 ## Recommended setup for public repositories
 
 Workflows triggered by pull requests from forked repositories are executed with read-only token and therefore can't create check runs.
-To workaround this security restriction it's required to use two separate workflows:
-1. `CI` runs in the context of PR head branch with read-only token. It executes the tests and uploads test results as build artifact
-2. `Test Report` runs in the context of repository main branch with read/write token. It will download test results and create reports
