+# Connect - A safer OnClientPreConnect forward
+
+This extension provides a OnClientPreConnect forward (similar to CBaseServer's), but does proper checking to prevent malicious people spoofing SteamIDs.
+
+If you are currently using CBaseServer for reserved slots, it's possible for a client to spoof an admin's SteamID and cause someone to be kicked from the server (although they would be later denied, so they couldn't actually join the game).
+This extension does these checks before OnClientPreConnect is fired, so this isn't possible.
+
+There are some additional features such as being able to change the password provided before it's checked (see included example plugin) and the ability to reject the client with a reason (like SourceMod's later OnClientConnect forward).
+
+Only the Source 2009 engine is supported, as it's the only one that's been updated to use the new authentication system.
+
+# Provided forwards
+
+```
+public bool OnClientPreConnectEx
+(
+  const char[] name,
+  char password[255],
+  const char[] ip,
+  const char[] steamID,
+  char rejectReason[255]
+)
+{
+    // ...
+}
+```
+
+`return false;` to disallow the client from joining, and change `rejectReason` to what you want them to be shown when denied.
+
+Note that this function is called before the client has a client index on the server.
