Hello, author here: thank you for your feedback!

In general, I've removed the notes in the brackets and either added more context and examples or integrated it into the text.

> Scheme: (always present, not always visible)

Added more context.

> Path: (always present)

You are right, the root directory `/` is implied. Added this as an example.

> It is recommended to place IPv4 and IPv6 addresses into brackets:

Correct, my bad. I've added more examples and the note, that it is required to put IPv6 addresses into square brackets.

> Host: (always present, not always visible)

Been a while so I am not sure what I meant. I've made some changes and added more examples.

Again, thank you!
