-# pythnet-watcher
+# Pythnet Watcher
+
+This project is a Rust-based utility for listening to messages on **Pythnet**, processing them, and signing them as a **Wormhole guardian**.
+
+---
+
+## 🚀 Getting Started
+
+### 🛠️ Build the Project
+
+```bash
+cargo build --release
+```
+
+Or for development:
+
+```bash
+cargo build
+```
+
+---
+
+### ▶️ Run the Project
+
+You can run the project using `cargo run` by passing the required flags:
+
+```bash
+cargo run -- \
+  --pythnet-url wss://api2.pythnet.pyth.network \
+  --secret-key /path/to/secret.key \
+  --wormhole-pid H3fxXJ86ADW2PNuDDmZJg6mzTtPxkYCpNuQUTgmJ7AjU \
+  --accumulator-address G9LV2mp9ua1znRAfYwZz5cPiJMAbo1T6mbjdQsDZuMJg
+```
+
+---
+
+### 🌱 Environment Variables (Optional)
+
+Instead of CLI flags, you can also set environment variables:
+
+```bash
+export PYTHNET_URL=wss://api2.pythnet.pyth.network
+export SECRET_KEY=/path/to/secret.key
+export WORMHOLE_PID=H3fxXJ86ADW2PNuDDmZJg6mzTtPxkYCpNuQUTgmJ7AjU
+export ACCUMULATOR_ADDRESS=G9LV2mp9ua1znRAfYwZz5cPiJMAbo1T6mbjdQsDZuMJg
+
+cargo run
+```
+
+---
+
+### 🧪 Testing Locally
+
+To test in a non-production environment (e.g. with devnet or a local Pythnet fork), just provide a different `--pythnet-url` and optionally use custom `--wormhole-pid` and `--accumulator-address`.
