Guide for Contributors (Forks and Pull Requests)

• first you fork the openroberta-lab repository on github: open the repository page and in the top-right corner of the page, click Fork. You get a fork on github with URL https://github.com/<username>/openroberta-lab.git
• clone this repository to get a local copy of it. You should work on a feature branch (e.g. feature/myAdditions) derived from develop:

git clone https://github.com/<username>/openroberta-lab.git
cd openroberta-lab
git checkout develop
git checkout -b feature/myAdditions

• add the upstream repository to your local clone, because you want to synchronize on that repository and submit a pull request against it

git remote add upstream https://github.com/OpenRoberta/openroberta-lab

• now you can make changes in your feature branch, commit them and push them to your personal repository on github. Please write (more) tests and execute them often. Please use the formatter we supply in the Resources folder. This makes collaboration easy. Follow software engineering rules like KISS (keep it simple and stupid), DRY (don't repeat yourself), use meaningful names, ... ... .
• from time to time you should integrate changes from upstream into your feature branch. This is called rebasing. Sometimes you have to resolve conflicts, sometimes you are lucky and a fast-forward takes place (there is a special page explaining rebasing). After a rebase, if you push to your personal repository on github, you have to force the push:

git checkout feature/myAdditions
git fetch --all
git rebase upstream/develop
git push --force

• after you have finished your work, you can create pull request to ask for integration of your work into the upstream repository. You must rebase immediately before you do that! On the github web page of your personal repository click the Pull request button on the upper left side, select the right branches and follow the instructions.
• if you continue to work and update your your personal repository on github by pushing local changes, this will update pending pull requests.
