+# VirtualBox plugin
+
+The `virtualbox` plugin provides many useful aliases for VirtualBox.
+
+To use it, add `virtualbox` to the plugins array of your `.zshrc` file:
+
+```zsh
+plugins=(... virtualbox)
+```
+
+## Aliases

+
+The prefix for the aliases can be customised by setting `ZSH_PLUGIN_VIRTUALBOX_ALIAS_PREFIX` (default: `vbox`).
+
+## Status prompt
+
+Add `$(virtualbox_prompt_info [vm_name] ...)` to your prompt to show the status
+of all specified virtual machines.
+
+The plugin will add the following to your prompt for each `$vm_name`.
+
+```text
+<prefix><vm_name>:<running|notrunning><suffix>
+```
+
+You can control these parts with the following variables:
+
+- `<prefix>`: Set `$ZSH_THEME_VIRTUALBOX_PROMPT_PREFIX`.
+
+- `<suffix>`: Set `$ZSH_THEME_VIRTUALBOX_PROMPT_SUFFIX`.
+
+- `<vm_name>`: name passed as parameter to the function. If you want it to be in ALL CAPS,
+  you can set the variable `$ZSH_THEME_VIRTUALBOX_PROMPT_CAPS` to a non-empty string.
+
+- `<running>`: shown if the virtual machine is running.
+  Set `$ZSH_THEME_VIRTUALBOX_PROMPT_RUNNING`.
+
+- `<notrunning>`: shown if the virtual machine is *not* running.
+  Set `$ZSH_THEME_VIRTUALBOX_PROMPT_NOTRUNNING`.
+
+You can set `ZSH_THEME_VIRTUALBOX_PROMPT_COUNT` to a non-empty string to show a
+count of running virtual machines / total.
+
+For example, if your prompt contains `PROMPT='$(virtualbox_prompt_info "Arch Linux" "Debian")'`
+and you set the following variables:
+
+```sh
+ZSH_THEME_VIRTUALBOX_PROMPT_COUNT="true"
+ZSH_THEME_VIRTUALBOX_PROMPT_PREFIX="["
+ZSH_THEME_VIRTUALBOX_PROMPT_SUFFIX="]"
+ZSH_THEME_VIRTUALBOX_PROMPT_RUNNING="+"
+ZSH_THEME_VIRTUALBOX_PROMPT_NOTRUNNING="X"
+ZSH_THEME_VIRTUALBOX_PROMPT_CAPS="true"
+```
+
+If `Arch Linux` is running, and `Debian` is not, then your prompt will look like this:
+
+```text
+[1 / 2][ARCH LINUX: +][DEBIAN: X]
+```
