Welcome to the community forums.
I guess the best way to start is to ask and try to help into the forums. (So... you are on the right path)
Normally I could say that you can find a lot of information on StackExchange and also that you can start diving into the http://devdocs.magento.com/
But your question is a little bit different.
I guess the first answer could be another question: which kind of project?
Magento is a powerfull and well known ecommerce platform and is ultra-flexible. The plasticity of the platform is huge but is a better idea to use the right tool for the right job.
Can you share a liitle bit more about your project?
