Websites for Foreigners to Learn Portuguese

What is up, guys?!

I've been asked for some American co-workers about websites for them to learn, receive hints, check out pronunciation and all that when it comes to Portuguese.

Looking up differently over Google always surrounding the theme "Portuguese for Foreigners", I didn't find too much, even tried Youtube channels, didn't have any luck.

I'm wondering if any of you has been ever asked for something alike and would know cool stuff regarding to this subject.

Any tiny help on it will be much appreciated !

Hope you all have a great rest of weekend. Peace out.
