+# Workflow
+
+This is a git-specific workflow that helps you contribute flawlessly you JuPedSim.
+
+- Clone the project (for the first time)
+
+```python
+    git clone https://cst.version.fz-juelich.de/jupedsim/jpscore.git
+```
+
+- Change to the developement branch and create a branch with your feature.
+
+```python
+    git checkout developement 
+    git checkout -b feature_name
+```
+
+- Write code and Commit changes
+
+```python
+    git commit -m "Describe here your changes"
+```
+
+- Push your branch to GitLab. But before doing so, [test](pushing) your code.
+
+```python
+    git push origin feature_name
+```
+    
+- Create a merge request
+
+    a *Master* will review your code & merge it to the developement branch (maybe).

+## Tips Working with Git
+1. Pull frequently.
+2. Commit often, but don’t push every commit.
+3. Create one commit per unit of work. Break your changes down into multiple commits, e.g. "fix bug", "add documentation", etc.
+4. Push when changes are tested.
