-For example, on port 8090
+You can run SuSy dApp extractor
 
 ```
 docker run -itd -p 8090:8090 gravityhuborg/gravity-data-extractor:master
 ```
 
+### 2.1 Run SuSy dApp extractor for EVM-based or WAVES-based chains
+
+Currently, extractor supports only `EVM-chain<->WAVES` direction.
+So we in order to add new custom(non-EVM) chain we need to provide 4 additional params
+and 2 bridge implementations as well - for direct and reversal swaps.
+
+So, for EVM-based tokens we run `--waves-based-to-eth-direct` and `--waves-based-to-eth-reverse`.
+For WAVES-based tokens we run `--eth-based-to-waves-direct` and `--eth-based-to-waves-reverse`
