+NAME
+----
+git-maintenance - Run tasks to optimize Git repository data
+
+
+SYNOPSIS
+--------
+[verse]
+'git maintenance' run [<options>]
+
+
+DESCRIPTION
+-----------
+Run tasks to optimize Git repository data, speeding up other Git commands
+and reducing storage requirements for the repository.
+
+Git commands that add repository data, such as `git add` or `git fetch`,
+are optimized for a responsive user experience. These commands do not take
+time to optimize the Git data, since such optimizations scale with the full
+size of the repository while these user commands each perform a relatively
+small action.
+
+The `git maintenance` command provides flexibility for how to optimize the
+Git repository.
+
+SUBCOMMANDS
+-----------
+
+run::
+ Run one or more maintenance tasks.
+
+TASKS
+-----
+
+gc::
+ Clean up unnecessary files and optimize the local repository. "GC"
+ stands for "garbage collection," but this task performs many
+ smaller tasks. This task can be expensive for large repositories,
+ as it repacks all Git objects into a single pack-file. It can also
+ be disruptive in some situations, as it deletes stale data. See
+ linkgit:git-gc[1] for more details on garbage collection in Git.
+
+OPTIONS
+-------
+--auto::
+ When combined with the `run` subcommand, run maintenance tasks
+ only if certain thresholds are met. For example, the `gc` task
+ runs when the number of loose objects exceeds the number stored
+ in the `gc.auto` config setting, or when the number of pack-files
+ exceeds the `gc.autoPackLimit` config setting.
