Step by Step

Twillo is a web-based platform that can be used free of charge. You can access it from all web-enabled devices.

If you want to search for and download material, you can do so without your own account. On the homepage, you will find a search bar and icons that filter by the most relevant subject areas.

For example, if you are interested in OER from the field of engineering, then clicking on the icon will open the pool with materials on this topic. On the left-hand side, you can narrow down your search further and filter by language, subject, or type of material.

After selecting a material, you will find all the important information about licenses and authors, as well as a description of the level for which the material can be used and which technical requirements must be met. You can now download the material using the button in the top right-hand corner.

You need an account to publish your own materials on twillo. You can create a manual account or log in via single sign-on with your campus ID.

After logging in, click on the +NEW button and then select the New Material option.
