# Custom Config Support

## BSSH Run Planner Setup

On the **BSSH Run Planner**, custom parameters and custom resource files can also be specified during Run Planning.

**Custom resource files** must be uploaded to BaseSpace under the same project to be selectable during run planning. Supported customizable options are described in the Custom Configuration Support section of each application.

See [Uploading Reference Files to BaseSpace](https://help.basespace.illumina.com/sequence/plan-runs/multi-analysis-planned-run/reference-files) for additional details.
