hi after i installed discourse in my own host i need some theme i ask if there’s for free and if not how i build one
You can browse for various free themes and theme components in the #plugin:theme category.
Asking how to build one on your own is a very broad question. I’d suggest using the search to find as many answers as you can, then for whatever you are still trying to figure out, you may want to list the specific aspects of Discourse that you would like to learn how to customize and change.
If it becomes too large in scope for people to give you suggestions, you could always post in #marketplace for a paid solution.
thank you man
