 By default, auto sell is enabled. If you want to disable it, you need to:
 - Change variable `AUTO_SELL` to `false`
 - Update `MAX_SELL_RETRIES` to set the maximum number of retries for selling token
+- Update `SELL_DELAY` to the number of milliseconds you want to wait before selling the token
+  - This will sell the token after the specified delay. (+- RPC node speed)
 
-Token will be sold immediately after it is bought.
+If you set SELL_DELAY to 0, token will be sold immediately after it is bought.
+
+There is no guarantee that the token will be sold at a profit or even sold at all. The developer is not responsible for any losses incurred by using this feature.
 
 ## Common issues
 If you have an error which is not listed here, please create a new issue in this repository.
