The typos in the text is in the command Update requirements.md

[mdqst]

The typo in the text is in the command:

node –-version

The dash used before version is an en dash (–) rather than a hyphen-minus (-), which is the correct character for command-line options.

Corrected version:

node --version

The same issue occurs with the npm command:

npm –-version

Corrected version:

npm --version

Fixed.
