In order to download a file from the web to your project, type the following command into your terminal:

wget http://url-to-your-file.something

This command will download this file into your project and the file should appear in your file explorer as soon as downloading finishes.

Unzipping a downloaded zip

If you downloaded a zip archive (e.g. a zipped HTML template that you would like to use for your project), run the following command in the terminal

unzip name-of-your-file.zip

This will export all contents of the zip archive and make them available to your file explorer as soon as unzipping finishes.
