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.

Remap all the path requests as relative to the given path. For example,
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.

Publish all directories that look like Git repositories (have the objects
and refs subdirectories), even if they do not have the git-daemon-export-ok file.
If disabled, you need to touch .git/git-daemon-export-ok in each repository
you want the daemon to publish.
Warning: enabling this without a repository whitelist or basePath
publishes every git repository you have.

Warning: leaving this empty and enabling exportAll publishes all
repositories in your filesystem or basePath if specified.
