+# Branch plugin
+
+This plugin displays the current Git or Mercurial branch, fast. If in a Mercurial repository,
+also display the current bookmark, if present.
+
+To use it, add `branch` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... branch)
+```
+
+## Speed test
+
+- `hg branch`:
+
+  ```console
+  $ time hg branch
+  0.11s user 0.14s system 70% cpu 0.355 total
+  ```
+
+- branch plugin:
+
+  ```console
+  $ time zsh /tmp/branch_prompt_info_test.zsh
+  0.00s user 0.01s system 78% cpu 0.014 total
+  ```
+
+## Usage
+
+Copy your theme to `$ZSH_CUSTOM/themes/` and modify it to add `$(branch_prompt_info)` in your prompt.
+This example is for the `robbyrussell` theme:
+
+```diff
+diff --git a/themes/robbyrussell.zsh-theme b/themes/robbyrussell.zsh-theme
+index 2fd5f2cd..9d89a464 100644
