+### Redis connections
+
+Pluk accepts `redis://` and `rediss://` URLs, including password-only or ACL
+username/password authentication and a logical database index such as `/2`.
+TLS connections use full certificate and hostname verification. Saved passwords
+are separated from connection metadata and stored in the macOS Keychain.
+
+The key browser uses cursor-based `SCAN` pages and never uses `KEYS`. Strings,
+hashes, lists, sets, sorted sets, streams, and RedisJSON values can be inspected;
+streams are read-only and show a bounded first page in this version, while large
+string and RedisJSON values currently load in full. RedisJSON appears only when
+the module is installed. Pluk currently requires Redis 6 or later (or a
+compatible Valkey server) because the client negotiates RESP3. The underlying
+client guarantees Redis compatibility through 7.2.4; newer Redis releases may
+work but should be validated for production use. Cluster, Sentinel, and Redis
+over SSH tunnels are not supported yet.
+
 ## Building from source
 
 You need macOS 15 or later and Xcode 26 or later with Swift 6 support.
