This page will show you how to install the Wolvenkit Blender Plugin from a github release or tag. If you want to install the bleeding edge, please check Installing from github source instead.
Navigate there with your Windows Explorer (Hotkey: Windows+R, paste the path above after changing your Blender version), and delete everything — either the entire folder, or all files inside.
Optional: Close and re-open Blender
Step 0: Download the plugin
If you want to install the current development version of the plugin, read Installing from github source (NOT for beginners)
Download the latest release of the plugin from github:
On the releases page, find the most recent release
Scroll past the change notes to the Assets section
Download the zip file with the plugin:
Do not download anything called "Source code", unless you know what you're doing
Step 1: Install the plugin
Start Blender
Open the Blender Preferences (Toolbar: Edit -> Preferences) and select the AddOns tab
Click the "Install" button and select the zip file you downloaded in step 2
Step 2: Enable the plugin
You only need to do this if you never installed the plugin before.

Make sure the box is checked and restart Blender.
Troubleshooting
I can't (un)install the plugin!
You can do both by hand. Find your Blender install's plugin folder, the path will look something like this (replace 3.6 with your Blender version):
Inside the plugins folder, the Wolvenkit Blender IO Suite will be installed to the subfolder i_scene_cp77_gltf.
To uninstall the plugin, delete the entire folder.
To install the plugin, find the folder in your downloaded zip file that contains the file __init__.py, move it here, and rename it.
