-Prerequisites:
-- AWS SAM CLI
-- Docker daemon running
-
-Environment:
-- `LAMBDA_AWS_ROLE_ARN`
-- `LAMBDA_STACK_NAME`
-- `DRIVERS_ATLAS_GROUP_ID`
-- `MONGODB_URI`
-- `AWS_ACCESS_KEY_ID`
-- `AWS_SECRET_ACCESS_KEY`
-- `AWS_REGION`
-
-Function Setup:
-
-1. `sam init` and follow instructions for your language, creating a hello world example.
-
-2. Modify the generated function and template.yaml, renaming as needed, and add the
-   following functionality:
-   - Must create and cache a `MongoClient` during the init phase of the function.
-     - For dynamic languages this is at module load time.
-     - For static languages this can be done in the function constructor.
-     - The MongoClient must get the uri from the `MONGODB_URI` environment variable.
-   - The following events must be listened to on the client, and should be added and removed
-     within the handler function itself.
-     - command started
-     - command succeeded
-     - command failed
-     - server heartbeat started
-     - server heartbeat succeeded
-     - server heartbeat failed
-     - connection created
-     - connection closed
-  - The function itself must insert one document and delete that document
-  - The function must return JSON with the average duration times of each suceeded
-    event, the number of connections created and closed, and heartbeat count:
-    ```json
-      {
-        "averageCommandSuceeded": 40,
-        "averageHeartbeatSuceeded": 20,
-        "openConnections": 1,
-        "heartbeatCount": 10
-      }
-    ```
-  - Update template.yaml to provide a default MONGODB_URI in the Globals section:
-    ```yaml
-      Globals:
-        Function:
-          Timeout: 10
-          Environment:
-            Variables:
-              MONGODB_URI: 'mongodb://127.0.0.1:27017'
-    ```
-
-3. Create env.json with the format:
-    ```json
-      {
-        "Parameters": {
-          "MONGODB_URI": "<uri to test>"
-        }
-      }
-    ```
-
-4. `sam build` from the project directory to build the function.
+AWS Lambda Testing
+------------------
 
-5. `sam local invoke --env-vars ./env.json` to create the container and run the function locally.
+Running locally
+===============
 
-Function Testing:
-
-1. Create an Atlas M10 sharded cluster.
-
-2. Get URI to connect to cluster.
-
-3. Set MONGODB_URI in the function environment.
-
-4. `sam build`
-
-5. Assume role DRIVERS-2384
-
-6. `sam deploy ==stack-name ${LAMBDA_STACK_NAME}` --capabilities CAPABILITY_IAM --resolve-s3`
+Prerequisites:
 
-7. Get the function arn
+- AWS SAM CLI
+- Docker daemon running
 
-7. `aws lambda invoke --function-name <function arn> standard.json`
+Steps
+=====
 
-8. Sleep 30 seconds.
+- `sam build` from the `test/lambda`.
 
-7. `aws lambda invoke --function-name <function arn> standard.json`
+- `sam local invoke --parameter-overrides "MongoDbUri=mongodb://127.0.0.1:27017"`
