 ## Development
 
+### Running
+
+To run this generator, you also need to have [OpenAPI Forge] installed, or the repository checked out. Assuming you have it installed as a global module, you can run this generator as follows:
+
+```
+$ openapi-forge forge
+ \ https://petstore3.swagger.io/api/v3/openapi.json
+ \ .
+ \ -o api
+```
+
+This generates an API from the Pet Store swagger definition, using the generator within the current folder (`.`), outputting the results to the `api` folder.
+
 ### Testing
 
 The standard test script is used to execute the BDD-style tests against this generator.
