Hello,
Following the guides in the documentation, I’ve tried my hand at packaging an app locally for testing. I did whatever edits I think were needed in the install scripts and manifest, and I changed the url in the “app.src” file.
It means a path to a folder containing all the apps files (so the manifest.json, scripts folder, etc…)
Typically you can imagine something like :
git clone https://link/to/some/package
# this creates a local folder, let's call it "package"
# ... then you edit the various scripts and files the way you want
# and test it with :
yunohost app install ./package
