 The goal of DAO voting system is to gather the thoughts and will of the Threefold community and build projects that are aligned with the ethos of the project.
 
 We encourage anyone to share their ideas. Who knows? Your sudden spark of genius might lead to an accepted proposal on the Threefold DAO!

+## Voting Weight
+
+The DAO votes are weighted as follows:
+
+- Get all linked farms to the account
+- Get all nodes per farm
+- Get compute and storage units per node (CU and SU)
+- Compute the weight of a farm:
+  ```
+  2 * (sum of CU of all nodes) + (sum of SU of all nodes)
+  ```
+
+Voting weights are tracked per farm to keep it easy and traceable. Thus, if an account has multiple farms, the vote will be registered per farm.

+
+## Introduction
+
+We show how to deploy a Kubernetes cluster and set a [MinIO](https://min.io/) Operator with [Helm 3](https://helm.sh/).
+
+MinIO is a high-performance, S3 compatible object store. It is built for
+large scale AI/ML, data lake and database workloads. Helm is a package manager for Kubernetes that allows developers and operators to more easily package, configure, and deploy applications and services onto Kubernetes clusters.
+
+## Prerequisites
+
+- TFChain account with TFT
+- [Deploy Kubernetes cluster with one master and one worker (IPv4)](../../dashboard/solutions/k8s.md)
+- [Make sure you can connect via SSH on the terminal](../../system_administrators/getstarted/ssh_guide/ssh_openssh.md)
+  
+## Create an SSH Tunnel
+
+To access the MinIO Operator, we need to create an SSH tunnel with the port 9090.
+
+- Open a terminal and create an SSH tunnel
+    ```
+    ssh -4 -L 9090:127.0.0.1:9090 root@<VM_IP>
+    ```
+
+Simply leave this window open and follow the next steps.
+
+## Set the VM
+
+We set the Master VM to access the minIO Operator.
+
+- Install the prerequisites:
+    ```
+    apt update
+    apt install git -y
+    apt install wget
+    apt install jq -y
+    ```
+- Install Helm
+    ```
+    wget https://get.helm.sh/helm-v3.14.3-linux-amd64.tar.gz
+    tar -xvf helm-v3.14.3-linux-amd64.tar.gz
+    mv linux-amd64/helm /usr/local/bin/helm
+    ```
+- Install yq
+    ```
+    wget https://github.com/mikefarah/yq/releases/download/v4.43.1/yq_linux_amd64.tar.gz
+    tar -xvf yq_linux_amd64.tar.gz
+    mv yq_linux_amd64 /usr/bin/yq
+    ```
+
+## Set MinIO
+
+We can then set the MinIO Operator. For this step, we mainly follow the MinIO documentation [here](https://min.io/docs/minio/kubernetes/upstream/operations/install-deploy-manage/deploy-operator-helm.html).
+
+- Add the MinIO repo
+    ```
+    helm repo add minio-operator https://operator.min.io
+    ```
+- Validate the MinIO repo content
+    ```
+    helm search repo minio-operator
+    ```
+- Install the operator
+    ```
+    helm install \
+    --namespace minio-operator \
+    --create-namespace \
+    operator minio-operator/operator
+    ```
+- Verify the operator installation
+    ```
+    kubectl get all -n minio-operator
+    ```
+
+## Access the MinIO Operator
+
+You can then access the MinIO Operator on your local browser (port 9090)
+
+```
+localhost:9090
+```
+
+To log in the MinIO Operator, you will need to enter the token. To see the token, run the following line:
+
+```
+kubectl get secret/console-sa-secret -n minio-operator -o json | jq -r ".data.token" | base64 -d
+```
+
+Enter the token on the login page:
+
+![minio_1](./img/minio_1.png)
+
+You then have access to the MinIO Operator:
+
+![minio_2](./img/minio_2.png)
+
+
+## Questions and Feedback
+
+If you have any questions, feel free to ask for help on the [ThreeFold Forum](https://forum.threefold.io/).
