+
+[^1]:
+    You can use any standardized Git server. Depending on the server used,
+    licenses for the Git server may be required.
+
+[^2]:
+    You need a valid TeamForCapella license and TeamForCapella server installed
+    and integrated in the Collaboration Manager.
+
+[^3]:
+    For the basic workflow, a simple Git knowledge that includes commit, pull
+    and push is sufficient. However, it is necessary to have at least one Git
+    expert in the project to deal with potential merge conflicts and unexpected
+    situations.
+
+[^4]:
+    To review changes, the Eclipse EMF diff/merge tool can be used. However, in
+    practice this proves to be too time-consuming, as many changes become
+    confusing very quickly.
