-Usage

+# Usage
 
 Jet requires already defined database schema(with tables, enums etc), so that jet generator can generate SQL Builder
 and Model files. File generation is very fast, and can be added as every pre-build step.
 Sample command:
+
 	jet -dsn=postgresql://user:pass@localhost:5432/jetdb -schema=dvds -path=./.gen
 
 Before we can write SQL queries in Go, we need to import generated SQL builder and model types:
+
 	import . "some_path/.gen/jetdb/dvds/table"
 	import "some_path/.gen/jetdb/dvds/model"
 
 To write postgres SQL queries we import:
+
 	. "github.com/go-jet/jet/v2/postgres" // Dot import is used so that Go code resemble as much as native SQL. It is not mandatory.
 
 Then we can write the SQL query:
+
 	// sub-query
 	rRatingFilms :=
 		SELECT(

 We can print a statement to see SQL query and arguments sent to postgres server:
