I challenged myself to try and post something on here before 2020 was over. This is not an exciting update but I finally got round to using Atom as an editor again. I was able to link to my GIthub account and update some repos as a test.
After a bad experience with Atom over two years ago I decided to try again as it's become much more popular of late.
After I rushed things and couldn't get it working I then used this excellent tutorial to get back on track – https://www.youtube.com/watch?v=6HsZMl-qV5k.
I will now try to use it as my main editor to get used to it for various projects.
