+2. Create a new branch from master
+
+    ```
+    git checkout master
+    git pull origin master
+    git checkout -b your-branch
+    ```
+
+3. Make your documentation updates by editing the source files in 
+`docs-source/content`.
+
+4. If you wish to view your changes you can run the site locally using 
+these commands; the site will be available on the URL shown here:
+
+    ```
+    cd docs-source
+    hugo server -b http://localhost:1313/weblogic-kubernetes-operator
+    ```
+
+5. When you are ready to submit your changes, push your branch to `origin`
