+### Building
+
+From the main directory, the docker image can be built using the command: 
+
+```bash
+docker build -t perf-test -f Dockerfile-locust .
+```
 
 ### Running
 
-From the main directory, the docker image can be built using the command: `docker build -t perf-test -f Dockerfile-locust .`
-The built image can be run using the command: `docker run -e PODMAN_USERNAME="username" -e PODMAN_PASSWORD="password" -e PODMAN_HOST="localhost:8080" -e QUAY_HOST="http://www.localhost:8080" -e AUTH_TOKEN="abc" --privileged -v /tmp/csivvv:/var/lib/containers -p 8089:8089 --name quay-test -d perf-test`
-Upon successful starting of the container, the locust dashboard is accessible on port 8089.
+#### Locally for dev
+
+```

+    -p 8089:8089 --name quay-test -d perf-test`
+```
+
+Upon successful starting of the container, the locust dashboard is accessible
+on port 8089.
+
+The minimum number of users spawned to run the tests must be at least equal to
+the number of users defined in `testfiles/run.py` to run all user classes.
+
+#### Cluster
+
+The tests are run via locust in distributed mode. There is a single master
+which controls multiple worker pods. The number of replicas for the workers are
+defined in `deploy/locust-distributed.yaml` file. 
+
+Edit the `ConfigMap` `quay-locust-config` in the
+`deploy/locust-distributed.yaml` and set the variables accordingly
+
+Deploy locust on the cluster by running:
 
-The minimum number of users spawned to run the tests must be at least equal to the number of users defined in `testfiles/run.py` to run all user classes.
