How to Use Custom Plugins in Wordpress Themes

1. Log in to your Wordpress site. Open up your FTP program. Upload your custom plugin files to the folder 'plugins' folder under 'wp-content.'
2. Close your FTP program ,then click 'Plugins,' then the sub-menu item 'Plugins.'

3. Click 'Activate' on your custom plugin.
4. Click 'Appearance' and 'Themes' if you need to add any code tags to your theme to make your custom plugin work. The exact theme file that you need to edit for your plugin depends on the type of plugin, although typically you'll add it to the home, sidebar or single post pages. Save your changes once you have completed them.
