 Here's an example for getting the information out of a Release file:<br>
 ```ts
 import axios from 'axios';
-import { parseRelease } from 'apt-parser';
+import { Release } from 'apt-parser';
 
 const { data } = await axios.get('http://archive.ubuntu.com/ubuntu/dists/jammy/Release');
-const releaseMap = parseRelease(data);
+const release = new Release(data);

-console.log(releaseMap.get('Version')); // => 22.04
+console.log(release.origin); // => Ubuntu
+console.log(release.version); // => 22.04
 console.log(releaseMap.get('InvalidKey')); // => null
 ```
 
+A full Release object has the following properties attached on it, all of which map to documented APT fields.<br>
