 * Effective, lightweight, and easy-to-use
 * No unnecessary features and clean code
 * Protection against all kinds of bot attacks

 ## Checks
 
-- New player logins are queued to prevent spam login attacks.
-- [Fallback](https://github.com/jonesdevelopment/sonar#fallback) is Sonar's main component designed to prevent
-  all types of bots.
-- Spigot & BungeeCord
-  - Duplicate login/status packet spam fix
-  - Run server ping handling asynchronously
+- [Fallback](https://github.com/jonesdevelopment/sonar#fallback) is Sonar's main anti-bot component
+- Sonar queues new player logins to prevent spam login attacks
+- Sonar checks the handshake packets for legitimacy
+- Protective components only on BungeeCord:
+  - Sonar validates the login/server ping packets
+  - Sonar handles all server pings asynchronously
   - The Varint decoder is updated to Velocity's
     improved [MinecraftVarintFrameDecoder](https://github.com/PaperMC/Velocity/blob/dev/3.0.0/proxy/src/main/java/com/velocitypowered/proxy/protocol/netty/MinecraftVarintFrameDecoder.java).
 
 ### Fallback
 
-Fallback analyzes a player's behavior before joining the actual server, therefore stopping malicious traffic from ever
-reaching the backend.
-It is supposed to be an instant, powerful, and invisible method of verification that should prevent all typical and
-advanced types of bots.

+Fallback also protects against huge spambot attacks since it queues the incoming connections, therefore making it technically impossible to have a ton of bots join the server at the same time.
 
 ### False positives
 
-Fallback is unlikely to ever falsely prevent a player from joining the server since Minecraft uses the TCP protocol which means that packets are always sent in the correct order. Therefore, lag or ping should not affect the bot check.
-However, there are some edge cases where Fallback might not receive packets within the necessary time period. In this case, Sonar tries to account for these edge cases in order to prevent false positives. For example, some higher Minecraft versions have a bug where the client sometimes sends a packet out of order. Sonar accounts for that and does not falsely blacklist clients.
-If you or one of your players experiences a false positive, make sure to report it by opening
-a [GitHub issue](https://github.com/jonesdevelopment/sonar/issues) or a ticket
-on [Discord](https://jonesdev.xyz/discord/).
