+# Running Slabplanet
+The `run_amip.jl` driver contains two modes: the full AMIP mode and a Slabplanet mode, where all surfaces are thermal slabs. Since AMIP is not a closed system, the Slabplanet mode is useful for checking conservation properties of the coupling.
+
+Running a Slabplanet simulation is the same as running an AMIP simulation, except for the specifics of the configuration file provided, so all information from the `Running AMIP` section will apply here too. Note that the default configuration used by `run_amip.jl` specifies an AMIP simulation, so a configuration file must be specified to run a Slabplanet simulation. This can be done as follows:
+```julia
+julia --project=experiments/ClimaEarth experiments/ClimaEarth/run_amip.jl --config_file config/ci_configs/slabplanet_default.yml --job_id slabplanet_default
+```
+
+To ensure that conservation is tracked throughout the experiment, the `energy_check` field of the configuration file must be set to true.

-`SlabPlanet` mode is useful for checking conservation properties of the coupling.
+## Running the AMIP configuration
+To run a coupled simulation in the default AMIP configuration, run the
+following command from the root directory of the repository:
+```bash
+julia --project=experiments/ClimaEarth experiments/ClimaEarth/run_amip.jl
+```
+
+## Configuration
+You can also specify a custom configuration file to run the coupled simulation
+in a different setup. The configuration file should be a TOML file that overwrites
+the input fields specified in `experiments/ClimaEarth/cli_options.jl`.
+A set of example configuration files can be found in the `config/ci_configs/` directory.
+
+For example, to run the coupled simulation with a different configuration file:
+```bash
+julia --project=experiments/ClimaEarth experiments/ClimaEarth/run_amip.jl --config_file="path/to/config.toml"
+```
+
+To run the coupled simulation interactively with a different configuration file,
+set the `config_file` variable in this script to be the path to that file.
+
+For more details about running a coupled simulation, including how to run in a
+Slabplanet configuration, please see our [README.md](https://github.com/CliMA/ClimaCoupler.jl/blob/main/README.md).
