+This package provides a central git qube, named sys-git.
+By default the qube has no netvm, but you can set one if you wish.
+
+Some configuration is needed.
+
+# Setting up a new repository
+
+## sys-git
+In sys-git, repositories are stored bare under /home/user/repos
+First, prepare a repository:
+```
+mkdir repos/X
+cd repos/X
+git init --bare
+```
+
+## prepare client
+Then prepare a qube by running:
+`qubesctl --skip0-dom0 --targets=QUBE state.apply git.install_client`
+
+## Work in the client
+You can then use that repository as usual.
+To push to sys-git you must first-  
+`git push --set-upstream sg master`
+
+After making more commits,
+`git push `
+
+# Working with an existing repository
+
+## prepare client, if necessary
+Prepare a qube by running:
+`qubesctl --skip0-dom0 --targets=QUBE state.apply git.install_client`
+
+## Clone the repository in the client
+Configure git, as necessary.  
+Open a terminal in the qube:
+```
+mkdir X
+cd X
+git init
+add-remote sg
+git pull sg master
+```
