+The following workflow works fine for most developers:
+
+--------------------------------------------------------------------------------
+# get latest upstream master branch
+git clone https://github.com/telmich/cdist.git
+
+# update if already existing
+cd cdist; git fetch -v; git merge origin/master

+# create a new branch for your feature/bugfix
+cd cdist # if you haven't done before
+git checkout -b documentation_cleanup

+# clone the cdist repository on github if you haven't done so

+# configure your repo to know about your clone (only once)
+git remote add github git@github.com:YOURUSERNAME/cdist.git
+
+# push the new branch to github 
+git push github documentation_cleanup

+# (or everything)
+git push --mirror github
+
+# create a pull request at github (use a browser)
+# *fixthingsbecausequalityassurancefoundissuesinourpatch*
+*hack*
+
+# push code to github again
+git push ... # like above
+
+# add comment that everything should be green now (use a browser)

+If at any point you want to go back to the original master branch, you can
+use **git stash** to stash your changes away:

+# assume you are on documentation_cleanup
+git stash
+
+# change to master and update to most recent upstream version
+git checkout master
+git fetch -v origin
