only uses Make and batch files to compile on Posix and windows
-respectively. To configure janet, edit the header file src/include/janet/janet.h
-before compilation.
-
-### Unix-like
-
-On most platforms, use Make to build janet.
+The Makefile is non-portable and requires GNU-flavored make.
 
 ```sh
 cd somewhere/my/projects/janet
 make
 make test
+make repl
+make install
+make install-jpm-git
 ```
 
-After building, run `make install` to install the janet binary and libs.
-Will install in `/usr/local` by default, see the Makefile to customize.
+Find out more about the available make targets by running `make help`.
 
-It's also recommended to set the `JANET_PATH` variable in your profile.
-This is where janet will look for imported libraries after the current directory.
+### Alpine Linux
+
+To build a statically-linked build of Janet, Alpine Linux + MUSL is a good combination. Janet can also
+be built inside a docker container or similar in this manner.
+
+```sh
+docker run -it --rm alpine /bin/ash
+$ apk add make gcc musl-dev git
+$ git clone https://github.com/janet-lang/janet.git
+$ cd janet
+$ make -j10
+$ make test
+$ make install
+```
+
+### 32-bit Haiku
+
+32-bit Haiku build instructions are the same as the UNIX-like build instructions,
+but you need to specify an alternative compiler, such as `gcc-x86`.
+
+```sh
+cd somewhere/my/projects/janet
+make CC=gcc-x86
+make test
+make repl
+make install
+make install-jpm-git
+```
 
 ### FreeBSD
 
-FreeBSD build instructions are the same as the unix-like build instuctions,
-but you need `gmake` and `gcc` to compile.
+FreeBSD build instructions are the same as the UNIX-like build instructions,
+but you need `gmake` to compile. Alternatively, install the package directly with `pkg install lang/janet`.
 
-```
+```sh
 cd somewhere/my/projects/janet
-gmake CC=gcc
-gmake test CC=gcc
+gmake
+gmake test
+gmake repl
+gmake install
+gmake install-jpm-git
 ```
 
+### NetBSD
+
+NetBSD build instructions are the same as the FreeBSD build instructions.
+Alternatively, install the package directly with `pkgin install janet`.
+
+### illumos
+
+Building on illumos is exactly the same as building on FreeBSD.
+
 ### Windows
 
-1. Install [Visual Studio](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=15#)
-or [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15#)
-2. Run a Visual Studio Command Prompt (cl.exe and link.exe need to be on the PATH) and cd to the directory with janet.
-3. Run `build_win` to compile janet.
+1. Install [Visual Studio](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=15#) or [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15#).
+2. Run a Visual Studio Command Prompt (`cl.exe` and `link.exe` need to be on your PATH) and `cd` to the directory with Janet.
+3. Run `build_win` to compile Janet.
 4. Run `build_win test` to make sure everything is working.
 
-### Emscripten
+To build an `.msi` installer executable, in addition to the above steps, you will have to:
 
-To build janet for the web via [Emscripten](https://kripken.github.io/emscripten-site/), make sure you
-have `emcc` installed and on your path. On a linux or macOS system, use `make janet.js` to build
-`janet.js` and `janet.wasm` - both are needed to run janet in a browser or in node.
-The JavaScript build is what runs the repl on the main website,
-but really serves mainly as a proof of concept. Janet will run much slower in a browser.
-Building with emscripten on windows is currently unsupported.
+5. Install, or otherwise add to your PATH the [WiX 3.14 Toolset](https://github.com/wixtoolset/wix3/releases).
+6. Run `build_win dist`.
 
-## Examples
+Now you should have an `.msi`. You can run `build_win install` to install the `.msi`, or execute the file itself.
 
-See the examples directory for some example janet code.
+### Meson
 
-## SQLite bindings
+Janet also has a build file for [Meson](https://mesonbuild.com/), a cross-platform build
+system. Although Meson has a Python dependency, Meson is a very complete build system that
+is maybe more convenient and flexible for integrating into existing pipelines.
+Meson also provides much better IDE integration than Make or batch files, as well as support
+for cross-compilation.
 
-There are some sqlite3 bindings in the directory natives/sqlite3. They serve mostly as a
-proof of concept external c library. To use, first compile the module with Make.
+For the impatient, building with Meson is as follows. The options provided to
+`meson setup` below emulate Janet's Makefile.
 
 ```sh
-make natives
+git clone https://github.com/janet-lang/janet.git
+cd janet
+meson setup build \
+          --buildtype release \
+          --optimization 2 \
+          --libdir /usr/local/lib \
+          -Dgit_hash=$(git log --pretty=format:'%h' -n 1)
+ninja -C build
+
+# Run the binary
+build/janet
+
+# Installation
+ninja -C build install
 ```
 
-Next, enter the repl and create a database and a table.
+## Development
+
+Janet can be hacked on with pretty much any environment you like, but for IDE
+lovers, [Gnome Builder](https://wiki.gnome.org/Apps/Builder) is probably the
+best option, as it has excellent Meson integration. It also offers code completion
+for Janet's C API right out of the box, which is very useful for exploring. VSCode, Vim,
+Emacs, and Atom each have syntax packages for the Janet language, though.
+
+## Installation
+
+If you just want to try out the language, you don't need to install anything.
+In this case you can also move the `janet` executable wherever you want on
+your system and run it.  However, for a fuller setup, please see the
+[Introduction](https://janet-lang.org/docs/index.html) for more details.
+
+## Usage
+
+A REPL is launched when the binary is invoked with no arguments. Pass the `-h` flag
+to display the usage information. Individual scripts can be run with `./janet myscript.janet`.
+
+If you are looking to explore, you can print a list of all available macros, functions, and constants
+by entering the command `(all-bindings)` into the REPL.

