Hello I’m trying to get a centralised repository for ACCESS-ESM runs that use payu back in order. Because payu automatically updates the git history with each (changed) run, I think github should be the central location. I’ve started with collecting all the experiments that I know of here: [GitHub - coecms/access-esm: Main Repository for ACCESS-ESM configurations](https://github.com/coecms/access-esm) If you have other experiments, especially if they’re a descendent of the original (pre-industrial) ACCESS-ESM payu configuration, please let me know. (All ACCESS-ESM repositories from our github group except for ACCESS-ESM-AMIP are.) Thank you ---

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 > [@COSIMA TWG Meeting Minutes 2023](https://forum.access-hive.org.au/t/cosima-twg-meeting-minutes-2023/399/12): > > Notes from last week’s COSIMA TWG. Feel free to add whatever I’ve missed or to modify anything that I got wrong. Date : 2023-09-13 Attendees : Micael Oliveira @micael, Andrew Kiss @aekiss, Aidan Heerdegen @Aidan, Dougie Squire @dougiesquire, Angus Gibson @angus-g, Ezhil Kannadasan @ezhilsabareesh8, Siobhan O’Farrell @sofarrell, Jo Basevi @jo-basevi , Martin Dix @MartinDix ACCESS-OM3 Update 2 releases: 0.1.0: this mimics the CESM version we started with (over one year old) 0.2.0: updated to… 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 ---

That’s two really good recommendations. I’ll have a look at this.
