+# Contributing guidelines for the project
+
+## Setting up a Workspace
+ViaFabricPlus uses Gradle, to make sure that it is installed properly you can check [Gradle's website](https://gradle.org/install/).
+1. Clone the repository using `git clone https://github.com/ViaVersion/ViaForge`.
+2. CD into the local repository.
+3. Run `./gradlew build`.
+4. Open the folder as a Gradle project in your preferred IDE.
+5. Run the mod.
+
+## Add a new feature or fix a bug
+1. Create a new branch for your feature/bugfix (e.g. `feature/fix-xyz` or `fix/fix-xyz`)
+2. Implement your feature/bugfix and make sure it works correctly
+3. Clean your code and make sure it is readable and understandable (e.g. use proper variable names)
+4. Use the Google java code style (https://google.github.io/styleguide/javaguide.html) and format your code accordingly
+5. Create a pull request and wait for it to be reviewed and merged.
+6. You're done, congrats!
+
+## Add support for a new Minecraft version
+1. Create a new branch for the new version (e.g. `update/1.20.6`)
+2. Create a new `viaforge-mc<version>` folder in the root directory of the project
+3. Add a `gradle.properties` file with the `forge_version` set (Available at https://files.minecraftforge.net/)
+4. Register it inside the `settings.gradle` file
+5. Copy the code from the previous version and update it accordingly
+
+### Build logic
+The `build.gradle` file contains the shared build code for all submodules. Build code for only specific versions
+of the game can be wrapped with checks using the `versionId` integer which will be parsed from the `forge_version`.
+
+An example would be:
+````groovy
+if (versionId >= 1_13_2) {
+    // We don't need to package mixins into Forge 1.13+ jars, since Forge already has it
+    exclude("org/spongepowered/**")
+}
+````
+
+### Notes
+Shared source code is inside the ``src/main/java`` root folder, while version-specific code is inside the ``/viaforge-mc<version>`` folders.

+- April Fools (3D Shareware, 20w14infinite)
+- Combat Snapshots (Combat Test 8c)
 
-### Can you add new textures and blocks from higher versions?
+## How to (Users)
-No, because it is too time-consuming
 
-### ViaVersion throws an error, or I can't access a server, what should I do?
+ViaForge can be installed on 1.12.2, 1.16.5, 1.17.1, 1.18.2, 1.19.2, 1.19.4, 1.20.4 and 1.20.6 Forge client versions. <br>
-First of all see if it's because of an installed mod, otherwise come to the support Discord and tell me logs, mc version etc.
 
-### Certain collisions or other items bug, can you fix it?
+The ``legacy-1.8`` also supports Minecraft 1.8.9.
-No
 
-## For developers
+Dev builds: https://ci.viaversion.com/view/Platforms/job/ViaForge/
-### How does it work?
-![](images/via-expl.png)
 
-### Project Structure
+If you encounter any issues, please report them on either:
-All ViaForge versions from Minecraft version 1.12 onwards are on the `master` branch. <br>
+- [the issue tracker](https://github.com/ViaVersion/ViaForge/issues)
-The names of the submodules indicate the version, they are always given in the format `mc-<version name without .>`. <br>
+- [the ViaVersion Discord](https://discord.gg/viaversion)
-`Minecraft 1.12.2` - `mc1122`
 
-### ViaForge for Minecraft 1.8
+## How to (Developers)
-Since ForgeGradle for Minecraft 1.8 is too old, it has its own branch called `legacy-1.8`
 
-### I want ViaForge in my own utility mod
+See [this project](https://github.com/ViaVersionMCP/ViaMCP) for a copy-paste solution to include ViaForge into your MCP based project.
-Just take a look at my other Project called `ViaMCP`: https://github.com/FlorianMichael/ViaMCP
 
-## Other Via related Projects
+### How to build
