+Zecwallet-Lite is z-Addr first, Sapling compatible wallet lightwallet for Zcash. 
+
+**Zecwallet-Lite is currently in beta**
+
+
+## Privacy 
+* While all the keys and transaction detection happens on the client, the server can learn what blocks contain your shielded transactions.
+* The server also learns other metadata about you like your ip address etc...
+* Also remember that t-addresses don't provide any privacy protection.
+
+
+### Note Management
+Zecwallet-Lite does automatic note and utxo management, which means it doesn't allow you to manually select which address to send outgoing transactions from. It follows these principles:
+* Defaults to sending shielded transactions, even if you're sending to a transparent address
+* Sapling funds need at least 5 confirmations before they can be spent
+* Can select funds from multiple shielded addresses in the same transaction
+* Will automatically shield your transparent funds at the first opportunity
+    * When sending an outgoing transaction to a shielded address, Zecwallet-Lite can decide to use the transaction to additionally shield your transparent funds (i.e., send your transparent funds to your own shielded address in the same transaction)
 
 ## Compiling from source
 * ZecWallet is written in C++ 14, and can be compiled with g++/clang++/visual c++.
