+# Gitflow
+
+> Describes JIRA-based gitflow
+
+1. Create a JIRA ticket before you start working.
+
+2. One ticket should preferably be a single commit.
+
+3. Keep the commit graph as simple as possible.
+
+4. Don't change the revision history of branches you share with each other.
+
+5. Make sure to get reviews from reviewers.
+6. merge your own pull requests.
