@nlamirault Could you please update the charts by running make check-charts at the root of the project?

[nlamirault]

make check-charts where do you find this command ? @jaellio

[jaellio]

Hi @nlamirault, at the root of the OSM project there is a makefile that defines the check-charts tag. The check-charts task will regenerate charts/osm/README.md. In your branch, if you navigate to the root of the repository and run make check-charts the task will run and you can push a new commit. Let me know if you have any questions!
