What key feature should be included in adoption support materials?

Including clear instructions and resources for troubleshooting common issues in adoption support materials is crucial because it empowers users to handle challenges independently and effectively. This feature ensures that users have readily accessible guidance that addresses potential problems they may encounter, fostering a smoother adoption experience.

By providing comprehensive troubleshooting resources, the support materials enhance user confidence and satisfaction, helping to reduce frustration during the transition period. This leads to a better overall user experience, as they feel equipped to resolve issues without needing to seek external help.

The other options, while they may have their own merits, do not directly support the immediate needs of users in navigating and utilizing the service effectively. For example, supplementary software for troubleshooting may not be as practical if users struggle with initial adoption. A detailed history of the service's development might be interesting but does not assist users in troubleshooting. Similarly, a list of competitive services does not provide the necessary support users need when they are experiencing issues. Focusing on clear instructions and resources ensures that the primary objective of assisting users through their adoption journey is met.
