+### AgentLab Server and AgentLab Controller
+
+The AgentLab Server and Controller are two components that work together to control and debug an agent deployed in an environment.
+
+#### Prerequisites
+
+First, set a `.env` file at the root of the repo with the following content:
+
+```bash
+# LLM Creds (Azure as an example)
+AZURE_OPENAI_ENDPOINT=<YOUR_AZURE_OPENAI_ENDPOINT>
+AZURE_OPENAI_API_KEY=<YOUR_AZURE_OPENAI_API_KEY>
+AZURE_OPENAI_API_VERSION=<YOUR_AZURE_OPENAI_API_KEY>
+
+# ServiceNow dev instance creds
+SNOW_INSTANCE_URL=https://<your_servicenow_dev_instance>.service-now.com/
+SNOW_INSTANCE_UNAME="admin"
+SNOW_INSTANCE_PWD=<password>
+
+# MiniWob
+MINIWOB_URL="file:///path/to/BrowserGym/miniwob-plusplus/miniwob/html/miniwob/" 
+```
+
+#### Launch the server
+
+The AgentLab Server is responsible for hosting and enabling interaction with the environment. It is a lightweight FastAPI server that handles the BrowserGym environment and provides a REST API for the controller.
+
+To launch the server, open a terminal and run (you will need to keep this terminal open for the next step):
+
+```bash
+agentlab-server
+```
+
+#### Launch the controller
+
+The AgentLab Controller is a streamlit app responsible for controlling the agent and how it interacts with the environment hosted on the server.
+
+To launch the controller, open a new terminal and run:
+
+```bash
+agentlab-controller
+```
