If your workflow source is version controlled `cylc install` records information from the version control system in `~/cylc-run/workflow/log/version`.

For example if you wanted to run an experiment you might do:

```bash
git checkout -b experiment1
# make changes to your workflow
git commit --all --message "experiment1"
cylc install . --run-name experiment1

```

Then the commit hash of the changes you made will be available in `~/cylc-run/workflow/experiment1/log/version/vcs.json`.

Alternatively, you could choose not to commit your changes, and you would be able to view them at `~/cylc-run/workflow/experiment1/log/version/uncommitted.diff`.
