In order to install additional plugins for the Textpattern CMS there are several steps you should take.
First you need to log in with the administrative login details for the installation.
Once logged in, navigate to the Admin tab and then click the plugins sub-tab.
You need to copy the complete plugin source code and paste it in the text field, then click Upload. Note that the plugin installation code may be encrypted. This will not be a problem – the installer will properly parse it for you.
On the page that loads you will be provided with the complete plugin code as well as the help available for it. Then you need to click install. The plugin will be automatically added to your application.
Note that once the plugin is installed, you will need to activate it. This can be done by clicking ‘No’ under Active for the plugin. This will change the status to yes and the plugin will be active for your web site.
