Things to Know Before Installing WordPress
 Before you begin the install, there are few things you need to have and do.

You need access to your site and its directory and software to proceed with the installation. These are:

• An access to your web server (via shell or FTP)
• A text editor
• An FTP Client (if you need to install WordPress on a remote server)
• Your web browser of choice

Things You Need to Do to Install WordPress
 Begin your installation by:

1. Checking to ensure that you and your web host have the minimum requirements to run WordPress.
2. Download the latest release of WordPress.
3. Unzip the downloaded file to a folder on your hard drive.
4. Be prepared with a secure password for your Secret Key
5. Print this page out so you have it handy during the installation.

Famous 5-Minute Install
 Here's the quick version of the instructions, for those that are already comfortable with performing such installations.
More detailed instructions follow.

1. Download and unzip the WordPress package, if you haven't already.
2. Create a database for WordPress on your web server, as well as a MySQL user who has all privileges for accessing and modifying it.
3. Rename the wp-config-sample.php file to wp-config.php.
4. Open wp-config.php in your favorite text editor and fill in your database details as explained in Editing wp-config.php to generate and use your secret key password.
5. Place the WordPress files in the desired location on your web server:
   • If you want to integrate WordPress into the root of your domain (e.g. http://example.com/), move or upload all contents of the unzipped WordPress directory (but excluding the directory itself) into the root directory of your web server.
   • If you want to have your WordPress installation in its own subdirectory on your web site (e.g. http://example.com/blog/), rename the directory wordpress to the name you'd like the subdirectory to have and move or upload it to your web server. For example if you want the WordPress installation in a subdirectory called "blog", you should rename the directory called "wordpress" to "blog" and upload it to the root directory of your web server.

6. Run the WordPress installation script by accessing wp-admin/install.php in your favorite web browser.
   • If you installed WordPress in the root directory, you should visit: http://example.com/wp-admin/install.php
   • If you installed WordPress in its own subdirectory called blog, for example, you should visit: http://example.com/blog/wp-admin/install.php

That's it! WordPress should now be installed.
