## Contributing

As you know stocks in an index get change and keeping that up to date is not a one person job, that's why i have made all this configurable.
There are 2 folders "./NSEIndexConfigs"  and "./BSEIndexConfigs" in which all the index stocks configuration are present eg. Auto, Nifty50, BSE100 etc.

You can make changes to config by adding/removing the stock as per NSE and BSE changes or create the new/customized config and raise the pull request.

Also there is "./src/config.json" in which UI related config are present.

Inputs are always welcome! whether it's.

- Discussing the current state of the code
