 # SRE Incident Response - OpenEnv Environment
 
-This Hugging Face Space runs the SRE Incident Response OpenEnv environment.
+This repository provides an **OpenEnv-compatible** environment where an agent acts as an on-call **Site Reliability Engineer (SRE)**. The environment exposes a simple HTTP API (FastAPI) that supports episodic rollouts via `/reset` and `/step`, plus grading via `/grader`.
+
+## What’s in this repo
+
+- **Environment server**: `app/main.py` (FastAPI, OpenEnv-style endpoints)
+- **Task logic**: `app/tasks/` (three incident scenarios)
+- **Inference runner**: `inference.py`
+  - Uses an OpenAI model if `OPENAI_API_KEY` is set
+  - Otherwise falls back to a deterministic, no-network policy
+
+## Run locally (Docker)
+
+Build and run:
+
+```bash
+docker build -t sre-incident-env .
+docker run --rm -p 7860:7860 sre-incident-env
+```
+
+Then check:
+
+```bash
+curl http://localhost:7860/health
+curl http://localhost:7860/tasks
+```
+
+## Run locally (Python)
+
+Install:
+
+```bash
+pip install -r requirements.txt
+```
+
+Start the server:
+
+```bash
+python -m uvicorn app.main:app --host 0.0.0.0 --port 7860 --workers 1
+```
+
+## Inference / evaluation
+
+Run inference against a running environment:
+
+```bash
+python inference.py --base-url http://localhost:7860
+```
+
+Notes:
+
+- **Exit codes**: by default `inference.py` exits **0** if it completes (even if tasks fail), to avoid “runner failed” false negatives. Use `--strict-exit` if you want non-zero on failed tasks.
+- **Auto-start**: if `--base-url` is `http://localhost:7860` and the server isn’t running, `inference.py` will try to start the local server automatically.
+
+## Hugging Face Spaces
+
+This repo is set up for **Docker Spaces** (see `Dockerfile`). The server binds to port **7860**, and `/health` is used as a health check.
+
+## Meta x PyTorch Hackathon submission notes
+
+If the hackathon evaluator runs `inference.py` directly, this repo is designed to:
+
+- Install cleanly from `requirements.txt`
+- Bring up the environment server (Docker or local)
+- Run `inference.py` without crashing or returning a non-zero code just because a baseline policy didn’t “pass”
