Banged my head against Tachidesk for a bit tonight, I do not see how to import sources, even a local one, I guess there is more hidden config stuff to do.
I do not see how to import sources
You need to install extensions before you can use the source section to perform a search. Once you’ve done that, typing something into the search field under sources will search through all the extensions you have installed.
even a local one
They have an entire guide on that.
