 As noted earlier, `vcsh` will set <$GIT_DIR> and <$GIT_WORK_TREE> to the
 appropriate values for fake bare git repositories.
 
+## CONFIG
+
+There are several ways to turn the various knobs on `vcsh`. In order of
+ascending precedence, they are:
+
+* `VARIABLE=foo vcsh`
+* </etc/vcsh/config>
+* <$XDG_CONFIG_HOME/vcsh/config>
+* `vcsh -c <file>`
+
+Please note that those files are sourced. Any and all commands will be
+executed in the context of your shell.
+
+Interesting knobs you can turn:
+
+* <$VCSH_GITIGNORE>:
+  Can be either <exact> or <recursive>.
+
+  <exact> will seed the repo-specific <.gitignore> with all file and directory
+  names which `git ls-files` returns.
+
+  <recursive> will descend through all directories recursively additionally to
+  the above.
+
+  Defaults to <exact>.
+
+Less interesting knobs you could turn:
+
+* <$VCSH_DEBUG>:
+  Enter debug mode.
+
+* <$XDG_CONFIG_HOME>:
+  As specified in the 'XDG Base Directory Specification', see
+  <http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>
+
+  Defaults to <$HOME/.config>.
+
+* <$VCSH_REPO_D>:
+  The directory where repositories are read from and stored.
+
+  Defaults to <$XDG_CONFIG_HOME/vcsh/repo.d>.
+
+* <$VCSH_HOOK_D>:
+  The directory where hooks are read from.
+
+  Defaults to <$XDG_CONFIG_HOME/vcsh/hooks-enabled>.
+
+* <$VCSH_BASE>:
+  The directory where repositories are checked out to.
+
+  Defaults to <$HOME>.

+## INTEROPERABILITY
 
-As of this writing (June 2012), `vcsh` does not work with `git submodule` due

+If you rely on `git submodule`, use `git` 1.7.12 or later. Earlier versions
