1. When creating a new export, click on the new button **“Manually set source format.”**

2. You are now on a page where you **“map” elements** from your input (unknown to Mergado) feed to Mergado. To understand why this step is a little more complicated, we have tried to describe it easily.

1. Name the new feed.

2. Click Save. It redirects you back to a known page where you specify the input and output feed. At the input, you will have a set and named feed set by you. And on the output, you classically choose the format as needed.
