-Note:
-- **This is an untested Payu configuration for an untested CESM configuration**. This configuration is adapted from an officially-unsupported CESM configuration (The CIME GMOM_JRA_WD "compset").
-- This configuration uses a Payu driver that does not currently exist in the main Payu repo. We're working to include it, but in the meantime those wanting to play with this configuration will need to use the version of Payu in [this](https://github.com/dougiesquire/payu/tree/cesm_cmeps) branch.
-- No effort has (yet) been put into optimising the PE layout of this configuration on Gadi - currently each model component simply runs sequentially and is allocated an entire node.
-- The execuatable used by this configuration was built using CIME (see [here](https://forum.access-hive.org.au/t/cesm-configurations-on-gadi-using-cime/115) for setup details):
-  ```bash
-  cd cime/scripts
-  ./create_newcase --case my_case --compset GMOM_JRA_WD --res T62_g16 --machine gadi --run-unsupported
-  cd my_case
-  ./case.setup
-  ./case.build
-  ```
-- By default, this configuration will advance 1 month per model run
+This configuration is adapted from an officially-unsupported CESM configuration
+(The CIME GMOM_JRA_WD "compset"). It was generated using a fork of
+[CESM](https://github.com/COSIMA/CESM) with following commands:
+```bash
+git clone https://github.com/COSIMA/CESM
+cd CESM/cime/scripts
+./create_newcase --case my_case --compset GMOM_JRA_WD --res T62_g16 --machine gadi --run-unsupported
+cd my_case
+./case.setup
+```
+The configuration was then adapted to run with ACCESS-OM3 using payu.
