Please updating the readme.md

Expected behavior

The 'get started - Installation' shall mentions that, go-vncdriver should be compiled and installed manually to make Universe work (at least for 'Your First Agent').
The reason is that 'go-vncdriver' provided by pip repo does not gurantee openGL support which is required by Universe.

I met this problem and search it in the issues, finally found some clues about the solution.

This problem deserves some words in the main page, I think.

Actual behavior

Nothing about 'go-vncdriver' is mentioned in readme.md.

OpenGL support isn't required, and most users I know don't use it. If you want to watch VNC environments running live, it's much better to point your browser to the URL it gives (such as http://localhost:15900/).

I'm seeing the same issue.

Error: /private/var/folders/fp/628sz3z530q881r3q1r7xbym0000gn/T/pip-build-Eu8vHP/go-vncdriver/.build/src/github.com/openai/go-vncdriver/main.go:387: go_vncdriver was installed without OpenGL support. See https://github.com/openai/go-vncdriver for details on how debug.

Did you see https://github.com/openai/go-vncdriver for details on how debug?

[rogaha]

@tlbtlbtlb yep! I had to build and re-install it locally in order to fix the issue above. I think it would be helpful to update the docs. I'll submit a PR later tomorrow.
