+# run0
+
+Easily prefix your current or previous commands with `run0` by pressing <kbd>esc</kbd> twice.
+
+To use it, add `run0` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... run0)
+```
+
+## Usage
+
+### Current typed commands
+
+Say you have typed a long command and forgot to add `run0` in front:
+
+```console
+$ apt-get install build-essential
+```
+
+By pressing the <kbd>esc</kbd> key twice, you will have the same command with `run0` prefixed without typing:
+
+```console
+$ run0 apt-get install build-essential
+```
+
+### Previous executed commands
+
+Say you want to delete a system file and denied:
+
+```console
+$ rm some-system-file.txt
+-su: some-system-file.txt: Permission denied
+$
+```
+
+By pressing the <kbd>esc</kbd> key twice, you will have the same command with `run0` prefixed without typing:
+
+```console
+$ rm some-system-file.txt
+-su: some-system-file.txt: Permission denied
+$ run0 rm some-system-file.txt
+Password:
+$
+```
+
+The same happens for file editing, as told before.
+
+## Key binding
+
+By default, the `run0` plugin uses <kbd>Esc</kbd><kbd>Esc</kbd> as the trigger.
+If you want to change it, you can use the `bindkey` command to bind it to a different key:
+
+```sh
+bindkey -M emacs '<seq>' run0-command-line
+bindkey -M vicmd '<seq>' run0-command-line
+bindkey -M viins '<seq>' run0-command-line
+```
+
+where `<seq>` is the sequence you want to use. You can find the keyboard sequence
+by running `cat` and pressing the keyboard combination you want to use.
