+# R2 SQL Configuration
+
+Auth and setup. For the current permission matrix and wrangler flags, pull `https://developers.cloudflare.com/r2-sql/reference/wrangler-commands/` and the R2 Data Catalog manage-catalogs doc.
+
+## Prerequisites
+
+- R2 bucket with Data Catalog enabled ([r2-data-catalog/configuration.md](../r2-data-catalog/configuration.md))
+- R2 API token: **R2 Storage Admin Read & Write** (includes R2 SQL Read), or add **R2 SQL Read** explicitly
+- Wrangler CLI (for CLI queries)
+
+> Open-beta limitation: R2 Storage **Admin Read & Write is required even for read-only R2 SQL queries**.
+
+## Enable Catalog + Get Warehouse
+
+```bash
+npx wrangler r2 bucket catalog enable my-bucket
+```
+
+You query by **warehouse** name (`{ACCOUNT_ID}_{BUCKET}`), shown in the output alongside the Catalog URI.
+
+## Configure Auth
+
+### Wrangler CLI
+
+```bash
+export WRANGLER_R2_SQL_AUTH_TOKEN=<your-token>
+# or a .env file in the project dir (auto-loaded): WRANGLER_R2_SQL_AUTH_TOKEN=<your-token>
+```
+
+> Wrangler does **not** use the `wrangler login` OAuth session for R2 SQL — the env var is required.
+
+### REST API
+
+```bash
+curl -X POST \
+  "https://api.sql.cloudflarestorage.com/api/v1/accounts/$ACCOUNT_ID/r2-sql/query/$BUCKET" \
+  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
+  -d '{"query": "SELECT * FROM default.my_table LIMIT 10"}'
+```
+
+## Verify Setup
+
+```bash
+npx wrangler r2 sql query "${ACCOUNT_ID}_my-bucket" "SHOW DATABASES"
+npx wrangler r2 sql query "${ACCOUNT_ID}_my-bucket" "SHOW TABLES IN default"
+```
