Invite Ptarmigan
Ptarmigan can be added in two different ways: to your server or to your account. Adding it to your account allows you to use its commands anywhere (servers, direct messages) but the list of commands is reduced.
1. Invite Ptarmigan to a server
To invite Ptarmigan to a server, you must have the "Manage Server" permission on it. Then, click on this link: https://ptarmigan.xyz/invite, then on "Add to Server" and select your server from the list that will be displayed.
2. Invite Ptarmigan to your account
It's possible to invite Ptarmigan to your account to have access to its commands in all servers, and also in direct messages with other users. It's important to note that not all of Ptarmigan's commands and features are available on the account. Some commands are only available when Ptarmigan is present on the server where you execute the command.
