 You can use the above aliases as `--user` by using the prefix `scu` instead of `sc`.
 For example: `scu-list-units` will be aliased to `systemctl --user list-units`.
+
+### Unit Status Prompt
+
+You can add a token to your prompt in a similar way to the gitfast plugin. To add the token
+to your prompt, drop `$(systemd_prompt_info [unit]...)` into your prompt (more than one unit
+may be specified).
+
+The plugin will add the following to your prompt for each `$unit`.
+```
+<prefix><unit>:<active|notactive><suffix>
+```
+You can control these parts with the following variables:
+
+- `<prefix>`: Set `$ZSH_THEME_SYSTEMD_PROMPT_PREFIX`.
+
+- `<suffix>`: Set `$ZSH_THEME_SYSTEMD_PROMPT_SUFFIX`.
+
+- `<unit>`: name passed as parameter to the function. If you want it to be in ALL CAPS,
+  you can set the variable `$ZSH_THEME_SYSTEMD_PROMPT_CAPS` to a non-empty string.
+
+- `<active>`: shown if the systemd unit is active.
+  Set `$ZSH_THEME_SYSTEMD_PROMPT_ACTIVE`.
+
+- `<notactive>`: shown if the systemd unit is *not* active.
+  Set `$ZSH_THEME_SYSTEMD_PROMPT_NOTACTIVE`.
+
+For example, if your prompt contains `PROMPT='$(systemd_prompt_info dhcpd httpd)'` and you set the following variables:
+
+```
+ZSH_THEME_SYSTEMD_PROMPT_PREFIX="["
+ZSH_THEME_SYSTEMD_PROMPT_SUFFIX="]"
+ZSH_THEME_SYSTEMD_PROMPT_ACTIVE="+"
+ZSH_THEME_SYSTEMD_PROMPT_NOTACTIVE="X"
+ZSH_THEME_SYSTEMD_PROMPT_CAPS=1
+```
+
+If `dhcpd` is running, and `httpd` is not, then your prompt will look like this:
+
+```
+[DHCPD: +][HTTPD: X]
+```
