 This extension contributes the following settings:
 
-- `typos.logLevel`: Logging level of the language server.
+- `typos.diagnosticSeverity`: How typos are rendered in the editor, eg: as errors, warnings, information, or hints.

 - `typos.trace.server`: Traces the communication between VS Code and the language server.
