 # Installation
 
 You need ideally the jsonview client library from
 https://github.com/yesmeck/jquery-jsonview/releases. Put the latest release into
 our sites/all/libraries folder so the folder structure looks like the following:
+
+```
 - libraries
---- jsonview
------ dist
-------- jquery.jsonview.css
-------- jquery.jsonview.js
+ \- jsonview
+   \- dist
+     \- jquery.jsonview.css
+     \- jquery.jsonview.js
+```