 ```
 
-Finally, close the database connection when done with it.
+If installed, you can also run `man janet` to get usage information.
 
+## Embedding
+
+Janet can be embedded in a host program very easily. The normal build
+will create a file `build/janet.c`, which is a single C file
+that contains all the source to Janet. This file, along with
+`src/include/janet.h` and `src/conf/janetconf.h`, can be dragged into any C
+project and compiled into it. Janet should be compiled with `-std=c99`
+on most compilers, and will need to be linked to the math library, `-lm`, and
+the dynamic linker, `-ldl`, if one wants to be able to load dynamic modules. If
+there is no need for dynamic modules, add the define
+`-DJANET_NO_DYNAMIC_MODULES` to the compiler options.
+
+See the [Embedding Section](https://janet-lang.org/capi/embedding.html) on the website for more information.
+
+## Discussion
+
+Feel free to ask questions and join the discussion on the [Janet Zulip Instance](https://janet.zulipchat.com/)
+
+## FAQ
+
+### How fast is it?
+
+It is about the same speed as most interpreted languages without a JIT compiler. Tight, critical
+loops should probably be written in C or C++ . Programs tend to be a bit faster than
+they would be in a language like Python due to the discouragement of slow Object-Oriented abstraction
+with lots of hash-table lookups, and making late-binding explicit. All values are boxed in an 8-byte
+representation by default and allocated on the heap, with the exception of numbers, nils and booleans. The
+PEG engine is a specialized interpreter that can efficiently process string and buffer data.
+
+The GC is simple and stop-the-world, but GC knobs are exposed in the core library and separate threads
+have isolated heaps and garbage collectors. Data that is shared between threads is reference counted.
+
+YMMV.
+
+### Where is (favorite feature from other language)?
+
+It may exist, it may not. If you want to propose a major language feature, go ahead and open an issue, but
+it will likely be closed as "will not implement". Often, such features make one usecase simpler at the expense
+of 5 others by making the language more complicated.
+
+### Is there a language spec?
+
+There is not currently a spec besides the documentation at <https://janet-lang.org>.
+
+### Is this Scheme/Common Lisp? Where are the cons cells?
+
+Nope. There are no cons cells here.
+
+### Is this a Clojure port?
+
+No. It's similar to Clojure superficially because I like Lisps and I like the aesthetics.
+Internally, Janet is not at all like Clojure, Scheme, or Common Lisp.
+
+### Are the immutable data structures (tuples and structs) implemented as hash tries?
+
+No. They are immutable arrays and hash tables. Don't try and use them like Clojure's vectors
+and maps, instead they work well as table keys or other identifiers.
+
+### Can I do object-oriented programming with Janet?
+
+To some extent, yes. However, it is not the recommended method of abstraction, and performance may suffer.
+That said, tables can be used to make mutable objects with inheritance and polymorphism, where object
+methods are implemented with keywords.
+
+```clj
+(def Car @{:honk (fn [self msg] (print "car " self " goes " msg)) })
+(def my-car (table/setproto @{} Car))
+(:honk my-car "Beep!")
 ```
-janet:6:> (sql/close db)
-nil
-```
+
+### Why can't we add (feature from Clojure) into the core?
+
+Usually, one of a few reasons:
+- Often, it already exists in a different form and the Clojure port would be redundant.
+- Clojure programs often generate a lot of garbage and rely on the JVM to clean it up.
+  Janet does not run on the JVM and has a more primitive garbage collector.
+- We want to keep the Janet core small. With Lisps, a feature can usually be added as a library
+  without feeling "bolted on", especially when compared to ALGOL-like languages. Adding features
+  to the core also makes it a bit more difficult to keep Janet maximally portable.
+
+### Can I bind to Rust/Zig/Go/Java/Nim/C++/D/Pascal/Fortran/Odin/Jai/(Some new "Systems" Programming Language)?
+
+Probably, if that language has a good interface with C. But the programmer may need to do
+some extra work to map Janet's internal memory model to that of the bound language. Janet
+also uses `setjmp`/`longjmp` for non-local returns internally. This
+approach is out of favor with many programmers now and doesn't always play well with other languages
+that have exceptions or stack-unwinding.
+
+### Why is my terminal spitting out junk when I run the REPL?
+
+Make sure your terminal supports ANSI escape codes. Most modern terminals will
+support these, but some older terminals, Windows consoles, or embedded terminals
+will not. If your terminal does not support ANSI escape codes, run the REPL with
+the `-n` flag, which disables color output. You can also try the `-s` flag if further issues
+ensue.
+
+## Why is it called "Janet"?
+
+Janet is named after the almost omniscient and friendly artificial being in [The Good Place](https://en.wikipedia.org/wiki/The_Good_Place).

+Janet is a functional and imperative programming language and bytecode interpreter.
+It is a Lisp-like language, but lists are replaced by other data structures
+(arrays, tables, structs, tuples). The language also features bridging
 to native code written in C, meta-programming with macros, and bytecode assembly.
 
 There is a repl for trying out the language, as well as the ability to run script files.

+The repl keybindings are loosely based on a subset of GNU readline, although
+Janet does not use GNU readline internally for the repl. It is a limited
+substitute for GNU readline, and does not handle
+utf-8 input or other mutlibyte input well.
+
+To disable the built-in repl input handling, pass the \fB\-s\fR option to Janet, and
+use a program like rlwrap with Janet to provide input.
+
+For key bindings that operate on words, a word is considered to be a sequence
+of characters that does not contain whitespace.
