+MUST READ: Angular CLI - Latest Version
+Section 1, Lecture 5
+Important: In the next lecture, we'll use a tool called the "Angular CLI" to create our Angular project.
+
+With the latest version, this tool will ask you two questions:
+
+1) Do you want to use the Angular Router?
+
+2) Which CSS pre-processor do you want to use?
+
+Simply hit ENTER twice and confirm the default (without entering any value).
+
+The defaults (which we will use therefore) are:
+
+1) No (No router for now, we'll add it later)
+
+2) CSS

+Using MongoDB Atlas & IP Whitelist
+Section 4, Lecture 48
+By selecting the "Free Sandbox" in the previous video, we're using MongoDB Atlas (https://www.mongodb.com/cloud/atlas) in this course - a hosted MongoDB cluster.
+
+There, we added our local IP to the "IP Whitelist". One important note on that: If you're away from the project for a couple of days (or maybe even after one day), you might've received a new local IP by your internet provider. Hence you should update that "IP Whitelist" if you're facing any connection issues!
