The gatsby-image plugin has been deprecated in favour of the gatsby-plugin-image. The How-to guide still references the deprecated plugin, with a short 2-sentence note between a large table of contents and the bulk of the documentation.
If you’re like me, you see the title of the page you want, and then dive straight into the examples, then the comparatively small entry, with no title, is easily missed.
I think it would be helpful to update the documentation to use the newer plugin.
Or, as a minimum, to give the deprecation notice a prominent heading.
