Depending on how the course has been set up, you will either be using remotely installed sites (e.g. on the GovCMS Lagoon platform), or you’re using a local installation (on your computer). If you’re working locally, we recommend using the GovCMS8 bundled development environment at: https://github.com/govcms/govcms8-scaffold. A complete guide for installation is available at https://github.com/govCMS/govcms8-scaffold/blob/master/README.md
You’ll also need a web browser with an inspection tool (e.g. Firebug or Firefox) - you can download Firebug here: http://getfirebug.com. You can also use Chrome’s “Developer tools” or Safari’s “Develop menu”.
