Hi there!

this will eventually show a bunch of resources, that are free and open-source, that people can use to learn new different languages at their own pace and time, and look through resources related to code golfing, ...

there should be a general language learning path with the basics e.g.: "if-else" ..., as well as language specific paths

ideally, there are several levels of understanding, one that just says enough to get going with X (explained in a very rudimentary way, so anyone can understand), then another that goes a more in depth on how X works ...
So basically 3 levels, that expect a user to have a different understanding of the language, and each tailored to how much the person would like to know and understand
