+## About Velocity support
+
+**AuthMeReReloaded offers integrated support for Velocity since b46, in order to use, please follow the instructions below.**
+
+
+### Step 1: Enable Velocity hook in config.yml
+
+```yaml
+Hooks:
+    # Do we need to hook with Velocity?
+    velocity: true # Set this to true
+```
+**Then restart your server if you have done so.**
+
+### Step 2: Configure backend server and proxy
+
+**Before we can continue, you need to configure your Velocity proxy forwarding method following [PaperMC's instructions](https://docs.papermc.io/velocity/player-information-forwarding#configuring-modern-forwarding).**
+
+### Step 3: Install AuthMeVelocity on the Proxy
+
+AuthMeVelocity is a plugin that allows Velocity to forward player information to AuthMeReloaded.
+
+**Only install it on the proxy, not on the backend server.**
+
+**You can download it from [Modrinth](https://modrinth.com/plugin/authmevelocity).**
+
+**Then configure follow its instructions.**
