 # UID2 Operator Performance Testing Tool
 The following instructions will work for any operator.
 
-## Steps

 ### Step 1 - Configure the K6 script
 The script as checked in has a basic config that will run a check against all endpoints.

+## Python Locust Scripts
+### Step 1 - Configure Virtual Environment
+In order to run the python script, best practise is to create a virtual environment:
+```
+python3 -m venv venv
+source venv/bin/activate
+```
+
+### Step 2 - Modify `uid2-client-python` to include eclapsed time
+See [this](https://github.com/IABTechLab/uid2-client-python/pull/55) as an example.
+
+Once modified the `uid2-client-python` repo, run `python3 -m pip install -e /Users/katherine.chen/ttdsrc/uid2-client-python`
+
+### Step 3 - Install Required Packages
+Once you've sourced into the venv, install required packages:
+```
+python3 -m pip install locust
+python3 -m pip install -e <path to uid2-client-python>
+```
+
+### Step 4 - Run Load Test
+Run below command to start the load test:
+```
+venv/bin/python -m locust -f performance-testing/uid2-operator/locust-identity-map.py <base_url> <client_key> <client_secret>
+```
