The Opendelight is easy to use for your PHP application development and offers an easy learning curve to build and manage your apps, in a matter of minutes. On this page, you will find a few easy steps to start using the Opendelight.

#### Minimum Requirements

PHP5 with PHP Data Object (PDO) enabled, with any relational database that is supported by PDO. For more details about PDO, please refer to the official documentation.

Download the latest stable release of the Opendelight in the ZIP file from the website.

#### Installation

Installing Opendelight is quite easy and fast. Please follow the instructions below to install the Opendelight - a task of a few minutes.

Download the Opendelight ZIP from the Download page and unzip it into any folder or subfolder in your webroot ("webroot" is the parent folder or directory in your PC or server which can be accessed through HTTP).

Go to the URL http://your-domain/folder1/folder2/.../folderN/osf/install. Upon doing so, the system will open the Application Setup page as shown below.

Click on the Click to begin Setup button as shown above. Upon doing so you will be taken to a page to fill in the details of your application as shown below. Fill in the requisite details and click the Submit button.

Upon doing so the system will install the application for you and you will land on a success screen with the access details of your application as shown below.

##### NOTE:
1. Check your application URL (where you are going to develop your new application) is correct. If you find any disparity, please rectify it at this point. Make sure that the URL does not have a / at the end.
2. The username admin (case-sensitive) is the superuser who can access the Opendelight IDE and can develop, manage, and access the entire application. This user gets such a right through a default role assigned to it - Administrator. Neither this username nor its association with the role Administrator can be modified.
3. Currently, the Opendelight prescribes the use of PHP Data Object (PDO) as the data-access abstraction layer and prepared statements for querying databases. An example of DSN for MYSQL (by PDO and consequently by the Opendelight) is: MYSQL: mysql:host=yourhostname;dbname=yourdbname
4. The <table_prefix> will be a string that will be prepended to each table in the database. In case of the Opendelight system tables, they will be automatically done. In case of the new tables you create, make sure that you do the same.
5. Once you are done with the development of the application, you can remove the /ide folder on your live site if you wish - this will not affect the working of your live site in any way. You can always upload this folder at any later stage if you would like to modify your application.

Once you install, you are done with your application setup, security procedures, access privilege settings, and sign-in forms. Now, sign in at your Opendelight IDE to start developing your application. You can find all requisite information in the other chapters in this book.
