+Git 2.17 is available on JADE.  You do not need to load any module files to access it.
+
+Cloning/pushing to/pulling from online Git repositories
+-------------------------------------------------------
+
+JADE does not have direct Internet access so you need to tell Git to communicate with GitHub/GitLab via a proxy.
+
+You can configure proxy connections per-repository with:
+
+.. code-block:: sh
+
+   git config http.proxy $http_proxy
+   git config https.proxy $https_proxy
+
+Or globally configure the use of a particular proxy with:
+
+.. code-block:: sh
+
+   git config --global http.proxy $http_proxy
+   git config --global https.proxy $https_proxy
+
+Then ensure you use ``https://`` rather than ``git://`` when cloning repositories on Jade.
