+# Workflow - Request New Sources / Change Sources
+This is the workflow 
+
+1. Create a forked repository of the current databuffer configuration repository and clone it to your home folder:
+
+```bash
+ssh sf-lc7.psi.ch
+cd ~
+gitutils fork -c archiver_config/sf_databuffer
+```
+
+2. Go to the cloned repository and add/edit the files needed
+```bash
+cd ~/sf_databuffer
+...
+```
+
+3. Commit your changes in the cloned local copy and push the changes to the server.
+```bash
+git commit -a -m "my commit message"
+git push
+```
+
+4. Use `gitutils` to create automatically a merge request to the main repository on the git server.
+
+```bash
+gitutils merge -t "My Changes" -d "my merge request message"
+```
+
+Be aware: The best is to wait until a merge request was approved/closed before you create/open a new one!
+
+More details on the gitutils command can be found at: https://gitutils.readthedocs.io/en/latest/
