Hi.
Follow the instruction:
When i write :"git clone https://github.com/zerojay/RetroPie-Extra.git"
i'm asked for username and password,
what username and password. ? (pi and raspberry doesn't work)

@ponior Do you have a github account configured on the system or a ssh key/passphrase ? You can download the repository as a zip file from the github page if you're unable to run the 'clone' operation.

@ponior If you just want a web browser, follow the docs to install the Pixel desktop, then install Chromium to have a web browser once you start your desktop session.
