+summary: Blender is the free and open source 3D creation suite.
+description: |
+    Blender is the free and open source 3D creation suite. It supports the
+    entirety of the 3D pipeline—modeling, rigging, animation, simulation,
+    rendering, compositing and motion tracking, and video editing.
+
+    Blender is a public project, made by hundreds of people from around the
+    world; by studios and individual artists, professionals and hobbyists,
+    scientists, students, VFX experts, animators, game artists, modders, and
+    the list goes on.
+
+    The standard snap channels are used in the following way:
+
+           stable - Latest stable release.
+        candidate - Test builds for the upcoming stable release.
