+## Trying a change before it's released
+
+Every push to a branch here publishes a preview of the package, which you can
+install anywhere — no npm release, no `npm link`:
+
+```
+npm i https://pkg.pr.new/datocms/astro-datocms/@datocms/astro@<commit-sha>
+```
+
+The exact URL shows up in the commit's check run on GitHub, and in a comment on
+the pull request once there is one. This is the supported way to try a change
+inside a site that lives in another repository, or to hand a fix to whoever
+reported it before it is released.
+
+Previews are throwaway: they are never published to npm, and the URL stops
+resolving after a while. Never commit one to a `package.json` that ships.
