+Configure npm to use packages from @lsst-sqre
+---------------------------------------------

+Although they're publicly-available, you will need a `GitHub Personal Access Token <https://github.com/settings/tokens/new>`__ with ``read:packages``.
+
+Add an `@lsst-sqre` registry entry to your `~/.npmrc` file using the token you created::
+
+    @lsst-sqre:registry=https://npm.pkg.github.com/
+    //npm.pkg.github.com/:_authToken=<...>
