 :::{rubric} Protocol Support
 :::
 CrateDB supports both the HTTP protocol and the PostgreSQL wire protocol,
 which ensures that many clients that work with PostgreSQL, will also work with
-CrateDB. Through corresponding drivers, CrateDB is compatible with ODBC,
+CrateDB.
+
+Through corresponding drivers, CrateDB is compatible with ODBC,
 JDBC, and other database API specifications. By supporting SQL, CrateDB is
 compatible with many standard database environments out of the box.
 
+The HTTP protocol can be used to connect from environments where
+PostgreSQL-based communication is not applicable.
+
+:::{rubric} Notes
+:::
 While it is generally recommended to use the PostgreSQL interface (PG) for maximum
 compatibility in PostgreSQL environments, the HTTP interface supports CrateDB
 bulk operations and BLOBs, which are not supported by the PostgreSQL
 protocol.
