2. git clone https://github.com/hpoenixf/open-etf-agent open-etf-agent && git -C open-etf-agent checkout dad9c6e64f32c3d7579aea96613776b40917ec6d
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./open-etf-agent --url http://127.0.0.1:9200 --prefix open-etf-agent --progress plain
5. xerj autoindex map --url http://127.0.0.1:9200
