+[CrateDB] is compatible with PostgreSQL, so its dbt adapter strongly depends on
+dbt-postgres, documented at [Postgres profile setup].
+
+CrateDB targets are configured exactly the same way, with just a few things to
+consider which are special to CrateDB. Relevant details are outlined at [using
+dbt with CrateDB], which also includes up-to-date information.
+
+
+## Profile configuration
+
+CrateDB targets should be set up using a configuration like this minimal sample
+of settings in your [`profiles.yml`] file.
+
+<File name='~/.dbt/profiles.yml'>
+
+```yaml
+cratedb_analytics:
+  target: dev
+  outputs:
+    dev:
+      type: cratedb
+      host: [clustername].aks1.westeurope.azure.cratedb.net
+      port: 5432
+      user: [username]
+      pass: [password]
+      dbname: crate         # Do not change this value. CrateDB's only catalog is `crate`.
+      schema: doc           # Define the schema name. CrateDB's default schema is `doc`.
+```
