+# GitLab Flow
+
+- A simplified branching strategy
+- All features and fixes first go to master
+- Allows for 'production' or 'stable' branches
+- Bug fixes/hot fix patches are cherry-picked from master
+
+---
+
+# Feature branches
+
+- Create a feature/bugfix branch to do all work
+- Use merge requests to merge to master

+
+# Production branch
+
+- One, long-running production release branch
+  as opposed to individual stable branches
+- Consider creating a tag for each version that gets deployed
+

+
+# Production branch

+
+# Release branch
+
+- Useful if you release software to customers
+- When preparing a new release, create stable branch
+  from master
+- Consider creating a tag for each version
+- Cherry-pick critical bug fixes to stable branch for patch release
+- Never commit bug fixes directly to stable branch
