 ### Arguments with forbidden keys
 
-To ensure users don't use reserved words in key-value pairs, you may want to enforce rules to avoid misusages.
+To ensure users don't use reserved words in key-value pairs, you may want to enforce rules to avoid misuse.
 The `forbidden-key` option causes `sloglint` to report usages of forbidden keys. These keys could be typically controlled by slog handlers and its usage should be preserved to avoid key duplication.
 
 ```go
-slog.Info("a user has logged in", "reserved_key", 49) // sloglint: keys include forbidden values
+slog.Info("a user has logged in", "forbidden_key", 49) // sloglint: "forbidden_key" key is forbidden and should not be used
 ```
