+Once I faced with an issue to change our corporate migrations library in Golang from [rubenv/sql-migrate](https://github.com/rubenv/sql-migrate)
 to [golang-migrate](https://github.com/golang-migrate) and it was so hard.
 There are several caveats that you should know about, so it can save you some time:
  - You have to split each sql-migrate file in 2 files: up and down migration.
- - By default migrations in sql-migrate are running in transaction-default mode, but in golang-migrate you have to wrap it in BEGIN;COMMIT; for transactions.
+ - By default, migrations in sql-migrate are running in transaction-default mode, but in golang-migrate you have to wrap it in BEGIN;COMMIT; for transactions.
  - Golang-migrate [doesn't like](https://github.com/golang-migrate/migrate/issues/731) the same timestamp for different files.
  - You [can't](https://github.com/golang-migrate/migrate/issues/284) create several indexes concurrently without adding x-multi-statement=true flag for DB connection. 
 However, please note that this flag [will break](https://github.com/golang-migrate/migrate/issues/590) your CREATE FUNCTION ... AS $$ symbol.
