-$ git clone git@github.com:bridge5/node-examination.git
-$ cd node-examination/swagger
-$ npm start
-
-$ open http://localhost:3030/docs 
-```
-
-## Tasks
-
-1. Please read the swagger documentation and implement these features under app folder.
-2. Please add tests using your preferred testing tool (chai, mocha, Jasmine ...).
-3. Please add some features that could help you show your personal abilities.
-
-## Objectives
-
-- Please check for small things like syntax errors, since details matter.
-- Please deliver something that works, non working project is an automatic disqualification.

-# Swagger Codegen Ignore
-# Generated by swagger-codegen https://github.com/swagger-api/swagger-codegen
-
-# Use this file to prevent files from being overwritten by the generator.
-# The patterns follow closely to .gitignore or .dockerignore.
-
-# As an example, the C# client generator defines ApiClient.cs.
-# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
-#ApiClient.cs
-
-# You can match any string of characters against a directory, file or extension with a single asterisk (*):
-#foo/*/qux
-# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
-
-# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
-#foo/**/qux
-# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
-
-# You can also negate patterns with an exclamation (!).
-# For example, you can ignore all files in a docs folder with the file extension .md:
-#docs/*.md
-# Then explicitly reverse the ignore rule for a single file:
-#!docs/README.md
