+The source code resides in `src/main` (gradle project determined by `versions/mainVersion` e.g. with `11404` it'll be `:1.14.4`) and is automatically passed through the

 Do **NOT** edit any of the code in `versions/$MCVERSION/build/` as it is automatically generated and will be overwritten without warning.
 
 You can pass the original source code through the preprocessor if you wish to develop/debug with another version of Minecraft:
