To Moderators/Community manager,
The link to 'Installation Guide' in the pinned message (link provided below) is dead.
It will be helpful if you update it at the earliest.
You can visit this link instead: https://devdocs.magento.com/guides/v2.4/install-gde/composer.html
Pay attention to Magento 2 Installation Preparation Requirements here as well
Hope it can help you. Have a nice day.
