How to add words to Atom's spell checker dictionary?

Question

Trying to get a bit more functionality out of Atom\'s spell checker and right now the false positives are making it less than useful.

How can I add a word to Atom\'s dic

Answer 1

Flávio Camilo's solution works for me.

I'm using Atom 1.15.0 on debian jessie (8.7) in xfce4 (4.10.1) 'ctrl+shift+:' opens the list of suggested corrections. The last entry 'Add to Known Words' appears when it is enabled on the plugin settings. In main menu 'Edit -> Preferences -> Packages' search for 'spell-check' (i'm seeing version 0.70.2) click on 'settings' search the checkbox on item 'Add Known Words', enable it and restart atom.

NOTE: I needed to do this twice, on the first restart the 'tick' on 'Add Known Words' was lost somehow.
