 # Kernel Python Sample App - OpenAI Computer Use
 
-This is a Kernel application that demonstrates using the Computer Use Agent (CUA) from OpenAI.
+This is a Kernel application that demonstrates using the Computer Use Agent (CUA) from OpenAI with Kernel's native browser control API.
 
-It generally follows the [OpenAI CUA Sample App Reference](https://github.com/openai/openai-cua-sample-app) and uses Playwright via Kernel for browser automation.
+It uses Kernel's computer control endpoints (screenshot, click, type, scroll, batch, etc.) and includes a `batch_computer_actions` tool that executes multiple actions in a single API call for lower latency.
 
-See the [docs](https://www.kernel.sh/docs/quickstart) for more information.
+## Local testing
+
+You can test against a remote Kernel browser without deploying:
+
+```bash
+cp .env.example .env
+# Fill in OPENAI_API_KEY and KERNEL_API_KEY in .env
+uv run run_local.py
+# JSONL event output
+uv run run_local.py --output jsonl
+```
+
+The local runner defaults to human-readable logs (`text`). Use `--output jsonl` for one structured event per line (including backend events). Add `--debug` to include verbose in-flight events.
+
+## Deploy to Kernel
+
+```bash
+kernel deploy main.py --env-file .env
+kernel invoke python-openai-cua cua-task -p '{"task":"go to https://news.ycombinator.com and list top 5 articles"}'
+# JSONL logs for invocation
+kernel invoke python-openai-cua cua-task -p '{"task":"go to https://news.ycombinator.com and list top 5 articles","output":"jsonl"}'
+```
