-You can also set `DOTNET_INSTALL_DIR` to a value based on runtime variables, such as `$HOME/.dotnet` or `${{ runner.temp }}/.dotnet` before the `setup-dotnet` step:
-
-```yml
-    - name: Set DOTNET_INSTALL_DIR
-      run: echo "DOTNET_INSTALL_DIR=$HOME/.dotnet" >> $GITHUB_ENV
-```
-> **Note**: On some self-hosted or large Linux runners, installing .NET under the default `/usr/share/dotnet` location may fail due to insufficient permissions. To ensure successful installation, set `DOTNET_INSTALL_DIR` to a user-writable path.
-
-## Recommended permissions
-
-When using the `setup-dotnet` action in your GitHub Actions workflow, it is recommended to set the following permissions to ensure proper functionality:
-
-```yaml
-permissions:
-  contents: read # access to check out code and install dependencies
-```
