   * :class:`.Interactions` - store inteactions for a single PDB structure
   * :class:`.InteractionsDCD` - store interactions for a trajectory
 
+Detect channels, tunnels and pores with CaviFinder
+====================
+
+Use the following to analyze cavities within protein structures
+in single PDB file or in trajectory:
+
+  * :func:`.getVmdModel` - generates a 3D model of proten, using VMD, which is then use for visualization
+  * :func:`.calcChannels` - computes and identifies channels
+  * :func:`.calcChannelsMultipleFrames` - compute channels for each frame in a given trajectory or PDB ensemble
+  * :func:`.getChannelParameters` - extracts and returns the lengths, bottlenecks, and volumes of each channel
+  * :func:`.getChannelAtoms` - generates an AtomGroup object representing the atoms along the paths of the given channels
+  * :func:`.showChannels` - visualizes the channels using Open3D
+  * :func:`.showCavities` - visualizes the cavities using Open3D
+
 Compare/align chains
