 ### Generators
 
-##### JHipster Entity Generator

+ - Import JDL - `ignite generate import-jdl <jdl-filename>`
+    - Import several entities at once using JDL
+    - Runs the entity generator for each entity present in the JDL
+ - Upgrade - `ignite generate upgrade`
+    - Upgrades your generated app to the latest template code
