+### Compiling modules
 
 The Zsh modules provided by the plugin will build automatically (`hiredis` library is needed). You can
 start more than 1 shell, only the first one will be compiling. If a developer commits a new timestamp to
 `module/RECOMPILE_REQUEST`, the module will recompile (don't worry, at startup, `mtime` is checked
 first, so check for recompilation is fast). I do this when I add tested features or fixes. You can
 recompile the modules yourself by invoking Zsh function `zredis_compile`.
