 Development Guide
 =================
+
+Background Knowledge
+--------------------
+
+NG-SDN Tutorial
+^^^^^^^^^^^^^^^
+We highly recommend people to go through the **NG-SDN Tutorial** as preparation for the SD-Fabric development work.
+You will learn all the required background knowledge and get opportunities
+to run hands-on experiments as part of the tutorial.
+The tutorial is free and publicly available at: https://github.com/opennetworkinglab/ngsdn-tutorial
+
+Reading Materials
+^^^^^^^^^^^^^^^^^
+- `SD-Fabric Techinar 2021 <https://opennetworking.org/events/sd-fabric-techinar/>`_
+
+  Introduction to the SD-Fabric project.
+
+- `Software-Defined Networks: A Systems Approach <https://sdn.systemsapproach.org>`_
+
+  Book about SDN in the context of P4, Stratum ONOS, whitebox switches, etc.
+  Even if you are already familiar with most of the concepts,
+  it should give you “full-stack” view of how we use programmable data planes at ONF.
+
+- `5G Mobile Networks: A Systems Approach <https://5g.systemsapproach.org>`_
+
+  Same as the SDN book but related to 5G architecture, a very good starting point to
+  get aligned with other ONF engineers around architecture and terminology for mobile networks.
+  Optional if your work will not be strictly related to Aether.
+
+- `Aether overview <https://youtu.be/ZzwFQCSmOJg>`_
+
+  There are many videos available on YouTube, this one should be the most recent.
+  Optional if your work will not be strictly related to Aether.
+
+- UP4 architecture
+
+  UP4 is the codename for our P4-based UPF project. Optional if your work will not be strictly related to Aether.
+
+  - `Blog post (Sep 2021) <https://opennetworking.org/news-and-events/blog/using-p4-and-programmable-switches-to-implement-a-4g-5g-upf-in-aether/>`_
+  - `Paper (Sep 2021) <https://www.cs.princeton.edu/~macdavid/media/up4-sosr21.pdf>`_
+  - `Slide deck <https://docs.google.com/presentation/d/1IlxsGKXPtqfFFAqORZV-N5OuCvoLloXQuKjvaL5Xf7M>`_
+
+- `Trellis architecture <https://docs.trellisfabric.org/1.12/architecture.html>`_
+
+  This document is based on an outdated, OF-DPA based data plane. But the control plane design logic remains the same.
+
+.. note::
+  We are working on development guides for ``fabric-tna`` pipeline and SD-Fabric control applications (``SegmentRouting``, ``UPF``, ``INT``).
+  More contents will be available shortly.
