+## Liquid Clustering
+
+SQLMesh supports the liquid clustering keywords AUTO and NONE
+
+```sql
+MODEL (
+    name sqlmesh_example.new_model,
+    ...
+    clustered_by AUTO
+)
+```
+To cluster by a column called `auto` or `none`, use parentheses and backticks
+```sql
+MODEL (
+    name sqlmesh_example.new_model,
+    ...
+    clustered_by (`auto`)
+)
+```
