Next steps (a PostgreSQL with the pgvector extension is a prerequisite - not installed for you):
  memnos setup     # enter your Postgres connection - creates the schema + an admin token
  memnos start     # start the server, then open http://127.0.0.1:8900/admin

Every new terminal will have 'memnos' on PATH.
