+### auto fetch
+1. install the package
+2. create config files for every microservice that you need (put it in the root project folder for example openapiEvents.config.json)
+3. inside the config file you need to specify
+   1. output folder (for Events it would be ./src/shared/api/events)
+   2. microservice that you're specifying ("Events")
+   3. environment that using for fetch ("feature")
+   4. if you don't want to generate whole microservices, you can specify filterMethod and filterArray
+4. run the command where you should pass your login and pass from saddleback identity server `saddlebackApi --config openapiEvents.config.json --login login --password password`
+### local swagger
+1. same as above
+2. same as above
+3. addition specify the input path to the swagger.json file
+4. run the command `saddlebackApi --config openapiEvents.config.json`
