## on Bash
To install the completion, you should either, source the main script on your current terminal or source the main script on your bash configuration.

### Direct use
From ArduPilot root directory, simply use :
```` bash
source ./Tools/completion/completion.bash
````
And now completion works from your terminal instance. If you close the terminal, the completion feature is removed.

### Permanent use
Edit you `.bashrc` file, it is on your Home directory but it is a hidden file (CTRL+H on Ubuntu to reveal them). Then put at the end of the file :
```` bash
source PATH_TO_ARDUPILOT_DIRECTORY/Tools/completion/completion.bash
````
where PATH_TO_ARDUPILOT_DIRECTORY is the path to ArduPilot directory.

### Usage
You can now abuse of your TAB key on `waf` and `sim_vehicle.py` call ! See the video at the end.

## On ZSH
Zsh don't allow live loading of completion. So you have to source the completion script in your `.zshrc` file. Like for Bash, you will find it hiding on your home !
Put at the end of the file :
```` bash
source PATH_TO_ARDUPILOT_DIRECTORY/Tools/completion/completion.zsh
````
where PATH_TO_ARDUPILOT_DIRECTORY is the path to ArduPilot directory. Notice the difference, the extension is `.zsh` !
