-To silence the fans, install `ipmitool`
+## Quick start
+1. Install dependencies
 ```bash
-apt install ipmitool -y
-```
-
-Enable manual fan control
-```bash
-ipmitool raw 0x30 0x30 0x01 0x00
-```
-
-Disable manual fan control
-```bash
-ipmitool raw 0x30 0x30 0x01 0x01
-```
-
-Turn fan to 10% - 0xA is 10
-```bash
-ipmitool raw 0x30 0x30 0x02 0xff 0xA
-```
-
-Turn fan to 20% - 0x19 is 20
-```bash

-## Tailscale VPN
-Setup tailscale to access network externally
-
-### Proxmox access
-1. [Install tailscale client on access devices](https://tailscale.com/download)
-2. [Install tailscale on target device](https://tailscale.com/kb/1031/install-linux)
+2. Provide env variables:
+  - `terraform login`
+  - Create `terraform/terraform.tfvars` according the `terraform/variables.tf`
+3. Deploy
 ```bash
-curl -fsSL https://tailscale.com/install.sh | sh
+pnpm dep
 ```
-3. Access target device by enabling tailscale VPN and access via assigned IPv4 or IPv6
 
-### LXC access
-Instructions taken from https://dustri.org/b/running-tailscale-inside-of-a-proxmox-container.html
+## Layout
+Folder structure:
+- `docs` - helpful commands
+- `kubernetes` - all the kubernetes related configs
+- `terraform` - config for deploying infra on proxmox
 
-1. Add some lxc config in proxmox specifying correct ID  - 100 in this example
-```bash
-echo 'lxc.cgroup.devices.allow: c 10:200 rwm' >> /etc/pve/lxc/100.conf
-echo 'lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file' >> /etc/pve/lxc/100.conf
-```
-2. Enter lxc container
-```bash
-pct enter 100
-```
-3. Install and configure tailscale
-```bash
-curl -fsSL https://tailscale.com/install.sh | sh
-echo 'net.ipv4.ip_forward = 1' | tee -a /etc/sysctl.conf
-echo 'net.ipv6.conf.all.forwarding = 1' | tee -a /etc/sysctl.conf
-sysctl -p /etc/sysctl.conf
-reboot
-```
