Select "File Manager."
Click on "Add source" and then select "None."
Enter the following URL: http://tempest.zapto.org/repo/ and click "OK."
Name the source "Tempest" and click "OK."
Go back to the home screen and select "Add-ons."
Click on the "Package Installer" icon (it looks like a box) in the top-left corner of the screen.
Select "Install from zip file."
Click on "Tempest" and select the repository file: "repository.tempest-x.x.x.zip" (where "x.x.x" is the version number).
Wait for the installation notification to appear.
Select "Install from repository."
Click on "Tempest Repo" and select "Video add-ons."
Select "Tempest" and then click "Install."
Wait for the installation notification to appear.
The Tempest add-on is now installed on Kodi and you can access it from the "Add-ons" section of the home screen. It's important to note that Kodi add-ons can sometimes be taken down or removed, so the above steps may not work in the future. Additionally, it's important to ensure that you are using Kodi in accordance with local laws and regulations, and to be mindful of copyright infringement.
