+# Setup
+
+Get the bot ready before running it.
+
+## What it does
+Creates a safe baseline so your accounts and config are ready.
+
+## How to use
+1. Install Node.js 20 or newer.
+2. Copy `src/accounts.example.jsonc` to `src/accounts.jsonc` and fill in your accounts.
+3. Review `src/config.jsonc`; defaults work for most people.
+4. (Optional) set `DISCORD_WEBHOOK_URL` in your environment for alerts.
+
+## Example
+```jsonc
+[
+  {
+    "email": "you@example.com",
+    "password": "your-password"
+  }
+]
+```
