 All workflows in this repository use the following logic for selecting the runner:
 
 ```yaml
-runs-on: ${{ vars.REPO_RUNNER_LABELS && fromJSON(vars.REPO_RUNNER_LABELS) || 'ubuntu-latest' }}
+runs-on: ${{ vars.runner_labels_ghub_standard_x64 && fromJSON(vars.runner_labels_ghub_standard_x64) || vars.REPO_RUNNER_LABELS && fromJSON(vars.REPO_RUNNER_LABELS) || 'ubuntu-latest' }}
 ```
 
 This means:
 
-- If your repository defines a variable named `REPO_RUNNER_LABELS` (e.g., in repository or organization settings), its value will be used as the runner label(s).  
+- If your repository defines a variable named `runner_labels_ghub_standard_x64` or `REPO_RUNNER_LABELS` (e.g., in repository or organization settings), its value will be used as the runner label(s).  
   This allows you to use **self-hosted runners** or any custom runner configuration.
-- If `REPO_RUNNER_LABELS` is **not set**, the workflow will default to GitHub-hosted `ubuntu-latest`.
+- If `runner_labels_ghub_standard_x64` or `REPO_RUNNER_LABELS` is **not set**, the workflow will default to GitHub-hosted `ubuntu-latest`.
 
 **Why?**  
 This approach allows forked repositories or projects with special requirements to use their own runners, while everyone else gets a reliable default.
 
-> ℹ️ **Tip:** To use a self-hosted runner, set the `REPO_RUNNER_LABELS` variable in your repository or organization settings to the label(s) of your runner.

+
+### Runner labels variable naming convention
+
+Since it is very likely the case that different workflows will need different runners of different sizes, oses and architectures to be cost efficiently using the runner infrastructure the variable that specifies the runner labels shall follow this naming convention:
+
+`runner_labels_<os>_<size>_<architecture>`
+
+As of today following runner label variables are supported:
+
+- runner_labels_ghub_standard_x64
+  - os: ghub - GitHub Ubuntu latest OS image
+  - size: standard - Maps to the specs of the "Ubuntu latest" GitHub hosted runner
+  - architecture: x64 - Maps to the architecture of the standard "Ubuntu latest" GitHub hosted runner. The value is taken from the [GitHub hosted runners reference page](https://docs.github.com/en/actions/reference/runners/github-hosted-runners)
+
+Due to this new naming convention the variable **REPO_RUNNER_LABELS is deprecated** and will be removed eventually!
