#### **How to: Browse the workshop catalog**
You can browse the Workshops Catalog in either of two ways:
- From the **hero on the homepage**: click/tap on the **Workshops button** in the hero section and you will be taken to the Workshops Catalog
- From the **Workshops menu on the navigation bar or mobile menu**: expand the Workshops menu and click/tap on **Register for Workshops** in the dropdown
Once you are on the Workshops Catalog page, you will be able to **Choose a Category** from the multiple categories that are available (for the ITLL these include: Arduino, CAD, ECAD, Electronics, Manufacturing, Materials Testing, Programming, Prototyping, and Tour).
1. Click/tap on one of the workshop categories at the top under **Choose a Category**.
2. Next, click/tap on one of the workshops available under **Choose a Workshop**. Sometimes there may be a Level 1 through 4 series of a workshop available, in which case the Level 1 workshop may be a prerequisite for the Level 2 workshops or higher.

- If a workshop has a prerequisite that you haven't yet met, you will see indicator text both within the Description and also in the Review & Register section (which will both list the title of the Prerequisite event), and you will be unable to click/tap on the Register button.
