+**What it does**
+
+This tool performs graph-based tree instance segmentation on LiDAR point clouds using the **RayExtract** algorithm (Devereux et al., 2026) implemented as part of **RayCloudTools** (Lowe &amp; Stepanas, 2021). 
+It is platform-agnostic and works across airborne (ULS), terrestrial (TLS), and mobile (MLS) laser scanning data, as long as trees are well-represented by points along the entire tree length.
+  
+-----
+
+**Processing Steps**
+
+- Convert input point cloud to LAZ 1.2
+- Import point cloud as ray cloud
+- Extract terrain
+- Extract trees
+- Convert point color (segmentation result) to instance IDs
+- Add instance IDs back to input point cloud  
+
+-----
+
+**Output**
+
+Original LAZ point cloud + instance IDs in extra dimension 'PredInstance'.
+
+***Tip:** We recommend using the '3DTrees: Tile and Merge' or '3DTrees: Smart Tile' tool to process large point clouds (workflow: tile → segment → merge)!*
