+### Custom field types
+
+You can use custom field types in your models by providing a set of custom types to the commands:
+
+```clojure
+;; Using with make command
+(make {:custom-types #{:dml-type}})
+
+;; Using with migrate command
+(migrate {:custom-types #{:dml-type}})
+
+;; Using with explain command
+(explain {:number 7 
+          :custom-types #{:dml-type}})
+
+;; Using in models.edn
+{:users-change-history 
+  {:fields [[:changed-dml :dml-type {:null false}]]}}
+```
+
+Note: The custom type must be already defined in your database before using it in migrations. For example:
+
+```sql
+CREATE TYPE dml_type AS ENUM ('INSERT', 'UPDATE', 'DELETE');
+```
