Are there any guides or documents for creating a basic plugin? I still cannot manage to update or change anything outside of CSS and it’s driving me crazy - all I want to be able to do is to affect a few basic things and the only way I seem to be able to change anything gets overridden on a rebuild (which makes sense).
There are no up to date guides unfortunately. It’s something I hope I have time to improve soon.
In the meantime the best thing you can do is dissect an existing plugin. The discourse-tagging plugin is one of our most recent and does a lot of complicated stuff.
That is far too complex an example to use as a learning guide sadly
As an administrator, you can go to the
admin/customize/css_html section and add any HTML/CSS you need
