-## SSH into code-server on VS Code
-
-[![SSH](https://img.shields.io/badge/SSH-363636?style=for-the-badge&logo=GNU+Bash&logoColor=ffffff)](https://ohmyz.sh/) ![Terminal](https://img.shields.io/badge/Terminal-2E2E2E?style=for-the-badge&logo=Windows+Terminal&logoColor=ffffff) [![Visual Studio Code](https://img.shields.io/badge/Visual_Studio_Code-007ACC?style=for-the-badge&logo=Visual+Studio+Code&logoColor=ffffff)](vscode:extension/ms-vscode-remote.remote-ssh)
-
-Follow these steps where code-server is running:
-
-1. Install `openssh-server`, `wget`, and `unzip`.
-
-````bash
-# example for Debian and Ubuntu operating systems
-sudo apt update
-sudo apt install wget unzip openssh-server
-
-2. Start the SSH server and set the password for your user, if you haven't already. If you use [deploy-code-server](https://github.com/cdr/deploy-code-server),
-
-```bash
-sudo service ssh start
-sudo passwd {user} # replace user with your code-server user
-````
-
-### Option 1: cloudflared tunnel
-
-[![Cloudflared](https://img.shields.io/badge/Cloudflared-E4863B?style=for-the-badge&logo=cloudflare&logoColor=ffffff)](https://github.com/cloudflare/cloudflared)
-
-1.  Install [cloudflared](https://github.com/cloudflare/cloudflared#installing-cloudflared) on your local computer
-2.  Then go to `~/.ssh/config` and add the following:
-
-```shell
-Host *.trycloudflare.com
-HostName %h
-User root
-Port 22
-ProxyCommand "cloudflared location" access ssh --hostname %h
-```
-
-3. Run `cloudflared tunnel --url ssh://localhost:22` on the remote server
-
-4. Finally on VS Code or any IDE that supports SSH, run `ssh coder@https://your-link.trycloudflare.com` or `ssh [email protected]`
-
-### Option 2: ngrok tunnel
-
-[![Ngrok](https://img.shields.io/badge/Ngrok-1F1E37?style=for-the-badge&logo=ngrok&logoColor=ffffff)](https://ngrok.com/)
-
-1.  Make a new account for ngrok [here](https://dashboard.ngrok.com/login)
-
-2.  Now, get the ngrok binary with `wget` and unzip it with `unzip`:
-
-```bash
-wget "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip"
-unzip "ngrok-stable-linux-amd64.zip"
-```
-
-5.  Then, go to [dashboard.ngrok.com](https://dashboard.ngrok.com) and go to the `Your Authtoken` section.
-6.  Copy the Authtoken shown there.
-7.  Now, go to the folder where you unzipped ngrok and store the Authtoken from the ngrok Dashboard.
-
-```bash
-./ngrok authtoken YOUR_AUTHTOKEN # replace YOUR_AUTHTOKEN with the ngrok authtoken.
-```
-
-8.  Now, forward port 22, which is the SSH port with this command:
-
-```bash
-./ngrok tcp 22
-```
-
-Now, you get a screen in the terminal like this:
-
-```output
-ngrok by @inconshreveable(Ctrl+C to quit)
-
-Session Status                online
-Account                       {Your name} (Plan: Free)
-Version                       2.3.40
-Region                        United States (us)
-Web Interface                 http://127.0.0.1:4040
-Forwarding                    tcp://0.tcp.ngrok.io:19028 -> localhost:22
-```
-
-Copy the forwarded link `0.tcp.ngrok.io` and remember the port number `19028`. Type this on your local Visual Studio Code:
-
-```bash
-ssh [email protected] -p 19028
-```
-
-The port redirects you to the default SSH port 22, and you can then successfully connect to code-server by entering the password you set for the user.
