- Removed hedging between "your applications" and "or third party software" to increase confidence by reducing indirection; third-party applications is already mentioned in the details as well and redundant.
- Emphasized "Hit" verb by starting the sentence with it.
- Swapped "specialized" for "custom" to remove ambiguity and emphasize the user/developer's role in setting up the software.
