+### About LBRY SDK (lbrynet)
+
+**Q: Does this download the LBRY blockchain?**
+
+**A:** No! The LBRY SDK is a light client that:
+- Connects to LBRY's servers and peer network
+- Downloads only the content you request
+- Does **NOT** require blockchain synchronization (unlike Bitcoin)
+- Uses minimal disk space (just the downloaded content)
+
+The LBRY SDK acts like a specialized download manager for the LBRY network, not a full blockchain node.
