-## What?
-ComputerCraft has always held a fond place in my heart: it's the mod which really got me into Minecraft, and it's the
-mod which has kept me playing it for many years. However, development of the original mod has slowed, as the original
-developers have had less time to work on the mod, and moved onto other projects and commitments.
+# What is CC: Restitched?
+This is a fabric port of [SquidDev-CC/CC-Tweaked](https://github.com/SquidDev-CC/CC-Tweaked). The work is a continuation of [Zundrel/cc-tweaked-fabric](https://github.com/Zundrel/cc-tweaked-fabric).
 
-CC: Tweaked (or CC:T for short) is an attempt to continue ComputerCraft's legacy. It's not intended to be a competitor
-to CC, nor do I want to take it in a vastly different direction to the original mod. Instead, CC:T focuses on making the
-ComputerCraft experience as _solid_ as possible, ironing out any wrinkles that may have developed over time.
+## CC: Restitched vs. CC: Tweaked
+CC: R tries to maintain parity with CC: T, but may be behind or divergent in some areas. If you notice a disparity please open an issue. CC: R major and minor version numbers indicate parity with the major features of that version of CC: T. Patch version numbers will not align.
 
-## Features
-CC: Tweaked contains all the features of the latest version of ComputerCraft, as well as numerous fixes, performance
-improvements and several nifty additions. I'd recommend checking out [the releases page](https://github.com/SquidDev-CC/CC-Tweaked/releases)
-to see the full set of changes, but here's a couple of the more interesting additions:
+## Resource Packs
+This mod includes textures by [Jummit](https://github.com/Jummit) that are more in line with the style of Mojang's new texture-artist, Jappa. If you prefer the original textures, enable the "Classic" resource pack.
 
- - Improvements to the `http` library, including websockets, support for other HTTP methods (`PUT`, `DELETE`, etc...)
-   and configurable limits on HTTP usage.
- - Full-block wired modems, allowing one to wrap non-solid peripherals (such as turtles, or chests if Plethora is
-   installed).
- - Pocket computers can be held like maps, allowing you to view the screen without entering a GUI.
- - Printed pages and books can be placed in item frames and held like maps.
- - Several profiling and administration tools for server owners, via the `/computercraft` command. This allows operators
-   to track which computers are hogging resources, turn on and shutdown multiple computers at once and interact with
-   computers remotely.
- - Closer emulation of standard Lua, adding the `debug` and `io` libraries. This also enables seeking within binary
-   files, meaning you don't need to read large files into memory.
- - Allow running multiple computers on multiple threads, reducing latency on worlds with many computers.
-
-## Relation to CCTweaks?
-This mod has nothing to do with CCTweaks, though there is no denying the name is a throwback to it. That being said,
-several features have been included, such as full block modems, the Cobalt runtime and map-like rendering for pocket
-computers.
+<img src="https://raw.githubusercontent.com/3prm3/cc-pack/main/pack.png" alt="CC: Restitched" width="16"  height="16"/> We also have a second resourcepack made by [3prm3](https://github.com/3prm3), it features a complete overhaul and can be enabled by enabling the `overhaul` resource pack, go check out his resource pack over [here](https://github.com/3prm3/cc-pack/)!
 
 ## Contributing
-Any contribution is welcome, be that using the mod, reporting bugs or contributing code. In order to start helping
-develop CC:T, you'll need to follow these steps:
+Any contribution is welcome, be that using the mod, reporting bugs or contributing code. In order to start helping develop CC: R there are a few rules;
+1) Make sure your code follows the checkstyle rules. You can test this by running `./gradle build` or `./gradle check`.
+2)  Do not alter the lua code unless those changes are taken directly from CC: Tweaked. If you wish to contribute changes to the in game rom please contribute upstream at [CC-Tweaked](https://github.com/SquidDev-CC/CC-Tweaked).
 
- - **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
- - **Setup Forge:** `./gradlew setupDecompWorkspace`
- - **Test your changes:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).

-If you need help getting started with CC: Tweaked, want to show off your latest project, or just want to chat about
-ComputerCraft we have a [forum](https://forums.computercraft.cc/) and [Discord guild](https://discord.gg/H2UyJXe)!
-There's also a fairly populated, albeit quiet [IRC channel](http://webchat.esper.net/?channels=#computercraft), if
-that's more your cup of tea.
+If you need help getting started with CC: Restitched, want to show off your latest project, or just want to chat about ComputerCraft, here is the [Forum](https://forums.computercraft.cc/) and the [Discord](https://discord.gg/H2UyJXe).
 
