I want to use Orchard Core as my CMS, but I can't find any good write ups on how to take an existing theme and tweak it. I know if I download the source code I can just overwrite an existing project, or copy/paste one and tweak that but that seems messy when I can install Orchard Core as a nuget package. I'll keep my notes here as I go along.
Here's what I've done so far
dotnet new octheme -n "ZachsBlogTheme"(you need to install the orchard command line tools to do this)
That should do it. I ran into an issue where it seemed like my custom Orchard Core theme wasn't loading any css, but that was because I didn't overwrite existing files when I copied in TheBlogTheme so the main layout file for the theme was missing. Silly mistake but documenting it here in case someone else runs into it.
