 ## Get involved
 
+To get started, you'll need to fork or branch, and we'll merge based on PR's.
+
+If you are a contributor to the project, simply clone:
+
+```
+git clone git@github.com:Firstyear/kanidm.git
+```
+
+If you are forking, then Fork in github and clone with:
+
+```
+git clone https://github.com/Firstyear/kanidm.git
+cd kanidm
+git remote add myfork git@github.com:<YOUR USERNAME>/kanidm.git
+```
+
+Select and issue (and always feel free to reach out to us for advice!), and create a branch to
+start working:
+
+```
+git branch <feature-branch-name>
+git checkout <feature-branche-name>
+```
+
+When you are ready for review (even if the feature isn't complete and you just want some advice)
+
+```
+git commit -m 'Commit message' change_file.rs ...
+git push <myfork/origin> <feature-branch-name>
+```
+
+If you get advice or make changes, just keep commiting to the branch, and pushing to your branch.
+When we are happy with the code, we'll merge in github, meaning you can now cleanup your branch.
+
+```
+git checkout master
+git pull
+git branch -D <feature-branch-name>
+```
+
+Rebasing:
+
+If you are asked to rebase your change, follow these steps:
+
+```
+git checkout master
+git pull
+git checkout <feature-branche-name>
+git rebase master
+```
+
+Then be sure to fix any merge issues or other comments as they arise. If you have issues, you can
+always stop and reset with:
+
+```
+git rebase --abort
+```
+
