+## 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_GITATTRIBUTES>:
+  Can be <none>, or any other value.
+
+  <none> will not maintain Git attributes in a special location.
+
+  If set to any other value, repo-specific gitattributes files will be maintained.
+
+  Defaults to <none>.
+
+* <$VCSH_GITIGNORE>:
+  Can be <exact>, <none>, or <recursive>.
+
+  <exact> will seed the repo-specific ignore file with all file and directory
+  names which `git ls-files` returns.
+
+  <none> will not write any ignore file.
+
+  <recursive> will descend through all directories recursively additionally to
+  the above.
+
+  Defaults to <exact>.
+
+* <$VCSH_VCSH_WORKTREE>:
+  Can be <absolute>, or <relative>.
+
+  <absolute> will set an absolute path; defaulting to <$HOME>.
+
+  <relative> will set a path relative to <$GIT_DIR>.
+
+  Defaults to <absolute>.
+
+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>.

+## OVERLAY SYSTEM
+
+`vcsh` also provides an overlay system. Similar to hooks, the recommended
+locations are <$XDG_CONFIG_HOME/vcsh/overlays-available> and
+<$XDG_CONFIG_HOME/vcsh/overlays-enabled>.
+
+Overlays follow the same rules as hooks and you are free to overwrite any
+and all functions. Same as hooks, you can use global or repository-specific
+overlays by using either <$VCSH_OVERLAY_D/$VCSH_COMMAND> or
+<$VCSH_OVERLAY_D/$VCSH_REPO_NAME.$VCSH_COMMAND>.
+
+Please note that nothing stops you from, e.g. overwriting `status()` in
+<$VCSH_OVERLAY_D/commit>. As the overlays will be sourced and you are
+replacing arbitrary functions, any and all features may stop working, or you
+may even lose data.
+
+You have been warned.
