+Download the current completions file for your shell from qsv's source code at [`contrib/completions/examples`](https://github.com/dathere/qsv/blob/master/contrib/completions/examples).
 
 For example to enable the Bash completions:
 
 1. Run `source qsv.bash` to enable the completions in your current terminal instance (or replace `qsv.bash` to the path to it if not in your current working directory).
 2. You may also move `qsv.bash` to your home directory (`~/qsv.bash`) and also create a `.bashrc` file in your home directory (`~/.bashrc`) to include `source qsv.bash` as a line within it for the completions script to run whenever you launch a bash terminal.

 If you're unfamiliar with qsv then don't worry. The initial exercises are intended for beginners that haven't tried qsv yet. We'll explore multiple features qsv has to offer while solving problems you may find in real-world scenarios. You may learn to use qsv in an interactive way by practicing exercises to resolve data wrangling issues.
