Embedding assets is straightforward. First, upload your media to Contentful. You can do it through the Media tab, or directly in the editor of an entry. Then, select the asset you’d like to add to your entry, and link.
Through the Media tab:
Click the Media tab in the top navigation bar.
Click the Add asset button.
Select whether you want to upload a single asset or multiple assets.
You can either drag and drop your media file into the window or select it from your computer.
In the Editor:
Navigate to the entry you want to embed an asset in. Click the + Embed button and select Asset.
If your asset has already been added, you can select it from the dialog that appears. If not, click “+ Create new asset” and upload your file.
When finished, the asset will appear in the body of your entry.
