At my current customer we use Github a lot. Everything requires a review via a Pull Request. It is sometimes tedious to switch from your IDE or terminal to the browser while creating a PR. Github has a command line utility called gh which you can use to automatically create a PR from the command line. It has lots of extra stuff as well, such as downloading releases, viewing issues, creating gists, cloning repo’s and code completion.

Start by following the installation steps in https://github.com/cli/cli to install the gh binary. There are packages for all operating systems.
