0.10.2: sphinx warnings `reference target not found`

Tái hiện báo cáo bằng sphinx-build -n -T -b man docs build/sphinx/man, sau đó kiểm tra các docstring được tham chiếu trong tomlkit/init.py, tomlkit/items.py và tomlkit/toml_document.py cùng với cấu hình tài liệu. Hoàn thành khi quá trình build không còn phát ra các cảnh báo missing-reference, duplicate-description và thiếu _static đã được báo cáo.

On building my packages I'm using sphinx-build command with -n switch which shows warmings about missing references. These are not critical issues.
Here is the output with warnings:
