 ### Connection pool and timeouts
 The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.

+## `ColumnType` Support
+This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
+
+## `context.Context` Support
+Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
+See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
+

 ### `LOAD DATA LOCAL INFILE` support
 For this feature you need direct access to the package. Therefore you must change the import path (no `_`):

 See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support.

-## `context.Context` Support
-Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
-See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.

 ## Testing / Development
 To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.

+Package cloudsql exposes access to Google Cloud SQL databases.
+
+This package does not work in App Engine "flexible environment".
+
+This package is intended for MySQL drivers to make App Engine-specific
+connections. Applications should use this package through database/sql:
+Select a pure Go MySQL driver that supports this package, and use sql.Open
+with protocol "cloudsql" and an address of the Cloud SQL instance.
+
+A Go MySQL driver that has been tested to work well with Cloud SQL
+is the go-sql-driver:
+	import "database/sql"
+	import _ "github.com/go-sql-driver/mysql"
+
+	db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname")
+
+
+Another driver that works well with Cloud SQL is the mymysql driver:
+	import "database/sql"
+	import _ "github.com/ziutek/mymysql/godrv"
+
+	db, err := sql.Open("mymysql", "cloudsql:instance-name*dbname/user/password")
+
+
+Using either of these drivers, you can perform a standard SQL query.
+This example assumes there is a table named 'users' with
+columns 'first_name' and 'last_name':
+
+	rows, err := db.Query("SELECT first_name, last_name FROM users")
+	if err != nil {
+		log.Errorf(ctx, "db.Query: %v", err)
+	}
+	defer rows.Close()
+
+	for rows.Next() {
+		var firstName string
+		var lastName string
+		if err := rows.Scan(&firstName, &lastName); err != nil {
+			log.Errorf(ctx, "rows.Scan: %v", err)
+			continue
+		}
+		log.Infof(ctx, "First: %v - Last: %v", firstName, lastName)
+	}
+	if err := rows.Err(); err != nil {
+		log.Errorf(ctx, "Row error: %v", err)
+	}

+## Gotchas
+
+### Parallel testing
+
+This library doesn't yet support running tests in parallel! Running tests
+in parallel can result in random data being present in the database, which
+will likely cause tests to randomly/intermittently fail.
+
+This is specially tricky since it's not immediately clear that `go test ./...`
+run tests for each package in parallel. If more than one package use this
+library, you can face this issue. Please, use `go test -p 1 ./...` or run tests
+for each package in separated commands to fix this issue.
+
+See [#40](https://github.com/go-testfixtures/testfixtures/issues/40)
+and [golang/go#11521](https://github.com/golang/go/issues/11521) for more information.
+
+We're also planning to implement transactional tests to allow running tests
+in parallel (see [#24](https://github.com/go-testfixtures/testfixtures/issues/24)).
+Running each test package in a separated database would also allow you to do that.
+Open issues for other ideas :slightly_smiling_face:.
