 ## Known Limitations
 
  - Only Linux on x86_64 is tested for now
- - TLS is not yet supported, but is targeted for a future enhancement
  - Validation of configuration is non-existent -- incorrect config will not work with little indication as to why
- - Proper logging of the input execution is not yet implemented
+ - Proper logging of the input execution is not yet implemented. You may or may get a log entry of any issues.
