How can i get the support document to check developer option in chrome setting

I'm unable to access external websites, but I can provide some general information about Chromium OS. Chromium OS is an open-source operating system designed by Google. It is the basis for Chrome OS, which is used in Chromebooks. The operating system is built around the Chrome web browser and is designed to be fast, simple, and secure, focusing primarily on web applications. If you have specific questions about Chromium OS, feel free to ask!
