Getting Started with Misskey
Misskey is a program and a project. The server running Misskey, which is open to the public on the Internet, is called an instance. To use Misskey, you need to create an account in one of the instances and use that instance.
You can select an instance of your choice from the instance list.
No matter which instance you choose, you will be able to interact with users on other instances.
Misskey has the ability to federate.
Misskey has built-in federation support, which allows users in different instances to follow, react, and renote in the same way as users on the same instance.
Misskey's federation is based on an open common standard called ActivityPub, and is compatible with other software such as Mastodon and Pleroma.
Choosing an Instance
Some instances may have a specific theme, for example, "I like certain stuff and activities". It is recommended to find an instance of the theme that suits you best.
