 ## Some code FAQ
 
@@ -61,7 +17,7 @@ public:
 Every variable from the config needs to be found in a hashmap. To limit the amount of hashmap searches, getting a config option looks like this:
 
 ```cpp
-static auto *const PFOLLOWMOUSE = &g_pConfigManager->getConfigValuePtr("input:follow_mouse")->intValue;
+static auto* const PFOLLOWMOUSE = &g_pConfigManager->getConfigValuePtr("input:follow_mouse")->intValue;
 ```
 
 Since the hashmap _cannot_ be mutated during runtime, this pointer will always be valid, and will not require hashmap lookups every single time it's read.
