I am following the guide [Protecting a Blog Application](https://authzed.com/docs/spicedb/getting-started/protecting-a-blog) after installing Zed and SpiceDb on Debian. The instruction is not clear to me and I am failling at the Prerequisites.

One of:
 - An Authzed Permission System and associated API Token with admin access
 - A running instance of SpiceDB with the configured preshared key for SpiceDB

I just have a fresh SpiceDB, how do I get a token and I don't even know how to have a running instance of the db?
