-Requirements
-------------
-
+## Requirements
 -	[Terraform](https://www.terraform.io/downloads.html) 0.12.x
 -	[Go](https://golang.org/doc/install) 1.15.x (to build the provider plugin)
 
-Building The Provider
----------------------
-
-Clone repository to: `$GOPATH/src/github.com/terraform-providers/terraform-provider-docker`
+## Building The Provider
 
 ```sh
-$ mkdir -p $GOPATH/src/github.com/terraform-providers; cd $GOPATH/src/github.com/terraform-providers
 $ git clone git@github.com:terraform-providers/terraform-provider-docker
-```
-
-Enter the provider directory and build the provider
-
-```sh
-$ cd $GOPATH/src/github.com/terraform-providers/terraform-provider-docker
 $ make build
 ```
 
-Using the provider
-----------------------
-## Fill in for each provider
-
-Developing the Provider
----------------------------
-
-If you wish to work on the provider, you'll first need the latest version of [Go](http://www.golang.org) installed on your machine (currently 1.15). 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` (note that we typically test older versions of golang as long as they are supported upstream, though we recommend new development to happen on the latest release).
-
-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
-...
-$ $GOPATH/bin/terraform-provider-docker
-...
-```
-
-In order to test the provider, you can simply run `make test`.
-
-```sh
-$ make test
-```
-
-In order to run the full suite of Acceptance tests, run `make testacc`.
-
-*Note:* Acceptance tests create a local registry which will be deleted afterwards.
-
-```sh
-$ make testacc
-```
-
-In order to run only single Acceptance tests, execute the following steps:
-
-```sh
-# setup the testing environment
-$ make testacc_setup
-
-# run single tests
-TF_LOG=INFO TF_ACC=1 go test -v ./docker -run ^TestAccDockerImage_data_private_config_file$ -timeout 360s
-
-# cleanup the local testing resources
-$ make testacc_cleanup
-```
-
-In order to extend the provider and test it with `terraform`, build the provider as mentioned above with
-```sh
-$ make build
-# or a specific version
-$ go build -o terraform-provider-docker_v1.2.0_x4
-```
-
-Remove an explicit version of the provider you develop, because `terraform` will fetch
-the locally built one in `$GOPATH/bin`
+## Example usage
 ```hcl
-provider "docker" {
-  # version = "~> 0.1.2"
-  ...
+# Set the required provider and versions
+terraform {
+  required_providers {
+    # We recommend pinning to the specific version of the Azure Provider you're using
+    # since new versions are released frequently
+    docker = {
+      source  = "kreuzwerker/docker"
+      version = "2.8.0"
+    }
+  }
 }
-```
 
+# Configure the docker provider
+provider "docker" {
+}
 
-Don't forget to run `terraform init` each time you rebuild the provider. Check [here](https://www.youtube.com/watch?v=TMmovxyo5sY&t=30m14s) for a more detailed explanation.
+# Create a docker image resource
+# -> docker pull nginx:latest
+resource "docker_image" "foo" {
+  name         = "c"
+  keep_locally = true
+}
 
-You can check the latest released version of a provider at https://releases.hashicorp.com/terraform-provider-docker/.
-
-Developing on Windows
----------------------
-
-You can build and test on Widows without `make`.  Run `go install` to
-build and `Scripts\runAccTests.bat` to run the test suite.
-
-Continuous integration for Windows is not available at the moment due
-to lack of a CI provider that is free for open source projects *and*
-supports running Linux containers in Docker for Windows.  For example,
-AppVeyor is free for open source projects and provides Docker on its
-Windows builds, but only offers Linux containers on Windows as a paid
-upgrade.
+# Create a docker container resource
+# -> docker run --name foo -d nginx:latest
+resource "docker_container" "foo" {
+  name    = "foo"
+  image   = docker_image.foo.latest
+}
+```
