 ### Manual Nightly Tests
 
-You can use remote servers to run the [vtr_reg_nightly_test1-7](#vtr_reg_nightly_test1-N) tests. These tests are triggered manually by going to the GitHub Actions menu, selecting the NightlyTestManual workflow and selecting run workflow. Once you do that, the [Nightly Test Manual Workflow](https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/.github/workflows/nightly_test_manual.yml) will be triggered. This run will take approximately 15 hours to complete and will cancel any currently running workflows.
