-# Playwright-computer-use
+# Playwright Computer Use
 
-This Repo contains a Claude computer use tool that interacts with Playwright.
+Easily use the Claude `computer` tool to let an agent interact with a web browser on your machine (playwright).
 
+This repo contains the required code to connect a Playwright browser to Claude's computer use capabilities. This enables you to use a browser as a tool for your agent, to interact with web pages, and achieve tasks that require a browser.
 
-## Demo
-The Demo consists of the computer use agent by Claude, with access to a Playwright instance.
-To run the demo:
-* Clone the Repo:
+## Quickstart
+
+Clone the Repo
 ```
 git clone https://github.com/invariantlabs-ai/playwright-computer-use.git
 ```
-* setup a virtual environment and install requirements
+
+Install the dependencies:
 ```
-python -m venv venv
-. venv/bin/activate
-pip install .
+cd playwright-computer-use
+pip install -e .
 ```
-* create a `.env` basing on `.env-example`
-* run `python demo.py "How long does it take to travel from Zurich to Milan?"`
 
-## Install
+Create a `.env` basing on `.env-example` ([Anthropic Key](https://console.anthropic.com) and an optional [Invariant Key](https://explorer.invariantlabs.ai) for tracing). Then run:
+
+```
+python demo.py "How long does it take to travel from Zurich to Milan?"
+```
+
+This will spawn an agent on your machine that attempts to achieve whatever task you have in mind in the browser.
+
+## Install As Package
+
 ```
 pip install git://git@github.com/invariantlabs-ai/playwright-computer-use.git
 ```
-## Use
-You can now include `PlaywrightToolbox` as a tool for `Claude`. It would work as any other tool.
+
+## Using the PlaywrightToolbox as a Library
+
+You can also include the `PlaywrightToolbox` as a tool for `Claude`, to enable the use of a playwright browser in an existing agent.
+
 ```python
 tools = tools = PlaywrightToolbox(page=page, use_cursor=True)
