Install packages

Packages (managed or not) must never be directly installed in a major org (integration, uat, preprod, production), it has to be done in dev sandbox / scratch orgs

If you installed a package on a dev sandbox or scratch org, use DevOps Pipeline -> Installed Packages Manager to retrieve the package configuration before creating your merge request (be careful of what you commit in .sfdx-hardis.yml file !)

Select Deployments if you want the package to be automatically installed on major orgs
Select Scratch if you want the package to be automatically installed on new Scratch Orgs

Once packages are referenced in .sfdx-hardis.yml, they will automatically be installed on major orgs during CI/CD deployments

If you want packages to be installed during deployment check, see with your release manager to define installPackagesDuringCheckDeploy: true in your .sfdx-hardis.yml config file.
