Need a Getting Started page

[kelle]

need text (either on front page or on new standalone page) which explains how to use the site.

• use "Interactive Tutorial Notebook" to work on notebook in the cloud
• download to work on your own computer. need instructions on how to run the notebook.
• how to use tags on the left
• how search works?

If they download locally, they need to also install all the things, right? WHere as Binder will setup the environment based on requirements.txt? We should explain this somewhere.

[kelle]

also recommend 1-3 tutorials that would be the best to start with if you are really starting from the beginning. (python: beginner and astro:beginner)

I would like to work on this if no one else has expressed interest
