 Every script can be invoked as a git subcommand such as `git dirs`. Every script
 should respond to the `-h` flag with its expected parameters and options.
 
-# Scripts
+## Scripts
 
-## `git-close-current-branch`
+### `git-close-current-branch`
 
 Closes the current branch if it's been merged into the mainline. Intended usage
 is after a pull request for the current branch has been merged into mainline and
 the remote branch deleted. See `git close-current-branch -h` for details.
 
-## `git-close-merged`
+### `git-close-merged`
 
 Closes all local branches that have been merged into HEAD (or a specified
 branch). This command is upstream-aware, and can be instructed to close remote
 branches as well. See `git close-merged -h` for details.
 
-## `git-dirs`
+### `git-dirs`
 
 Prints a list of the most recently checked-out branches. See `git dirs -h` for
 details.
 
-## `git-find-merge`
+### `git-find-merge`
 
 Finds the oldest merge in the first-parent history of a given branch that a
 given commit is reachable from. This can be said to be the merge that introduced
 a commit into a given branch. See `git find-merge -h` for details.
 
-## `git-find-tree`
+### `git-find-tree`
 
 Finds the full path to a given filename path in a given tree-ish. This may
 optionally produce output that refers to the file's blob, for use with other git
 commands. See `git find-tree -h` for details.
 
-## `git-fugitive`
+### `git-fugitive`
 
 Displays a given revision or file in [vim-fugitive][]. See `git fugitive -h`
 for details.

 details.
