+## Introduction
+
+We show how to deploy a Minetest server on the TFGrid, install Minetest on a local machine and access the Minetest server from the local machine.
+

+
+## Prerequisites
+
+- [A TFChain account](dashboard@@wallet_connector)
+- TFT in your TFChain account
+  - [Buy TFT](threefold_token@@buy_sell_tft)
+  - [Send TFT to TFChain](threefold_token@@tft_bridges)
+
+## Deploy a Full VM
+
+We start by deploying a full VM on the ThreeFold Dashboard.
+
+* On the [Threefold Dashboard](https://dashboard.grid.tf/#/), go to the [full virtual machine deployment page](https://dashboard.grid.tf/#/deploy/virtual-machines/full-virtual-machine/)
+* Deploy a full VM (Ubuntu 22.04) with an IPv4 address and at least the minimum specs for a full VM
+  * Network
+    * Set IPv4 Address (required)
+    * Set Wireguard (optional)
+  * Minimum vcores: 1vcore
+  * Minimum MB of RAM: 512MB
+  * Minimum storage: 15GB
+* After deployment, note the VM IPv4 address
+* SSH into the VM
+    ```
+    ssh root@vm_ipv4_address
+    ```
+
+
+## DNS Settings
+
+You need to set an A record for the IPv4 address.
+
+The following table explicitly shows how to set the A record for your domain. Note that we set `minetest` as a subdomain.
+
+| Type | Host | Value          |
+| ---- | ---- | -------------- |
+| A    | minetest   | <ipv4_address> |
+
+
+You will then be able to access your server on Minetest with the URL `minetest.example.com:30033`. More on the port below.
+
+### DNS Verification
+
+You can use tools such as [DNSChecker](https://dnschecker.org/) or [dig](https://linux.die.net/man/1/dig) on a terminal to check if the DNS propagadation is complete.
+
+
+- Check that the subdomain resolves to the IPv4 address of the full VM
+    ```
+    minetest.example.com
+    ```
+
+## Run a Minetest Server on the TFGrid
+
+
+- Install the Minetest server
+```
+apt update
+apt install minetest-server -y
+```
+- Set the Minetest server
+```
+nano /etc/minetest/minetest.conf
+```
+- Update the following lines
+```
+server_name = Server Name
+
+server_address = http://minetest.example.com
+
+server_announce = true
+
+port = 30033
+```
+- Run the Minetest server
+```
+minetestserver --worldname world
+```
+
+## Run Minetest Locally
+
+- Update the local machine
+```
+apt update
+```
+- Install Minetest
+```
+apt install flatpak -y
+apt install gnome-software-plugin-flatpak -y
+flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
+```
+- Reboot the machine 
+- Install Minetest
+```
+flatpak install flathub net.minetest.Minetest
+```
+- Run Minetest
+```
+flatpak run net.minetest.Minetest
+```
+
+## Access the Server from Minetest
+
+- On Minetest, go to the server you previously set
+
+![](./img/minetest_2.png)
+
+- You can then access the Minetest world!

+
+## Public Server Notes
+
+Once you set the Minetest server publicly, you can see it displayed on https://servers.minetest.net/.
