 # Contract Pinger
+
 Simple server that can request a signature from any supported network. Used in load and synthetic tests.
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js (v18+ recommended)
+- pnpm
+
+### Install dependencies
+
+```sh
+pnpm install
+```
+
+### Development
+
+Run the server in development mode (auto-reloads on changes):
+
+```sh
+pnpm dev
+```
+
+### Build
+
+Transpile TypeScript to JavaScript:
+
+```sh
+pnpm build
+```
+
+### Run (Production)
+
+```sh
+pnpm start
+```
+
+### Run (Development)
+
+```sh
+pnpm dev
+```
+
+### Test
+
+Run all integration and unit tests:
+
+```sh
+pnpm test
+```
+
+### Code Formatting
+
+To format all code in the project using Prettier and your `.prettierrc` settings, run:
+
+```sh
+pnpm format
+```
+
+This will automatically format your codebase according to the project's style rules.
+
+## Environment Variables
+
+Copy `.env.example` to `.env` and fill in the required values for your environment.
