# release

The Mini Program will review the statement at the arraignmentsupportedMaterialsWhether the Mini Program is compliant or not, the Mini Program will appear after the corresponding file type opens the entrance.

If the function value of the Mini Program is low, it will not be approved, including but not limited to the following circumstances:

The function after opening the Mini Program has nothing to do with the corresponding material: it just opens its own Mini Program through this entrance, and does not do any processing to the material.
The way to handle the material after opening the Mini Program is too simple: just play a video or just view a.docx file, such as simple functions that can be achieved through WeChat chat.

Please developers with their own Mini Program functions and user needs to adapt.
