Hello and welcome to this tutorial that will explain how to install a Resource Pack on your server. This pack will be automatically downloaded and installed for players who connect to your server.
1 - Get the ressource pack information
The first step is to download the resource pack of your choice.
- Once you have the resource pack in your possession, go to the website https://minepack.fr/ and drag your resource pack there, then validate.
- The site will give you the necessary information like this:

Copy the content with the Copy button and simply add them to the server.properties file of your server!
2 - Modify the server.properties file of your server
The second step consists of placing the two pieces of information from the first step in the server.properties file of your server. If you don't know how to modify this file, I invite you to follow this tutorial: https://minestrator.com/en/blog/article/manage-server-winscp-filezilla
You need to replace the lines for what you have copied :

Then, restart your server to apply these changes and connect.
You should see a message confirming the download and installation of the Resource Pack.
