 ## First Run
 
-> You'll need to create the first invitation to invite yourself.
-
 1. Open a terminal in VSCode.
 2. Run `pnpm dev` to start the server in development mode.
-3. Go to `http://localhost:3000/`, you should see there are 0 courses, 0 posts, and 1 user.
-4. Go to `http://localhost:7474/`, which is the database management interface.
-5. Login as `neo4j` with password `password`.

+3. Go to `http://localhost:5173/`, you should see there are 0 courses, 0 posts, and 1 user.
+4. You should also see a panel with title "Welcome aboard", this panel only appears for your first account (specifically, if these only 1 user in DB).
+5. Get started with entering usernames and roles, then you would be navigated to register page to complete the account information.
+6. Voilà, your first account is ready!
 
-```cypher
-MATCH (x:User {username: "admin"}) MERGE (x)<-[:OWNED_BY]-(invitation:Invitation { code: "first_code", created: datetime(), revoked: false })

+In case the above approach doesn't work, you can follow these instructions to create your account in DB.

+4. Then, you can use the invitation code to register your account in the realm website.
+5. Next, you can give yourself roles `Verified`, `CoursePacker`, `Moderator` by running queries like:
 
 ```cypher
 MATCH (u:User {username: "your_username"}) SET u:Verified
