+For instance, we can see this organization in the wild by using rstac to explore a public STAC API. Microsoft hosts a STAC API as part of their [Planetary Computer](https://planetarycomputer.microsoft.com/); we'll use their API for the rest of this tutorial.
 
 To start downloading data, we’ll first need to let rstac know what STAC
 API we want to query and download from. To do so, we’ll pass the URL of
