I have an open source project (under GPL license) that has some parts incorporated from other projects (that use MIT and GPL), and one of the provisions of both of these licenses is
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software or something along those lines. However, I can't find any clear information on how to acknowledge copyright holders in my project on repository hosting sites like GitHub or elsewhere. Should I make a file and 'copypaste' these notices there?
I also read somewhere that notices are no longer obligatory under Berne Convention (at least in countries that are signatories to the convention), but despite this I still want to properly acknowledge other's work I've used in my own project.
