 ##### Tree Inventory Configuration
 
+The tree inventory configuration supports three data sources:

+1. **TreeMap** (default): Nationwide tree data from USFS TreeMap
+2. **Point Cloud**: ALS-derived trees from 3DEP point cloud data
+3. **File Upload**: Your own tree inventory from a CSV file

+- `TREE_ID` (Integer): Unique identifier for each tree
+- `SPCD` (Integer): FIA species code
+- `STATUSCD` (Integer): Tree status (1: Live, 2: Dead, etc.)
+- `DIA` (Float): Diameter in cm
+- `HT` (Float): Height in meters
+- `CR` (Float): Crown ratio (0-1)
+- `X` (Float): X coordinate in projected CRS
+- `Y` (Float): Y coordinate in projected CRS

 #### Configuration Tips
 
 1. **Partial Overrides**: Only specify the parameters you want to change. The function will merge your configuration with sensible defaults.

+## Using the Convenience Function
+
+You can also use ALS point cloud data through the `export_roi()` convenience function by specifying `"pointcloud"` as the tree inventory source:
+
+```python
+from fastfuels_sdk import export_roi
+
+tree_inventory_config = {
+    "source": "pointcloud",
+    "pointCloudSources": ["3DEP"]
+}
+
+export = export_roi(
+    roi=roi,
+    export_path="als_export.zip",
+    tree_inventory_config=tree_inventory_config,
+    verbose=True  # Recommended - point cloud processing takes longer
+)
+```
+
+This handles the entire workflow (point cloud creation, tree inventory, grids, and export) in a single function call.
