Most pages on this site provide both a human-readable version (HTML) and a machine-readable version (JSON; although it is also pretty easy for humans to understand). Which version is returned depends on the Accept header in the HTTP request. Normally, if you access the page through a web browser you should get the HTML version, while Sumatra or compatible tools will receive the JSON version. You can also override the Accept header by explicitly adding ?format=html or ?format=json to the end of the URL.
