In GitHub, what is the conceptual difference between a project (that can be created inside a repository) and a repository?
I've seen several similar questions (here, here and here) in SO, but none of them explains what is a GitHub project, what is a GitHub repository and when to use each one of them.
I would appreciate if someone can explain each term, and provide an example of when to use/create each one. For instance, if I have several prototype applications, all independent of each other, what do I create in order to manage in an organized way the source code for all of them?
GitHub recently introduced a new feature called Projects. This provides a visual board that is typical of many Project Management tools:
A Repository as documented on GitHub:
A repository is the most basic element of GitHub. They're easiest to imagine as a project's folder. A repository contains all of the project files (including documentation), and stores each file's revision history. Repositories can have multiple collaborators and can be either public or private.
Part of the confusion is that the new feature, Projects, conflicts with the overloaded usage of the term project in the documentation above.
