For installation
1) After you download the package, unzip it and upload to the server. 
2) Open the application/config/config.php file with a text editor and set your base URL
3) If you intend to use a database, open the application/config/database.php file with a text editor and set your database settings, ie. server name, user name and password, database name.

As  CodeIgniter follows MVC modles, there are model, view and controller folders

• The Model represents your data structures. Typically your model classes will contain functions that help you retrieve, insert, and update information in your database.
• The View is the information that is being presented to a user.
• The Controller serves as an intermediary between the Model, the View, and any other resources needed to process the HTTP request and generate a web page
