+# Ignition Visualization Marker Example
+
+This example demonstrates how to create, modify, and delete visualization
+markers in Ignition GUI.
+
+## Build Instructions
+
+From this directory:
+
+    mkdir build
+    cd build
+    cmake ..
+    make
+
+## Execute Instructions
+
+Launch ign gazebo unpaused then from the build directory above:
+
+    ./marker
+
+The terminal will output messages indicating visualization changes that
+will occur in Ignition GUI's render window.
