# Contributing If you want to contribute to `bld` or customize it, all you have to do is clone the GitHub repository and update the [RIFE2/core](https://github.com/rife2/rife2-core) submodule: ```console git clone git@github.com:rife2/bld.git cd bld git submodule init git submodule update ``` Then use `bld` to build itself: ```console ./bld compile ``` The project has an IntelliJ IDEA project structure. You can just open it after all the dependencies were downloaded and peruse the code.
