2. Explanation of key locations

[Tasks] The code segment flags: unchecked is selected by default.
[Files] Adding Check: isneedinstall in the code segment is a judgment to check whether the code is processed. isneedinstall is a function customized in the [Code] code segment.

[Run] After the code snippet flags is installed with an unchecked, this option is not checked. This option is not selected by default.
