+        <p>
+          Nix builds packages in isolation from each other. This ensures that they
+          are reproducible and don't have undeclared dependencies, so <strong>if a
+            package works on one machine, it will also work on another</strong>.

+        <p>
+          Nix makes it <strong>trivial to share development and build
+            environments</strong> for your projects, regardless of what programming
+          languages and tools you’re using.

+        <p>
+          Nix ensures that installing or upgrading one package <strong>cannot
+            break other packages</strong>. It allows you to <strong>roll back to
+            previous versions</strong>, and ensures that no package is in an
+          inconsistent state during an upgrade.
