Hi @dzienisz ,

Contributing as part of hacktoberfest 2022 (https://hacktoberfest.com/). If it's not too much of a bother, will it be okay to tag the PR with hacktoberfest-accepted label, just to it can be officially tagged as participating?

Thank you so much.

[dzienisz]

Yes, thanks!

Hi @romanbalayan, I'd rather keep the example code shorter, only mentioning require('sonarqube-scanner').customScanner; since it is the only meaningful part.

Have you tried what you are suggesting, or are you basing this on inference?

[romanbalayan]

Hi @gabssnake,

Sure, will take out the code block, and just maintain the specific change required when using the customScanner.

And yes, tried this out prior to creating the pull request.

Hi @gabssnake,

Anything I should be looking out for this?

Also @dzienisz, sorry to bother again, is it okay for the PR to be tagged with the hacktoberfest-accepted label?

Thanks!
