What is it?[edit]

Tabby is "...a terminal for the modern age." You can read more about what Tabby is and isn't here. The vast majority of what you'll be doing on  Coder Merlin™  will involve using a shell that you'll access through a terminal such as Tabby.

General Configuration[edit]

Tabby requires several steps to complete its configuration. Most of these steps need to be performed only once because Tabby stores the configuration remotely (in the Cloud). It's very important to follow the instructions carefully.

GitHub, GitLab, or Google Account Required[edit]

Ensure that you have a GitHub, GitLab, or Google account configured. This is required to log in to Tabby.

Access[edit]

Access Tabby from the "My Tools" menu in the top left of your screen. Then click the "Shell" button. Tabby opens.
