We need to get an upgrade video going soon...
But.. you can see the version from inside Admin Settings
If you’ve made an customisation you’ll need to bear them n mind but you have two options: manual or auto updates.
There’s more info on those in the manual and what files to keep an eye on and here:
Always back up before updating!
As long as you keep the /content and /template and config.json file safe it should be easy and smooth
Please let us know how you go!
