-# Building the provider
-
-In this section you will learn how to build and run terraform-provider-sumologic locally. Please follow the steps below:
-
 Requirements
 ------------
 
 - [Terraform](https://www.terraform.io/downloads.html) 0.11.x or 0.12.x
 - [Go](https://golang.org/doc/install) >= 1.9 (to build the provider plugin)
 - [Sumo Logic](https://www.sumologic.com/pricing/)
 
-Build and install
-------------
-`make install`
+# Using the provider
+
+To use the provider run `make install` in the root direcory to install it as a plugin. You can then run `terraform init` to initialize it.
+
+# Developing the provider
+
+If you wish to work on the provider, you'll first need [Go](http://www.golang.org) installed on your machine. 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`.
+
+Clone repository to: `$GOPATH/src/SumoLogic/sumologic-terraform-provider`
+
+```sh
+$ mkdir -p $GOPATH/src/SumoLogic;
+$ cd $GOPATH/src/SumoLogic
+$ git clone [email protected]:SumoLogic/sumologic-terraform-provider.git
+```
+
+Enter the provider directory and build the provider. To compile the provider, run `make build`. This will build the provider and put the provider binary in the `$GOPATH/bin` directory.
+
+```sh
+$ cd $GOPATH/src/SumoLogic/sumologic-terraform-provider
+$ make build
+```
+
+# Testing the provider
+
+In order to test the provider, you can run `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. The environment variables `SUMOLOGIC_ACCESSID`, `SUMOLOGIC_ACCESSKEY`, and `SUMOLOGIC_ENVIRONMENT` must also be set for acceptance tests to work properly.
