What do you want us to do?
Pop round and visit your boss? Give you a project to get started on?
You are a junior programmer: right at the bottom of the totem pole. Your boss is probably busy, and while it seems rude - and it is - to ignore you and sit your there with nothing to do, they have given you a task: learning about the technology you will presumably be using while they sort out all the other stuff.

I prioritise learning and knowledge growth above all.
So do that: learn. They have told you to read up - so get started. Find out what tools you would need to install to actually get started learning the project, make a list and ask for permission to install them yourself so you can practice what you have learned so far. You've been there less than a week and you think you have learned the new stuff so well you don't need to do it any more? I'm betting not...
Just whining about it on a random website is not exactly a good look!
