 It's really common for students to, for any reader to stumble across something that you just, you don't have the background knowledge. This isn't something you're familiar with. And so it's, it's, I think, really helpful to be able to annotate through that jargon and to indicate how you, where you found information. When I have, when I ask students to make those types of annotations, I always have them cite the source for where they got the information. And so it's also a way of showing the, using your external resources, but then also in science it's always important that you, you cite your sources.
