+# Mercurial plugin
+
+This plugin adds some handy aliases for using Mercurial as well as a few
+utility and prompt functions that can be used in a theme.
+
+To use it, add `mercurial` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... mercurial)
+```
+

+## Prompt usage
+
+- Switch to a theme which uses `hg_prompt_info`
+
+- Or customize the `$PROMPT` variable of your current theme to contain current folder mercurial repo info.
+  This can be done by putting a custom version of the theme in `$ZSH_CUSTOM` or by changing `$PROMPT` in
+  `.zshrc` after loading the theme.
+
+  For example, for the `robbyrussell` theme you need to modify `$PROMPT` var by adding `$(hg_prompt_info)`
+  after `$(git_prompt_info)`, so it looks like this:
+
+  ```zsh
+  PROMPT='${ret_status}%{$fg_bold[green]%}%p %{$fg[cyan]%}%c %{$fg_bold[blue]%}$(git_prompt_info)$(hg_prompt_info)%{$fg_bold[blue]%} % %{$reset_color%}'
+  ```
+
+You can also redefine additional vars used in the plugin (after Oh My Zsh is sourced):
+
+```zsh
+ZSH_THEME_HG_PROMPT_PREFIX="%{$fg_bold[magenta]%}hg:(%{$fg[red]%}"
+ZSH_THEME_HG_PROMPT_SUFFIX="%{$reset_color%}"
+ZSH_THEME_HG_PROMPT_DIRTY="%{$fg[magenta]%}) %{$fg[yellow]%}✗%{$reset_color%}"
+ZSH_THEME_HG_PROMPT_CLEAN="%{$fg[magenta]%})"
+```
+
+### Display repo branch and directory status in prompt
+
+This is the same as git plugin does. **Note**: additional changes to `.zshrc`, or using a theme designed
+to use `hg_prompt_info`, are required in order for this to work.
