+.SH DESCRIPTION
+.PP
+Git is a distributed version control system.
+This means that each repository contains a full copy of the history.
+This history is then synced between computers as needed.
+
+.PP
+These programs provide tools to manage and interoperate with
+repositories hosted in git.
+
+.SH CONCEPTS
+
+Git stores snapshots of the working directory.
+Files can either be in a tracked or untracked state.
+Each commit takes the current version of all tracked files and
+adds them to a new commit.
+
+This history is stored in the
+.I .git
+directory.
+This suite of
+.I git
+tools provides a file interface to the
+.I .git
+directory mounted on
+.I /mnt/git.
+Modifications to the repository are done directly to the
+.I .git
+directory, and are reflected in the file system interface.
+This allows for easy scripting, without excessive complexity
+in the file API.
+
+.SH COMMANDS
+
+.PP
+.B Git/init
+is used to create a new git repository, with no code or commits.
+The repository is created in the current directory by default.
+Passing a directory name will cause the repository to be created
+there instead.
+Passing the
+.B -b
+option will cause the repository to be initialized as a bare repository.
+Passing the
+.B -u
+.I upstream
+option will cause the upstream to be configured to
+.I upstream.
+
+.PP
+.B Git/clone
+will take an existing repository, served over either the
+.I git://
+or
+.I ssh://
+protocols.
+The first argument is the repository to clone.
+The second argument, optionally, specifies the location to clone into.
+If not specified, the repository will be cloned into the last path component
+of the clone source, with the
+.I .git
+stripped off if present.
+
+.PP
+.B Git/push
+is used to push the current changes to a remote repository.
+When no arguments are provided, the remote repository is taken from
+the origin configured in
+.I .git/config,
+and only the changes on the current branch are pushed.
+When passed the
+.I -a
+option, all branches are pushed.
+When passed the
+.I -u upstream
+option, the changed are pushed to
+.I upstream
+instead of the configured origin.
+When given the
+.I -r
+option, the branch is deleted from origin, instead of updated.
+
+.PP
+.B Git/revert
+restores the named files from HEAD. When passed the -c flag, restores files from
+the named commit.
+
+.PP
+.B Git/pull
+behaves in a similar manner to git/push, however it gets changes from
+the upstream repository.
+After fetching, it checks out the changes into the working directory.
+When passed the
+.I -f
+option, the update of the working copy is suppressed.
+When passed the
+.I -u upstream
+option, the changes are pulled from
+.I upstream
+instead of the configured origin.
+
+.PP
+.B Git/serve
+serves repositories using the
+.I git://
+protocol over stdin.
+By default, it serves them read-only.
