 ### The Basics
 
-TODO(anonimal): finish
+@garlic-encryption is @I2P's implementation of @message based @layered-encryption (similar to flow-based [Onion-Routing](https://en.wikipedia.org/wiki/Onion_routing)).
+
+By @encrypting @messages in layers, this allows a @message to be routed through a sequence of proxies without allowing the proxies (or any intermediaries) to read the contents of the @message. @Layered-Encryption is a fundamental feature in @Kovri, @I2P, and [Tor](https://torproject.org) and is the cornerstone for securing anonymity within these overlay-networks.
 
 ### In-depth information
 
-TODO(anonimal): finish
+For @garlic-encryption, the primary difference between @Kovri/@I2P and Tor is:
+
+- @Kovri/@I2P bundles multiple @messages together to form garlic "cloves"
+  - any number of messages can be contained in a "clove" instead of *only* a single message
+- @Kovri/@I2P uses [ElGamal](https://en.wikipedia.org/wiki/ElGamal)/[AES](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard) @encryption for @messages and @transports
