Suggestions: add 'sudo apt install textql' and simple text examples

[falconair]

Hi, a couple of suggestions.
It looks like on ubuntu, textql is easily installable via 'sudo apt install textql' Why not list that on the main page, next to 'brew install textql'?

Also, the animated gif is great, but a couple of simple select statements will be extremely helpful to people who just want to do a quick job with this.
