### Description

Update readme for integration tests

 - Create a machine using the variables provided below in `us-west-1`
 - Run a test using `observeinc/collection/aws//modules/testing/exec` module to accept python scripts located at `integration/tests/scripts` 
 
+### Pre-requisites
 
-### Variables 
+Ensure you have  the following:
+- Built version of the agent ( in `observe-repos/observe-agent/dist`) using `go-releaser` 
+- Blunderdome Admin Access in AWS (used to assume the `gh-observe_agent-repo` role for testing )
+- Observe Collection URL & Datastream Token to test with 
+- Generated Private & public key pair ( name to `test_key.pub` & `test_key.pem`) 
+- Terraform provider overide and terraform variables (see below section on how to do this)
+
+
+**Building the agent**:
+
+```
+observe-agent git:(nikhil/update-RM) ✗ goreleaser release --snapshot --clean --verbose
+```
+
+If agent distributable is not built, you may get the following message:
+
+```
+│ Error: Test assertion failed
+│ 
+│   on tests/integration.tftest.hcl line 65, in run "test_install":
+│   65:     condition     = output.error == ""
+│     ├────────────────
+│     │ output.error is "FileNotFoundError: [Errno 2] No such file or directory: '/Users/nikhil.dua/Documents/observe-repos/observe-agent/dist'"
+│ 
+│ Error in Installation Test
+```
+
+
+**SSH Key Pairs**: 
+
+Generate in PEM format for the OpenSSH Key that will be used by Terraform EC2 Modules:
+
+```
+ssh-keygen -m PEM
+```
+
+For more info on generating SSH keys, see [here](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/create-key-pairs.html#how-to-generate-your-own-key-and-import-it-to-aws)
+
+Ensure you have  `./test_key.pub`  and `./test_key.pem` in the `integration` directory. This can also be changed and specifed in the `integration/tests.auto.tfvars` file. 
+
+Ensure the extensions are correct! 
+
+
+**AWS UI Access (optional)**:
+
+For AWS UI access for viewing machines: 
+1. Login to Britive Blunderdome 
+
+2. Navigate to AWS Console 
+
+<p align="left">

+
+3. Click Switch role and input details for `nikhil-ps-account` which is the member account for integration testing within Blunderdome. Details are the following:

+
+4. You can now access EC2 machines and download key pairs (same as what Github Actions workflow uses)
+
+5. Ensure you're in `us-west-1`

 The tests are run using the following variables. These can be set in the `integration/tests.auto.tfvars` file for local testing.

+### Local Testing (without terraform test)
 
 Any of the python scripts in the `/scripts` directory can be tested by running them directly, granted an EC2 Machine exists. As the scripts rely on the outputs of `create_ec2` and `setup_observe_variables` modules to be passed in as environment variables, these environment variables can be manually set if the set up modules are not ran.
