Quick start: ============ Assume you already have a github account. Lets your account name is "username". First you need to fork 2 repos: - ChibiOS-gitmain - ChibiOS-contrib Make local clone of your fork git clone git@github.com:username/ChibiOS-gitmain.git Make local branch for your feature ``` cd ChibiOS-gitmain git branch feature git checkout feature ``` There is no code from ChibiOS-contrib in your repo. We have to connect ChibiOS-contrib as a git submodule git submodule add git@github.com:username/ChibiOS-Contrib.git community Make branch again, but now in freshly connected submodule cd community git branch feature git checkout feature Hack, hack, hack... Commit our changes and push to server. Note: you have to do this for both repositories. First ChibiOS-Contrib cd community git add . git commit -m "Feature implemented" git push origin feature:feature Now for parent repo cd .. git add . git commit -m "Feature implemented" git push origin feature:feature Now all your changes published on github. Just use web interface to send pull 2 requests: for ChibiOS-contrib and for ChibiOS-gitmain.
