+Configuration options for each component are located in `framework/src/component/<component-name>/defaults/config.js`.
 
-It holds the variables and constants critical for the whole application, possibly affecting other modules. For now, those are: "os", "version", "wsPort", "httpPort", "minVersion", "protocolVersion", "height", "nethash", "broadhash" and "nonce".
