If I develop a module and use 3rd party code in it, is there a place to display the required licenses? or an EULA for the module?
Yeah, there’s a element that you can include in your module.xml which will be displayed (and agreed to) when someone installs the module.
Ninja edit: contents of said element should be the name of an html file you’ve included in the modl file, e.g. license.html
