For developers

You should be a user before becoming a developer, please read the part for users above.

There are 3 kinds: core core development, module development, and theme development. Only *nix environment is supported for development.

After installing, you can start creating modules, themes, or modifying the core.


After checking out the latest source code using Git (you should be familiar with Git):

  • Rails and many plugins are installed as git submodules (OpenKH always tries to use latest technologies): git submodule init && git submodule update
  • To download additional things and create additional directories (these have been prepared in the ZIP file for users): rake developer:prepare
  • Perform installation as instructed in the part for users above
