Hey @sidmohanty11 please remove the hook. thanks.

[debdutdeb]

Why not put the configs on the top level?

[sidmohanty11]

@debdutdeb we can't do it with eslint as its configs are different for app and cms, but as far as I know, prettier will go up one dir and search for the config till it finds one, so we can definitely use it from the top level. I've made the changes, please let me know if something else needs to be changed.

Thanks!
