• Install 1.2 or later versions from release
• Launch Blender and select the Zip file downloaded by Install from Edit/Preference/Add-ons
• Enable "realistic terrain"
  
• The toolbar will then appear here
  

Tutorial

Process erosion for terrain mesh generated with A.N.T.Landscape

• Create an A.N.T. Landscape grid with a resolution of 1024x1024 (be sure to create the grid with NxN resolution)
  
• Run simulations from Terrain/Erode/Process
  
  
• Create a grid with size 2.0 and resolution 1024x1024 from Terrain/Grid/Create (A.N.T. Landscape meshes are not UV expanded, and high-resolution grids take time to expand, so create a pre-expanded grid)
• Apply Shrinkwrap to copy grid vertex height information
  
• Select the grid from which the height information was copied and attach TerrainMaterial
  
  
• Adjust parameters to complete
