GitHub is no stranger to programmers.
It is a free code hosting service for many open source projects.
GitHub uses Git for source code version control. In general, I won’t go into GitHub because it’s only for programmers.
What I want to mention here:
Quite a few WordPress themes/plugins are located here instead of WordPress
So how to install WordPress themes and plugins from GitHub.
You will find the answer in this post.
How to install WordPress themes and plugins from GitHub
Basically installing plugins and themes from GitHub is the same as installing WordPress plugins manually .
First you go to the theme/plugin repository from GitHub. Simply put, you go to the main page of the theme/plugin on GitHub.
For example, I will install the Memcached Is Friend plugin .
As soon as you visit the plugin archive page on GitHub, you click on the Download Zip button.

Now go to WordPress Admin. Go to Plugins -> Add Ne w .
You need to manually upload the plugin from your computer. To do this you need to click on the Upload Plugin button.

Click the Choose File button. Select the zip file of the plugin you just downloaded. Then click on the Install Now button.
WordPress will upload the zip file to your website, extract it, and install the plugin.
Once done, simply click on the Activate Plugin button to activate the plugin.
It’s done.
Update issues for WordPress plugins and themes from GitHub?
By default, WordPress does not show automatic updates for plugins downloaded from GitHub.
Whether you get updates or not depends entirely on the programmer.
They need more code to help you get automatic updates.
In some situations you need to install the GitHub Updater plugin to receive updates.
Now you know how to install WordPress plugins and themes from GitHub.
