I’ve had Sublime Text (ST) 2 installed now for quite a while, purely because I use the Cypher highlighting package, and whilst I waited for ST3 to have it in the Package manager, it didn’t matter that I had both for a while. But I finally decided to bite the bullet and install Cypher manually into ST3.
Step 1.
Go to https://github.com/kollhof/sublime-cypher and Download ZIP of the repo.
Step 2.
Open ST3, and go to ‘Browse Packages’ (CTRL+SHIFT+P then type ‘browse’)
Step 3.
In the Explorer window, add a new folder called ‘Cypher’
Step 4.
Extract the contents of the ZIP you downloaded in Step 1 into the folder you created in Step 3
Step 5.
Restart ST3.
Step 6.
Switch to Cypher mode (CTRL+SHIFT+P then ‘Cypher’)
Step 7.

Ha! We all know that won’t work :)
