Readme needs some LUV

[gnunicorn]

The readme is very short and barebone at the moment. It should be expanded and explain in more detail. I see the following sections as useful:

• Screenshot / example code and example rendering
• cargo install-command
• how to use / cli params
• License section

[redoxeon]

I could help out with this :)

[gnunicorn]

@redoxeon very much welcomed. Yes do the changes and raise a PR!

I am not even certain what I am expected to improve beyond what is said above having additional things said above. Maybe the standard-readme spec has some inspiration 🤔 ?!?

[redoxeon]

oh yeah, the standard-readme spec has some good stuff. I'll add whatever I can and see if I can get a good screenshot added in
