+Other add-ons
+=============
+
+Blender has a large ecosystem of add-ons. The BlenderBIM Add-on is one of many
+add-ons which provide utility to the architecture, engineering, and construction
+industry.
+
+Some of these add-ons come with Blender and merely need to be enabled in the
+``Edit > Preferences > Add-ons`` tab.
+
+- **Sun Position** - will allow you to set the correct location of the sun and
+  true north. Integrates with IFC4 georeferencing features in the BlenderBIM
+  Add-on.
+- **AutoCAD DXF Format (.dxf)** - provides import and export support of the DXF
+  format in Blender.
+- **tinyCAD Mesh tools** - provides basic intersection and circle reconstruction
+  utilities similar to trim / extend / centroid tools in CAD tools.
+
+Some of these add-ons are not shipped with Blender:
+
+- `CAD Transform for Blender <https://gumroad.com/l/nqvcs>`__ - This will
+  provide CAD snapping, move, rotate, and scale functions in Blender. This is
+  highly recommended for precision modeling in Blender.
+- `Blender Archipack <https://blender-archipack.org/>`__ - Archipack lets you
+  create parametric architectural objects, like walls, floors, ceilings, doors,
+  roofs, and furniture with a single click from a preset templates. It
+  integrates with the BlenderBIM Add-on, so you have the choice to combine both
+  parametric and modeling by hand.
+- `Sverchok <https://github.com/nortikin/sverchok/>`__ - Sverchok is a visual
+  programming add-on for Blender that allows you to generate parametric
+  geometry, create scripts for non-programmers, model solids from FreeCAD, and
+  much more.
+- `BlenderGIS <https://github.com/domlysz/BlenderGIS>`__ - BlenderGIS lets you
+  import GIS data, grab elevation data from the web, and generate TINs from
+  survey points and contours.
+- `Ladybug Tools for Blender
+  <https://blenderbim.org/builds/ladybug-blender-220127.zip>`__ - Ladybug Tools
+  is an extension of Sverchok for environmental analysis and building physics
+  simulation. It allows analysis of solar, daylight, energy, and CFD.
+- `Topologic <https://topologic.app/>`__ - Perform spatial and topological
+  analysis of simplified building geometry and space connectivity.
+- `Speckle Blender <https://speckle.systems/tag/blender/>`__ - Use Speckle to
+  get your designs in Blender from other CAD software.
+- `Point Cloud Visualizer <https://blendermarket.com/products/pcv>`__ - Display,
+  edit, filter, render, convert, generate and export colored point cloud PLY
+  files.
+- `MeasureIt_ARCH <https://github.com/kevancress/MeasureIt_ARCH>`__ - Simple
+  dimensioning and annotation tools in Blender.
+- `Sorcar <https://aachman98.itch.io/sorcar>`__ - Another visual node
+  programming alternative to Sverchok.

 Installation
 ============
 
+If you'd like to work with the C++ core of IfcOpenShell, these guides will show
+you how to compile and install IfcOpenShell.
+
+.. note::
+
+    It is not necessary to compile IfcOpenShell if you only want to use
+    IfcOpenShell-Python, IfcConvert, or the other utilities such as IfcClash or
+    IfcDiff. Compilation is only necessary for C++ developers.
+
 You will need:
 
 - `Git <https://git-scm.com/>`__
