How to properly structure a repository on GitHub?

Question

git

Hello. I'm just getting started with GitHub. What is the correct way to organize folders/repositories?
Suppose we have an instagram project. Website, applications for mobile phones and API.
Under the project, you need to create an instagram repository and it already has web, android and api subfolders. And in them to throw the corresponding project? Like:
username/instagram/web
username/instagram/android
username/instagram/api
or for each project its own repository, for example instagram-web, instagram-android, instagram-api like:
username/instagram-web
username/instagram-android
username /instagram-api

Answer 1

There are also organizations and projects on GitHub. And BitBucket has everything in beauty - under the Instagram project, it has all the repositories.
