9.1. Lesson: Installing and Managing Plugins¶
To begin using plugins, you need to know how to download, install and activate them. To do this, you will learn how to use the Plugin Installer and Plugin Manager.
The goal for this lesson: To understand and use QGIS‘ plugin system.
9.1.1. Follow Along: Managing Plugins¶
To open the Plugin Manager, click on the menu item .
In the dialog that opens, find the Processing plugin:
Click in the box next to this plugin and uncheck it to deactivate it.
Looking at the menu, you will notice that the Processing menu is is now gone. This means that many of the processing functions you have been using before have disappeared!

Open the Plugin Manager again and reactivate the Processing plugin by clicking in the checkbox next to it.
Close the dialog. The Processing menu and functions should be available again.
9.1.2. Follow Along: Installing New Plugins¶
The list of plugins that you can activate and deactivate draws from the plugins that you currently have installed. To install new plugins:
Select the Not Installed option in the Plugin Manager dialog. The plugins available for you to install will be listed here. This list will vary depending on your existing system setup.
Find information about the plugin by selecting it in the list
Install the one(s) you are interested in by clicking the Install Plugin button below the plugin information panel.
if the plugin has some error it will be listed in the Invalid tab. You can then contact the plugin owner to fix the problem.
9.1.3. Follow Along: Configuring Additional Plugin Repositories¶
The plugins that are available to you for installation depend on which plugin repositories you are configured to use.
QGIS plugins are stored online in repositories. By default, only the official repository is active, meaning that you can only access plugins that are published there. Given the diversity of available tools, this repository should meet most of your needs.
It is possible, however, to try out more plugins than the default ones. First, you want to configure additional repositories. To do this:
Open the Settings tab in the Plugin Manager dialog
Click Add to find and add a new repository.
Provide a Name and URL for the new repository you want to configure and make sure the Enabled checkbox is selected.
You will now see the new plugin repo listed in the list of configured Plugin Repositories
You can also select the option to display Experimental Plugins by selecting the Show also experimental plugins checkbox.
If you now switch back to the Not Installed tab, you will see that additional plugins are available for installation.
To install a plugin, click on it in the list and then on the Install plugin button.

Installing plugins in QGIS should be straightforward and effective!
