+## Configuration Tips
+
+### Redis URL Format
+
+Build Redis URLs from environment variables:
+
+```typescript
+// Basic connection
+const redisUrl = `redis://localhost:6379`
+
+// With password
+const redisUrl = `redis://:password@localhost:6379`
+
+// With username and password
+const redisUrl = `redis://user:password@localhost:6379`
+
+// From environment variables
+const redisUrl = `redis://${process.env.REDIS_HOST}:${process.env.REDIS_PORT}`
+```
+
+### Adapter Options
+
+Redis adapters accept two parameters:
+
+```typescript
+new RedisStateAdapter(
+  { url: redisUrl },              // Connection config
+  { keyPrefix: 'app:', ttl: 3600 } // Adapter options
+)
+```
+
+**Common options:**
+- `keyPrefix` - Prefix for all keys (helps organize data)
+- `ttl` - Time-to-live in seconds (auto-expire old data)
+- `lockTTL` - Lock timeout for cron jobs
