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 the use of a shell, which 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 only be performed once because Tabby will store 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 in order to log in to Tabby.
