+The next step is to create a sitepackage. In TYPO3, a sitepackage is a
+structured package that organizes the layout, design, and essential

+How to create a sitepackage
+===========================
 
+To create a sitepackage, you have two main options:
+
+*   Manual creation: For full control over your project's setup, you can follow
+    the detailed instructions int the
+    :ref:`TYPO3 site package tutorial <t3sitepackage:start>`.
+
+*   Using the `Sitepackage-Builder <https://www.sitepackagebuilder.com/>`__:
+    If you're looking for a faster start,
+    the Sitepackage-Builder is a handy tool. It builds on the
+    `Bootstrap Package <https://www.bootstrap-package.com/>`__
+    and provides a pre-configured setup with Bootstrap-based layouts and
+    elements, which you can further customize.

+Pros and cons of using the Sitepackage-Builder
+==============================================
+
+Pros:
+
+*   The Sitepackage-Builder is particularly useful for beginners or projects
+    that need a quick start. Since it's built on the Bootstrap framework,
+    it includes a wide range of ready-to-use, responsive components that can
+    save development time.
+
+Cons:
+
+*   Using a Bootstrap-based package may limit customization flexibility,
+    especially if your design requirements don't align with Bootstrap's
+    structure. For highly customized or non-Bootstrap designs,
+    a manual sitepackage might offer more freedom.
