+N.B. Test data must be created in the following way (TODO: finish):
+* Install <https://github.com/cardano-foundation/testnet-generation-tool>
+* Use it to generate testnet config files (no need to deploy testnet)
+* Fix the config.json by hand for some fields ("LedgerDB", "DijkstraGenesisFile") by looking at recent config files in cardano-node and ouroboros-consensus
+* Use db-synthesizer (from <https://github.com/IntersectMBO/ouroboros-consensus>) to generate a db using the config and keys generated by testnet-generation-tool.
+
+Testnet-generation-tool command used:
+
+```
+python3 genesis-cli.py example-config-testnet.yaml -o ../db-server/test-data/10.5.1 -c generate

 # Usage
 
 `db-server` can be used in two modes: as an HTTP server exposing some endpoints over an existing cardano-node DB, or as command-line query tool.
