The operation and promotion of small programs complement each other. Only when someone helps you can people flow, and someone can flow to the operational level. Running a small program is quite complicated and boring. You even need to make a set of all possible project brain maps at the beginning of the project to adjust this strategy, such as what your applet portrait is, your user preferences, where users are, and how to reverse drainage. How to make them use it every day is a problem you should consider. If you have to say where to start, please start with positioning first.
Locate your fans and know where your fans or users are, and you will succeed in a small part. The next step is the Taoist artifact level. You have made it very clear that magical devices are nothing more than your tools, your means and other operational things, which is quite important for an inexperienced practitioner.
