Update browser-history description

[Samyak2]

Description

browser-history has changed quite a bit since v0.0.1 when it was added here. Specifically the code snippet given on the project's page does not work anymore on the latest release.

A detailed learning path is also missing.

Though a minor issue, there is also no direct link to the project's GitHub page.

Hi, so I am not sure what I should put for a detailed learning path. Could you list the requirements here?

[Samyak2]

I was thinking of sending a PR directly. Is that ok?

[tfidfwastaken]

Yes, although pull in the small changes that I have made to your page now and then do as you please
