If you have an arm based PC like *Raspberry Pi*, OrangePi, etc and need to use cloudflare warp 1.1.1.1 service, currently there is no warp package for arm arch. Here I'll show how to use warp with unofficial CLI for CLoudflare Warp called **wgcf** and **wireguard** package as open-source VPN tunnel software.

## Download Package
### wgcf
get wgcf here => [https://github.com/ViRb3/wgcf/releases](https://github.com/ViRb3/wgcf/releases)
### wireguard
ubuntu/debian => `apt install wireguard`

## Installation
### Create wgcf profile for wireguard
1. Download **wgcf** and make sure to get the supported architecture. Here I get [wgcf_2.2.15_linux_arm64](https://github.com/ViRb3/wgcf/releases/download/v2.2.15/wgcf_2.2.15_linux_arm64) for my Raspberry Pi 4.
2. Rename the downloaded file with preferred name for easy usage. Here I rename it as *wgcf*. [**optional**]
3. Make it executable with `chmod +x wgcf`
4. Copy it to */usr/local/bin* to make it executable anywhere (global accessible). `cp wgcf /usr/local/bin`
5. Register cloudflare warp account `wgcf register`. The new account will be saved under **wgcf-account.toml**
6. Generate wireguard profile with `wgcf generate`. The WireGuard profile will be saved under **wgcf-profile.conf**.

### Wireguard client setup and connect it
1. Create wireguard directory => `mkdir /etc/wireguard/`
2. `chmod 700 /etc/wireguard/`
3. Copy **wgcf-profile.conf** file to */etc/wireguard* => `cp wgcf-profile.conf /etc/wireguard`
4. Start connection with warp from the client => `wg-quick up wgcf-profile`
5. [**optional**] If you get error `resolvconf: command not found` then you can install openresolv => `apt install openresolv` and then re-run `wg-quick up wgcf-profile`
### Disconnect cloudflare warp
You can disconnect with `wg-quick down wgcf-profile`
### [optional] Checking and Inspect Wireguard
- inspect the wireguard device created => `sudo wg show`
- display the IP address of an outgoing connection. You should see here the IP address of your server => `curl ipinfo.io`
