+          Enable Git daemon, which allows public hosting  of git repositories
+          without any access controls. This is mostly intended for read-only access.
+
+          You can allow write access by setting daemon.receivepack configuration
+          item of the repository to true. This is solely meant for a closed LAN setting
+          where everybody is friendly.
+
+          If you need any access controls, use something else.

+          if you set base-path to /srv/git, then if you later try to pull
+          git://example.com/hello.git, Git daemon will interpret the path as /srv/git/hello.git.
