Suggestion for a wording correction on the Debian website

Dear Debian Web Team,
I would like to report a small problem related to the language on the Debian website.
On the page https://www.debian.org/intro/why_debian, there is a sentence that says:
“Debian is made of free and open source software.”
That is fine, but a better English expression would be:
“Debian is made up of free and open source software.”
"Made up of" is preferable for abstract things such as software.
Once again, I thank you for everything you do and the effort put into maintaining such a valuable project.
Best regards,
Enea
