+### Adding a new network
+
+To support a new network (e.g. Ink, chain ID 57073), run these steps in order:
+
+1. **Generate auxiliary token lists** for the new chain (the chain must already be in `COINGECKO_CHAINS` in `src/scripts/auxLists/utils.ts`):
+
+   ```bash
+   COINGECKO_API_KEY=your_key yarn generateAuxLists
+   ```
+
+   This creates `src/public/CoinGecko.<chainId>.json` and `src/public/Uniswap.<chainId>.json` for the new network.
+
+2. **Fetch permit info** for the new chain. The default token list (`CowSwap.json`) does not include tokens for new networks, so you must pass the path to the chain-specific list as the **second** argument:
+
+   ```bash
+   yarn run fetchPermitInfo -- <chainId> CoinGecko.<chainId>.json
+   ```
+
+   Example for Ink:
+
+   ```bash
+   yarn run fetchPermitInfo -- 57073 CoinGecko.57073.json
+   ```
+
+   Without the second argument, the script would use `CowSwap.json` and skip all tokens (they would have the wrong chainId), leaving the permit file empty.
+
+3. **Include only the new network's files in your PR.** The scripts above may have updated files for other networks too; do not include those changes, as they are updated daily by a cron job.
