+To start, we generate placements for the reactant and product species on the surface. We utilize the random placement approach which was developed for AdsorbML, and use an OCP model to relax our placements on the surface. These placements and their ML-determined energies are used as input to the CatTSunami automatic NEB frame generation approach.

+### Run ML local relaxations:
+
+There are 2 options for how to do this.
+ 1. Using `OCPCalculator` as the calculator within the ASE framework
+ 2. By writing objects to lmdb and relaxing them using `main.py` in the ocp repo
+
+(1) is really only adequate for small stuff and it is what I will show here, but if you plan to run many relaxations, you should definitely use (2). More details about writing lmdbs has been provided [here](https://github.com/Open-Catalyst-Project/ocp/blob/main/tutorials/lmdb_dataset_creation.ipynb) - follow the IS2RS/IS2RE instructions. And more information about running relaxations once the lmdb has been written is [here](https://github.com/Open-Catalyst-Project/ocp/blob/main/TRAIN.md#initial-structure-to-relaxed-structure-is2rs).
+
+You need to provide the calculator with a path to a model checkpoint file. That can be downloaded [here](../core/model_checkpoints)
