Contributing to Metamask

Hi,

I am working on a task which includes modifying the metamask plugin, as for working on the code I was wondering is there a slack or such, where I could ask technical questions with regards to metamask internals or get anything clarified on questions I might have while developing on metamask internals.

Currently, the immediate burning question I have is what IDE is usually used for working on metamask, at the moment I am using VSCodes but it does not seem to detect references.
