How to install a Wordpress plugin tutorial

How to install a WordPress Plugin ?

 WordPress offers simple and easy ways of adding Plugins to your blog. From the Administration Panels, click on the Plugin tab. Once you have uploaded a plugin to your WordPress plugin directory, activate it from the Plugins Management page, and sit back and watch your plugin work.
Not all Plugins are so easily installed, but WordPress plugin authors and developers make the process as easy as possible. We've included more detailed information on how to install Plugins below, as well as some things you need to know before you install.

Things to Know Before You Install

There are a few things you need to know before you begin to install WordPress Plugins.
Know before you install. 
Read through the readme.txt files and web pages, as well as any comments regarding the Plugin on an author's website, before you install. The more you know before you install, the easier the process should be.
Plugins require downloading and uploading to install. 
You must be familiar with how to download and upload files and how to use FTP, if required.
Plugins may require modifying WordPress files and templates. 
Familiarity with PHP, HTML, CSS, and CHMOD may be necessary.
Record modifications. 
If you make any changes to the WordPress files or templates, make a note of it in the code by using comments before and after the changes, and in a text file saved to your site and on your desktop to remind you of any additions or modifications to your default files or templates. This will help you repeat these in the future if there are any problems with your site.
Make frequent backups! 
Some Plugins work independently of your blog's content and files, just adding a little something special to the page. Others require modification of content and files, including changes to your database. Before installing any plugin that will make dramatic changes, backup your database and files.
There are several versions of WordPress currently available, and different Plugins available for the different versions. Be sure and read through the information thoroughly to determine if the Plugin will work with your version, or check Plugins/Plugin_Compatibility. If not, consider upgrading.

Installation instructions:

To install a plugin that is not in the plugin browser, the following are the general directions to follow. Be sure and follow the specific instructions provided by the Plugin author. Remember: BACKUP - just in case.
  1. Read through the "readme" file thoroughly that usually accompanies a plugin, or the website article from where you found the plugin. It is often helpful to print out the instructions so you can check off the installation steps as you complete them.
  2. Upload the plugin to the wp-content/plugins folder in your WordPress directory online.
  3. Make any changes to templates or files as required by the Plugin instructions including adding Plugin template tags.
  4. Activate the Plugin:
    1. Access the Plugin Panel in your Administration Panels
    2. Scroll down through the list of Plugins to find the newly installed Plugin (if not visible, start from the beginning to check to see if you followed the instructions properly and uploaded the file correctly).
    3. Click on the Activate link to turn the Plugin on.
  5. Continue making any modifications necessary from the "readme" file instructions to make the plugin's actions meet your needs.
