Thanks for the contribution! Besides the minor comments, please ensure that markdown is valid and also run ./scripts/licenses-list.sh --update

[ilyaaay]

@spetz I added some changes.

[spetz]

@ilyaaay only these 2 things left and then we can merge :) on the other hand, the iggyrs/iggy-web-ui will be updated once we have the apache docker hub for web ui.

[ilyaaay]

@spetz I finished all problems :)

[spetz]

@ilyaaay thanks, let's run the workflows and merge it :)

[spetz]

@ilyaaay one more thing, we need all the files to have the appropriate Apache license headers, so please delete the LICENSE and NOTICE files from helm directory, and apply the common license header to all the source files (except README of course). Also, the mardkown linter seems to be failing.

[spetz]

Apply the Apache license to all the source files.

[ilyaaay]

@spetz I also update deps file again and applied your instructions (remove license, disclaimer, notice pull_request_template) files.

[spetz]

@ilyaaay the Apache license headers are still missing and the markdown isn't formatted correctly - please check the CI validation errors. You can either run just licenses-fix or add the license headers manually.

[spetz]

@ilyaaay unfortunately, markdown is still invalid, could you please fix this, as it seems to be the last issue?

[ilyaaay]

@spetz yeah, okey

@ilyaaay based on the failed CI https://github.com/apache/iggy/actions/runs/16201196091/job/45740724629?pr=1911

Looks good, thank you!
