 ## Packages
-* `bncs` - the main Battle.net Chat Service (BNCS)
-  * `crev` - functions and classes for handling CheckRevision
-    * `check_version(archive, formula, [files[]], [platform], [timestamp])` - performs CheckRevision() and returns results
-    * `get_file_meta(file)` - returns version number and info string of a PE file
-    * NOTE: Lockdown CheckRevision is not currently supported and will raise an exception if attempted.
-  * `utils` - general utilities for the library and BNET ecosystem
-    * `DataBuffer`, `DataReader` - binary packet buffer for writing and reading respectively
-  * `hashing` - handles XSha1, NLS, and SigVerify (CD key and password hashing)
-    * `KeyDecoder` - decodes CD keys and returns hashing values
-    * `NLSClient`, `NLSServer` - client and server implementations of the 'new login system' (NLS)
-    * `check_signature(sig, ip)` - server signature verification
-    * `xsha()`, `hash_password`, `double_hash_password` - Broken SHA-1 (xsha) hashing
+* `bncs` - handles connecting to and interacting with the Battle.net Chat Service
+  * `chat` - relating to the chat environment (users, channels, flags)
+  * `crev` - functions and classes for handling the client version checking process - supports classic, lockdown, and simple/modern variants
+    * `get_file_meta(file)` - returns the version number (DWORD) and filename, timestamp, and size of the given file, usually an EXE
+    * `LocalHashingProvider(root)` - class which performs version checking operations from the local file system, partially interface compatible with `bnls.BnlsClient()`
+  * `hashing` - handles CD key and password hashing
+    * `KeyDecoder.get(key)` - decodes a given CD/product key and identifies it
+    * `NLSClient(username, password)`, `NLSServer` - client and server implementations of the 'new login system' (NLS), an SRP-based system for verifying account logins
+    * `check_signature(sig, ip)` - verifies that the signature presented by a server is valid for that server's IP address
+    * `hash_password(password)`, `double_hash_password(password, c_token, s_token)`, `xsha1(data)` - hashes passwords and other data with Blizzard's custom SHA1 implementation
+    * `lockdown_sha1(data)` - hashes data using another one of Blizzard's custom SHA1 implementations
+  * `mcp` - handles the Diablo 2 realm service
+  * `products` - contains packet ID constants and classes for reading and writing BNCS packets
+  * `utils` - generic utilities (packet buffer, async TCP client)
+  * `BnetClient()` - handles a complete connection to the chat service
+  * `BnetProduct.get(pid)` - provides access to metadata on game clients that can connect to Battle.net
+  * `BnetIconFile.load(file)` - extracts game icons from an icon file (.bni)
+  * `CreditQueue()` - a system for delaying outbound chat messages to avoid rate limiting/flooding
 * `bnls` - the Battle.net Logon Service (3rd party)
-  * `BnlsClient` - a client for interacting with a BNLS server
+  * `BnlsClient()` - a client for interacting with a BNLS server
 * `bnftp` - the Battle.net FTP service
   * `BnftpClient` - downloads files available through the BNFTP protocol
 * `botnet` - the Valhalla Legends BotNet service (used for inter-bot communication)
   * `BotNetClient` - a client for interacting with a BotNet server
-  
-Packages also contain constants used with each system. (SID_AUTH_INFO, BNLS_AUTHORIZE, EID_SHOWUSER, etc).
