# ✅Requirements

## Java Version

* Basic Requirement: **Java16+**
* **Java 17+** is <mark style="color:red;">recommended</mark>. Java17 and above versions are recommended, but plugins are compiled using **Java16**, so theoretically, you only need Java16 or higher versions.

## Server Software

* **Paper** and its downstream forks are <mark style="color:red;">recommended</mark>. When the plugin detects that your server software is Paper, it will enable some features that are only available in Paper, some of which can provide subtle performance improvements.
* **Folia** server also supported. Please note: Folia's support is in the <mark style="color:red;">early testing stage</mark> and may be released in official versions or removed in the future. This support is not a guarantee.

## Server Version

| Version              | Can work in your server                                                                                                   | Can get offical support |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------- | ----------------------- |
| **Below 1.14**       | ❌                                                                                                                         | ❌                       |
| **1.14 \~ 1.20.4**   | <p>❓<br>The plugin can run on these versions, however, any issues caused on these versions will not be resolved.</p>      | ❌                       |
| **1.20.5 and above** | <p>✅<br>Using versions <strong>1.21.5</strong> and above is the most recommended, as you can enjoy the best features.</p> | ✅                       |

* If you encounter errors while using a certain version, <mark style="color:red;">please join our Discord feedback</mark>.

## An economy plugin if you want to use custom currency

* **UltimateShop** is just a shop plugin and does not provide custom economy functionality. If you need a custom economy as your server economy, please find a suitable economy plugin yourself. **Vault** is not an economy plugin, it is just a dependency plugin for many economy plugins. <mark style="color:red;">After installing Vault on the server, it is also necessary to install the economy plugins that support it</mark>.
