 This provider allows to manage with Terraform [Postgresql](https://www.postgresql.org/) objects like databases, extensions, roles, etc..
 
-It's published on the [Terraform registry](https://registry.terraform.io/providers/cyrilgdn/postgresql/latest/docs).
-It replaces https://github.com/hashicorp/terraform-provider-postgresql since Hashicorp stopped hosting community providers in favor of the Terraform registry.
+It's an extension of [Terraform registry](https://registry.terraform.io/providers/cyrilgdn/postgresql/latest/docs).
 
 - Documentation: https://registry.terraform.io/providers/cyrilgdn/postgresql/latest/docs
-
-Requirements
-------------
-
--	[Terraform](https://www.terraform.io/downloads.html) 0.12.x
--	[Go](https://golang.org/doc/install) 1.16 (to build the provider plugin)
-
-Building The Provider
----------------------
-
-Clone repository to: `$GOPATH/src/github.com/cyrilgdn/terraform-provider-postgresql`
-
-```sh
-$ mkdir -p $GOPATH/src/github.com/cyrilgdn; cd $GOPATH/src/github.com/cyrilgdn
-$ git clone git@github.com:cyrilgdn/terraform-provider-postgresql
-```
-
-Enter the provider directory and build the provider
-
-```sh
-$ cd $GOPATH/src/github.com/cyrilgdn/terraform-provider-postgresql
-$ make build
-```
-
-Using the provider
-----------------------
-
-Usage examples can be found in the Terraform [provider documentation](https://www.terraform.io/docs/providers/postgresql/index.html)
-
-Developing the Provider
----------------------------
-
-If you wish to work on the provider, you'll first need [Go](http://www.golang.org) installed on your machine (version 1.11+ is *required*). You'll also need to correctly setup a [GOPATH](http://golang.org/doc/code.html#GOPATH), as well as adding `$GOPATH/bin` to your `$PATH`.
-
-To compile the provider, run `make build`. This will build the provider and put the provider binary in the `$GOPATH/bin` directory.
-
-```sh
-$ make build
-...
-$ $GOPATH/bin/terraform-provider-postgresql
-...
-```
-
-In order to test the provider, you can simply run `make test`.
-
-```sh
-$ make test
-```
-
-In order to run the full suite of Acceptance tests, run `make testacc`.
-
-*Note:* 
-- Acceptance tests create real resources, and often cost money to run.
-
-```sh
-$ make testacc
-```
-
-In order to manually run some Acceptance test locally, run the following commands:
-```sh
-# spins up a local docker postgres container
-make testacc_setup 
-
-# Load the needed environment variables for the tests
-source tests/switch_superuser.sh
-
-# Run the test(s) that you're working on as often as you want
-TF_LOG=INFO go test -v ./postgresql -run ^TestAccPostgresqlRole_Basic$
-
-# cleans the env and tears down the postgres container
-make testacc_cleanup 
-```
