# Installation & Setup

Three software projects comprise Old Faithful:

* [Faithful](http://github.com/rpcpool/yellowstone-faithful), used for running the [RPC server ](/usage/rpc-server.md)and [creating the necessary indexes](/running-old-faithful/sourcing-data/generating-from-rocksdb/creating-indexes.md) for the RPC server
* [Radiance](http://github.com/rpcpool/radiance-triton-faithful/), used for processing[ warehouse nodes’ ledger  archives and producing CAR files](/running-old-faithful/sourcing-data/generating-from-rocksdb/warehouse-nodes.md)
* [PoH check car,](https://github.com/rpcpool/poh-check-car) used for [validating PoH of Old Faithful](/usage/validation.md) car files.

You can also [interact with Old Faithful through standard Filecoin tooling](/running-old-faithful/installation-and-setup/configuration-files/filecoin-v1-retrievals.md) like [Lassie](https://github.com/filecoin-project/lassie).

You only need the Faithful CLI if you are interested in working with the Faithful dataset and retrieving data.
