+# Registry Console Swagger API 
+
+This is the Swagger-based Registry Console API documentation. The project endpoints documentation in json format can be found in `console-api-swagger.json`, rest of the files in the folder compose Swagger standalone distributive stripped to bare miminum necessary to start the Swagger UI. 
+
+## How to run Swagger to view the endpoints documentation
+
+Since Swagger standalone distributive is nothing but a simple static website it's extremely easy to get it started and view the documentation in a matter of seconds. 
+Note - just a simple opening of `index.html` wouldn't be enough, as with any static website, it'd not be able to handle relative resources requests therefore succesfully render Swagger UI. For this reason it's configured to spin off a simple node.js based http server to serve Swagger UI resources. The following steps required to succesfully start the Swagger UI:
+
+* Install npm dependencies - `npm install`
+* Run - `npm run swagger`
+* Make changes in `console-api-swagger.json`
+    * Upon making changes make sure your browser cache is turned off
+
+
+## How to update the Swagger UI
+
+In order to update Swagger version the following steps should to be taken:
+
+* [Download](https://swagger.io/docs/open-source-tools/swagger-ui/usage/installation/) Swagger standalone distributive
+* Remove `.map.*` files as they are only needed to debug Swagger UI and not to run it
+* Add the link to Console API Swagger documentation file - `console-api-swagger.json` to the `swagger-initializer.js`
+* Copy with replace into the current directory
