 ### How does this change benefit high ping players?
 **Knockback control.** For example, it will be easier to escape crit chains and punish crit.
 
-<<<<<<< Updated upstream
-### How do I change the ping offset?
-Open up `config.yml` and edit the line that says `ping_offset: 25`. Replace 25 with your desired ping offset.
-;
-Then just type
-```
-/knockbacksync reload
-```
-or restart your server.
-=======
 ### Why was the configurability of ping offset removed?
 **It promotes consistency across all servers.** Extensive testing with top players has shown that an offset of 25 provides a balanced experience for everyone.
 
 ### How do I change the ping offset?
 **You must run a modified build of KnockbackSync.** The variable can be changed inside of the [PlayerData](common/src/main/java/me/caseload/knockbacksync/player/PlayerData.java) class.
