This tool is intended to be a simple, stateless, self-hosted explorer for the Bitcoin blockchain, driven by RPC calls to your own bitcoind node. Because it is stateless, it is easy to run but lacks some (many?) of the features of other explorers.
1. Install and run a full, archiving node - [instructions](https://bitcoin.org/en/full-node). Ensure that your node has full transaction indexing enabled (`txindex=1`) and the RPC server enabled (`server=1`).