-I'd generally recommend you don't contact me directly (email, DM, etc...) unless absolutely necessary (i.e. in order to
-report exploits). You'll get a far quicker response if you ask the whole community!
-
-## Using
-If you want to depend on CC: Tweaked, we have a maven repo. However, you should be wary that some functionality is only
-exposed by CC:T's API and not vanilla ComputerCraft. If you wish to support all variations of ComputerCraft, I recommend
-using [cc.crzd.me's maven](https://cc.crzd.me/maven/) instead.
-
-```groovy
-dependencies {
-  maven { url 'https://squiddev.cc/maven/' }
-}
-
-dependencies {
-  implementation "org.squiddev:cc-tweaked-${mc_version}:${cct_version}"
-}
-```
-
-You should also be careful to only use classes within the `dan200.computercraft.api` package. Non-API classes are
-subject to change at any point. If you depend on functionality outside the API, file an issue, and we can look into
-exposing more features.
+## Perpheral mods
+Unfortunately, CC: Restitched does not have as many peripherals mods available as CC: Tweaked. If you're an interested mod developer, please check out our `api` package. If you've already made a mod with CC: R peripheral support OR if you're a player who found a mod with ComputerCraft integration, please open an [issue here](https://github.com/cc-tweaked/cc-restitched/issues/new?assignees=&labels=peripheralShoutout&template=peripheral_shoutout.md) to let us know and we'll add it to the list!

+# ![CC: Tweaked](logo.png)
+CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles and more to the game. A fork of the
+much-beloved [ComputerCraft], it continues its legacy with better performance, stability, and a wealth of new features.
+
+CC: Tweaked can be installed from [CurseForge] or [Modrinth]. It requires the [Minecraft Forge][forge] mod loader, but
+[versions are available for Fabric][ccrestitched].
+
+## Features
+Controlled using the [Lua programming language][lua], CC: Tweaked's computers provides all the tools you need to start
+writing code and automating your Minecraft world.
+
+![A ComputerCraft terminal open and ready to be programmed.](images/basic-terminal.png){.big-image}
+
+While computers are incredibly powerful, they're rather limited by their inability to move about. *Turtles* are the
+solution here. They can move about the world, placing and breaking blocks, swinging a sword to protect you from zombies,
+or whatever else you program them to!
+
+![A turtle tunneling in Minecraft.](images/turtle.png){.big-image}
+
+Not all problems can be solved with a pickaxe though, and so CC: Tweaked also provides a bunch of additional peripherals
+for your computers. You can play a tune with speakers, display text or images on a monitor, connect all your
+computers together with modems, and much more.
+
+Computers can now also interact with inventories such as chests, allowing you to build complex inventory and item
+management systems.
+
+![A chest's contents being read by a computer and displayed on a monitor.](images/peripherals.png){.big-image}
+
+## Getting Started
+While ComputerCraft is lovely for both experienced programmers and for people who have never coded before, it can be a
+little daunting getting started. Thankfully, there's several fantastic tutorials out there:
+
+ - [Direwolf20's ComputerCraft tutorials](https://www.youtube.com/watch?v=wrUHUhfCY5A "ComputerCraft Tutorial Episode 1 - HELP! and Hello World")
+ - [Sethbling's ComputerCraft series](https://www.youtube.com/watch?v=DSsx4VSe-Uk "Programming Tutorial with Minecraft Turtles -- Ep. 1: Intro to Turtles and If-Then-Else_End")
+ - [Lyqyd's Computer Basics 1](http://www.computercraft.info/forums2/index.php?/topic/15033-computer-basics-i/ "Computer Basics I")
+
+Once you're a little more familiar with the mod, the sidebar and links below provide more detailed documentation on the
+various APIs and peripherals provided by the mod.
+
+If you get stuck, do pop in to the [Minecraft Computer Mod Discord guild][discord] or ComputerCraft's
+[IRC channel][irc].

+```
+8b4a01df27ff7f6fa9ffd9c2188c6e3166edd515

+HTTP rules now allow filtering by port
+
+The HTTP filtering system becomes even more complex! Though in this
+case, it's pretty minimal, and definitely worth doing.
+
+For instance, the following rule will allow connecting to localhost on
+port :8080.
+
+    [[http.rules]]
+    host = "127.0.0.1"
+    port = 8080

+Minecraft propagates "strong" redstone signals (such as those directly
+from comparators or repeaters) through solid blocks. This includes
+computers, which is a little annoying as it means one cannot feed

+```
+f6160bdc57b3d9850607c2c7c2ce9734b4963478
+Fix players not getting advancements when they own turtles
+
+When we construct a new ServerPlayerEntity (and thus TurtlePlayer), we
+get the current (global) advancement state and call .setPlayer() on it.
+
+As grantCriterion blocks FakePlayers from getting advancements, this
+means a player will no longer receive any advancements, as the "wrong"
+player object is being consulted.
+
+As a temporary work around, we attempt to restore the previous player to
+the advancement store. I'll try to upstream something into Forge to
+resolve this properly.
