Usually the code on a project is stored in some repository, like github, but usually a lot of stuff is not stored in the github for a project.
For example, in order to create your project you need to have a compiler, libraries, modules, tools, etc.
Most of them are usually available on the net but ... but there are some limits.
What happens if you want to build your project in the future ?
How can you be sure to be able to find what "now" is easily available ?
