+### About Merged Point Visualizations
+
+By setting `point-merge-grid-cell`, a tolerance may be defined which allows merging the visual representations
+of point features which share the same 3D spatial cell, map, layer, and style rule. This has two advantages:
+
+* **Multi-Selection**: When selecting the merged representation, a multi-selection of all merged features happens.
+* **Logical Evaluation using `$mergeCount`**: In some map formats, it may be desirable to apply a style based on the number of merged points.
+  This may be done to display a warning, or to check a matching requirement.
+  To this end, the `$mergeCount` variable is injected into each simfil evaluation context of a merged-point style rule.
+  Check out the default style for an example.
+
 ### About `first-of`
 
 Normally, all style rules from a style sheet are naively applied to all matching features.
