### Setup your MinIO GitHub Repository

Fork [MinIO upstream](https://github.com/minio/minio/fork) source repository to your own personal repository. Copy the URL of your MinIO fork (you will need it for the `git clone` command below).

```sh
git clone https://github.com/minio/minio
cd minio
go install -v
ls $(go env GOPATH)/bin/minio
```

### Set up git remote as ``upstream``

```sh
$ cd minio

- Kubernetes cluster with `kubectl` configured.

- Acquire TLS certificates, either from a CA or [create self-signed certificates](https://min.io/docs/minio/kubernetes/upstream/operations/network-encryption.html).
