# Overview

### Users, Activities and Enrolments

There are three main concepts that drive the delivery of learning within **ClearXP** – users, activities and enrolments.

There's little doubt that you're familiar with the concept of **Users**, after all, you're a user yourself. However, it's worth mentioning that users represent your audience and that profile information such as a position title, department, or the user's geographic location help differentiate audience groups.

**Activities** is a broad and all-encompassing term for everything on the platform that a user may interact with. Most commonly this is a piece of learning content, but it's also inclusive of things both smaller and larger – a quiz question, a notification, a learner's objectives, even the platform itself is a type of activity.

Less glamorously are **Enrolments**. Just as rivers bridge the mountains and the sea, enrolments are used to connect users with activities. When you create an enrolment, you are stipulating that a user should complete some piece of learning at some point in time. An enrolment may be used to enforce compliance training or more loosely, it may simply suggest some content to your user base. Of course, learners may also elect to undertake some learning themselves – this is known as a *self-registered* enrolment – but more on that later.

### The Learning Hub

After you've created an enrolment, your users need some way to find the learning that you've assigned to them. They can do this by accessing the *Learning Hub*.

The Learning Hub is like an atlas, road map and compass all rolled into one. Learners can use it to see and complete the mandatory learning assigned to them, or they can use it to explore and discover new content. Managers can use the Learning Hub to follow up on their team or manage approval tasks assigned to them.
