-Package jet is a framework for writing type-safe SQL queries in Go, with ability to easily convert database query
-result into desired arbitrary object structure.
+Package jet is a complete solution for efficient and high performance database access, consisting of type-safe SQL builder
+with code generation and automatic query result data mapping.
+Jet currently supports PostgreSQL, MySQL, MariaDB and SQLite. Future releases will add support for additional databases.
 
 
 Installation
 
 
-Use the bellow command to add jet as a dependency into go.mod project:
-	$ go get github.com/go-jet/jet/v2
+Use the command bellow to add jet as a dependency into go.mod project:
+	$ go get -u github.com/go-jet/jet/v2
 
-Use the bellow command to add jet as a dependency into GOPATH project:
-	$ go get -u github.com/go-jet/jet
+Jet generator can be installed in one of the following ways:
 
-Install jet generator to GOPATH bin folder. This will allow generating jet files from the command line.
-	cd $GOPATH/src/ && GO111MODULE=off go get -u github.com/go-jet/jet/cmd/jet
+	1) (Go1.16+) Install jet generator using go install:
+		go install github.com/go-jet/jet/v2/cmd/jet@latest
+
+	2) Install jet generator to GOPATH/bin folder:
+		cd $GOPATH/src/ && GO111MODULE=off go get -u github.com/go-jet/jet/cmd/jet
+
+	3) Install jet generator into specific folder:
+		git clone https://github.com/go-jet/jet.git
+		cd jet && go build -o dir_path ./cmd/jet
+
+Make sure that the destination folder is added to the PATH environment variable.
 
-Make sure GOPATH bin folder is added to the PATH environment variable.
 
 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 -source=PostgreSQL -host=localhost -port=5432 -user=jet -password=pass -dbname=jetdb -schema=dvds -path=./gen
+	jet -dsn=postgresql://user:pass@localhost:5432/jetdb -schema=dvds -path=./.gen
 
-Then next step is to import generated SQL Builder and Model files and write SQL queries in Go:
+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 SQL queries for PostgreSQL import:
-	. "github.com/go-jet/jet/v2/postgres"
+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.
 
-To write SQL queries for MySQL and MariaDB import:
-	. "github.com/go-jet/jet/v2/mysql"
-*Dot import is used so that Go code resemble as much as native SQL. Dot import is not mandatory.
-
-Write SQL:
+Then we can write the SQL query:
 	// sub-query
-	rRatingFilms := SELECT(
-				Film.FilmID,
-				Film.Title,
-				Film.Rating,
-			).
-			FROM(Film).
-			WHERE(Film.Rating.EQ(enum.FilmRating.R)).
-			AsTable("rFilms")
+	rRatingFilms :=
+		SELECT(
+			Film.FilmID,
+			Film.Title,
+			Film.Rating,
+		).FROM(
+			Film,
+		).WHERE(
+			Film.Rating.EQ(enum.FilmRating.R),
+		).AsTable("rFilms")
 
 	// export column from sub-query
 	rFilmID := Film.FilmID.From(rRatingFilms)
 
 	// main-query
-	query := SELECT(
+	stmt :=
+		SELECT(
 			Actor.AllColumns,
 			FilmActor.AllColumns,
 			rRatingFilms.AllColumns(),
-		).
-		FROM(
+		).FROM(
 			rRatingFilms.
-			INNER_JOIN(FilmActor, FilmActor.FilmID.EQ(rFilmID)).
-			INNER_JOIN(Actor, Actor.ActorID.EQ(FilmActor.ActorID)
-		).
-		ORDER_BY(rFilmID, Actor.ActorID)
+				INNER_JOIN(FilmActor, FilmActor.FilmID.EQ(rFilmID)).
+				INNER_JOIN(Actor, Actor.ActorID.EQ(FilmActor.ActorID)
+		).ORDER_BY(
+			rFilmID,
+			Actor.ActorID,
+		)
 
-Store result into desired destination:
+Now we can run the statement and store the result into desired destination:
 	var dest []struct {
 		model.Film
 
 		Actors []model.Actor
 	}
 
-	err := query.Query(db, &dest)
+	err := stmt.Query(db, &dest)
 
-Detail info about all features and use cases can be
+We can print a statement to see SQL query and arguments sent to postgres server:
+	fmt.Println(stmt.Sql())
+
+Output:
+	SELECT "rFilms"."film.film_id" AS "film.film_id",
+		 "rFilms"."film.title" AS "film.title",
+		 "rFilms"."film.rating" AS "film.rating",
+		 actor.actor_id AS "actor.actor_id",

+# Integration tests
+
+This folder contains integration tests intended to test jet generator, statements and query result mapping with a running database.
+
+## How to run tests?
+
+Before we can run tests, we need to set up and initialize test databases.
+To simplify the process there is a Makefile with a list of helper commands.
+```shell
+# We first need to checkout testdata from separate repository into git submodule,
+# then download docker image for each of the databases listed in docker-compose.yaml file, and 
+# finally run and initialize databases with downloaded test data.
+# Note that on the first run this command might take a couple of minutes.
+make setup
+
+# When databases are ready, we can generate sql builder and model types for each of the test databases
+make jet-gen-all
+```
+
+Then we can run the tests the usual way:
+```shell
+go test -v ./...
+```
+
+To removes test containers, volumes, and images:
+```shell
+make cleanup
+```
