 ## Installation
 
-Install a stable version of janet from the [releases page](https://github.com/janet-lang/janet/releases).
+See [the Introduction](https://janet-lang.org/introduction.html) for more details.
-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. Janet is in alpha and may change
-in backwards incompatible ways.
-
-### Windows
-
-On Windows, the easiest way to install is via the [scoop](https://scoop.sh)
-package manager. You will first need to add the janet-lang bucket, and then you can install janet
-normally.
-
-```
-scoop bucket add janet-lang https://github.com/janet-lang/scoop
-scoop install janet

-## Compiling and Running
-
-Janet only requires 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.
-
-### macos and Unix-like
-
-On most platforms, use Make to build janet. The resulting binary will be in `build/janet`.
-
-```sh
-cd somewhere/my/projects/janet
-make
-make test
-```
-
-After building, run `make install` to install the janet binary and libs.
-Will install in `/usr/local` by default, see the Makefile to customize.
-
-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.
-
-### FreeBSD
-
-FreeBSD build instructions are the same as the unix-like build instuctions,
-but you need `gmake` and `gcc` to compile.
-
-```
-cd somewhere/my/projects/janet
-gmake CC=gcc
-gmake test CC=gcc
-```
-
-### 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.
-4. Run `build_win test` to make sure everything is working.
-
-Alternatively, you can try the Meson build system setup.
-
-### Emscripten
-
-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 emscripten` 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 slower in a browser.
-Building with emscripten on windows is currently unsupported.
-
-## Meson
-
-Janet also has a build file for [Meson](https://mesonbuild.com/), a cross platform build
-system. This is not currently the main supported build system, but should work on any
-system that supports meson. Meson also provides much better IDE integration than Make or batch files.
