 The whole API for interaction with PostgreSQL is performed asynchronously in `Aff`
 (the only function which runs in plain `Effect` is `newPool`). Core library
 functions usually results in somthing like `Aff (Either PGError a)` which can be easily
-wrapped by user into `ExceptT` or any other custom monad stack. To be honest we provides predifined `ExceptT`
-versions of functions in `Database.PostgreSQL.PG` along with some `hoist*` helpers.
+wrapped by user into `ExceptT` or any other custom monad stack.
+To be honest we provide alternatives to functions in the `Database.PostgreSQL.PG` module that work on any stack `m` with `MonadError PGError m` and `MonadAff m`.
+The module contains two functions `withConnection` and `withTransaction` that require additional parameter - a transformation from a custom monad stack to `Aff (Either PGError a)`.
 We are going to work with `PG` type in this tutorial but please don't consider it as the only option
 if you encounter any troubles integrating it into your own app monad stack.

-  type PG a = ExceptT PGError Aff a

+type PG a = ExceptT PGError Aff a

+withConnection :: forall a. Pool -> (Connection -> PG a) -> PG a
+withConnection = PG.withConnection runExceptT

+withTransaction :: forall a. Connection -> PG a -> PG a
+withTransaction = PG.withTransaction runExceptT
+```
 
 We assume here that Postgres is running on a standard local port
 with `ident` authentication so configuration can be nearly empty (`defaultPoolConfiguration`).
