+#### Formatting the description literals: ####
+Swagger supports the Markdown syntax to format strings. This can be especially handy if you were to provide a long description of a given API version or endpoint. Use [this guide](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet) for reference.
+
+__NOTE:__ There is one difference between the official Markdown syntax and Swagger interpretation, namely tables. To create a table like this:
+
+| Column1 | Collumn2 |
+| ------- | -------- |
+| cell1   | cell2    |
+
+you should use the folowing syntax, making sure there are no whitespaces at the start of any of the lines:

+| ------- | -------- |&#13;
+| cell1   | cell2    |&#13;

+```
+
 ### Specifying/Testing API Security ###
 
 Swagger allows for the specification of different security schemes and their applicability to operations in an API. To leverage this in rswag, you define the schemes globally in _swagger_helper.rb_ and then use the "security" attribute at the operation level to specify which schemes, if any, are applicable to that operation. Swagger supports :basic, :apiKey and :oauth2 scheme types. See [the spec](http://swagger.io/specification/#security-definitions-object-109) for more info.

 Rswag ships with an embedded version of the [swagger-ui](https://github.com/swagger-api/swagger-ui), which is a static collection of JavaScript and CSS files. These assets are served by the rswag-ui middleware. However, for optimal performance you may want to serve them directly from your web server (e.g. Apache or NGINX). To do this, you'll need to copy them to the web server root. This is the "public" folder in a typical Rails application.
