Niche software, raised this problem, the original post address is as follows: http://www.appinn.com/discuss-software-information/

Original question: I would like to ask you a question. When you use a software, what information do you usually want on its official website or user forum?

My simplified solution is as follows:

As a user who is hesitant to download or use it, what you want to know most is:

Main functions and special functions of the software;

You can see the interface design and basic operations through an animated demonstration;

The overall evaluation and comparison evaluation of the software by trustworthy users;

Is there any portable or installation-free version;

Performance in terms of stability, compatibility, and resource occupation;

As a beginner, the following information is most desired:

Getting started with text, images, and videos;

Basic configurations and common configurations;

Answers to some basic questions;

As a skilled user, I hope to have:

Introduction of practical plug-ins and supporting software;

Interface beautification introduction;

Configuration details, especially those software with rich configuration options and confusing annotations;

Advanced usage skills, such as the shortcut key list, implementation of special functions, and manual configuration;

Discuss the functional limits of software;

Channels for submitting comments and suggestions to the manufacturer;

Update notifications and changes of the new version;
