Download fabric for minecraft 1.16/1.17. Download the latest version of BleachHack for your Minecraft version from the releases section.
On Windows: Type %appdata% into the Windows search bar; open the folder that comes up and then open '.minecraft'.
On Mac: Click on the desktop, press Command+Shift+G, type ~/Library and press enter; then open 'Application Support' and finally '.minecraft'.
On Linux: in a terminal window, type 'xdg-open ~/.minecraft'... or if you like working at the commandline, 'cd ~/.minecraft'.
Then inside that folder, you should see a folder named 'mods'. (If you don't see one, make sure you've installed Fabric already and started Minecraft again once). That's where you'll put any mods you want to install.
Download the project. Start A Command Prompt/Terminal in the BleachHack-Fabric-(Version) folder. Generate the needed files for your preferred IDE.
Eclipse
On Windows:
gradlew genSources eclipse
On Linux:
chmod +x ./gradlew
./gradlew genSources eclipse
Start a new workspace in eclipse. Click File > Import... > Gradle > Gradle Project. Select the BleachHack-Fabric-(Version) folder.
Other IDE's
Use this link for more information. It should be pretty similar to the eclipse setup.
Here are some nice to have mods that are compatible with BleachHack, none of these require Fabric API.

If you are distributing a custom version of BleachHack or a mod with ported features of BleachHack, you are required to disclose the source code, state changes, use a compatible license, and follow the licence terms.
