 ## Running the benchmarks
 
+The repository contains a set of benchmarks that can be run locally or remotely using `coiled`. The benchmarks are run using the `main.py` script. The script takes the following arguments:
+
+```bash
+$ python main.py --help
+usage: main.py [-h] [--runs RUNS] [--detect-provider] [--approach APPROACH] [--dataset DATASET]
+               [--zarr-version ZARR_VERSION] [--non-headless] [--s3-bucket S3_BUCKET] [--action ACTION]
+               [--zoom-level ZOOM_LEVEL]
+
+options:
+  -h, --help            show this help message and exit
+  --runs RUNS           Number of runs to perform
+  --detect-provider     Detect provider
+  --approach APPROACH   Approach to use. Must be one of: ['direct-client']
+  --dataset DATASET     dataset name. Must be one of: ['1MB-chunks', '5MB-chunks', '10MB-chunks', '25MB-chunks']
+  --zarr-version ZARR_VERSION
+                        Zarr version. Must be one of: ['v2', 'v3']
+  --non-headless        Run in non-headless mode
+  --s3-bucket S3_BUCKET
+                        S3 bucket name
+  --action ACTION       Action to perform. Must be one of: ['zoom_in', 'zoom_out']
+  --zoom-level ZOOM_LEVEL
+                        Zoom level
