 5. Commit
- 
-  First, ensure that if you have several commits, they are **squashed into a single commit**:
 
-  ```
-  git remote add upstream https://github.com/discourse/discourse.git
-  git fetch upstream
-  git checkout new_discourse_branch
-  git rebase upstream/master
-  git rebase -i
-
-  < Choose 'squash' for all of your commits except the first one. >
-  < Edit the commit message to make sense, and describe all your changes. >
-
-  git push origin new_discourse_branch -f
-  ```
-
-  Now you're ready to commit:
-
-  ```
-  git commit -a
-  ```
+  For every commit please write a short (max 72 characters) summary in the first line followed with a blank line and then more detailed descriptions of the change. Use markdown syntax for simple styling.
 
   **NEVER leave the commit message blank!** Provide a detailed, clear, and complete description of your commit!

 10. Responding to Feedback
 
   The Discourse team may recommend adjustments to your code. Part of interacting with a healthy open-source community requires you to be open to learning new techniques and strategies; *don't get discouraged!* Remember: if the Discourse team suggest changes to your code, **they care enough about your work that they want to include it**, and hope that you can assist by implementing those revisions on your own.
