-<p>The <a href="https://swift.org/package-manager/">Swift Package Manager</a> is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but UserDefaultsStore does support its use on supported platforms.</p>
-<p>Once you have your Swift package set up, adding UserDefaultsStore as a dependency is as easy as adding it to the dependencies value of your Package.swift.</p>
+<p>You can use <a href="https://swift.org/package-manager">The Swift Package Manager</a> to install <code>UserDefaultsStore</code> by adding the proper description to your <code>Package.swift</code> file:</p>
 
 <pre><code class="swift language-swift">import PackageDescription
-dependencies: [
-    .package(url: "https://github.com/omaralbeik/UserDefaultsStore.git", from: "1.0.2")

+    ]
+)
 </code></pre>

+<p>Next, add <code>UserDefaultsStore</code> to your targets dependencies like so:</p>
