Nice work @holger.

So you’ve decided to coalesce all the experiments into a single repo, with a branch for each?

@micael and @aekiss have done the same thing for their ACCESS-OM3 configurations

> **[GitHub - COSIMA/MOM6-CICE6: ACCESS-OM3 MOM6-CICE6 configurations](https://github.com/COSIMA/MOM6-CICE6)**

> ACCESS-OM3 MOM6-CICE6 configurations . Contribute to COSIMA/MOM6-CICE6 development by creating an account on GitHub.

Though I believe they are planning on stripping all model configuration from the `main` branch and just have the `README` explaining how to checkout an experiment branch and run the model.

There was some discussion about this in the most recent TWG meeting

I would suggest your instructions should recommend cloning the repo to a unique experiment name that reflects what they wish to run, e.g.

```auto
git clone -b pre-industrial https://github.com/coecms/access-esm pre-industrial-albedo-mod
cd pre-industrial-albedo-mod

```

You might want to set the `experiment` name in the `config.yaml` to the unique name of the experiment (the branch name in this case). This would avoid namespace collisions that would occur if someone switched to another experiment branch and ran from the same directory.

From [the docs](https://payu.readthedocs.io/en/latest/config.html#model)

> `experiment` (_Default: current directory_)  
> The experiment name used for archival. The default setting uses the `control` directory name
