+
+# Step-2 Download release and Extract It (on vm or bm)
+
+Download the latest release from the github repo
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(1).png)

+
+Now hover on the file and `right click` on it select the `copy link address`
+
+Now `goto` the `terminal` where you `ssh` to the server
+
+go to preferred folder where you want to download the release
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(3).png)
+
+Now using `wget` download the release
+
+```bash
+wget https://github.com/REZ-OAN/frp/releases/download/v0.57.0/frp_0.57.0_linux_amd64.tar.gz

+
+# Step-3 Running frp-server  ( on vm or bm)
+
+Now edit the `frps.toml` because we will run the `frp-server` on our `vm` or `bm` 
+
+We need to specify a `port` on our `vm` or `bm` on which the `frp-server`will listen to
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(8).png)
+
+Using `nano` edit the `bindPort` if you want to 
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(9).png)
+
+I have edited the port number
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(10).png)
+
+Now run the server 
+
+```bash
+./frps -c ./frps.toml
+```
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(11).png)
+
+# Step-4 Running our codeserver-python (on local machine)
+
+First need to pull the image from the docker.hub
+
+```bash
+docker pull poridhi/codeserver-python:v1.2
+```
+
+Now, run this and copy the image id to run the image
+
+```bash
+docker images
+```
+
+Run using below command
+
+```bash
+docker run -it -p 5000:8080 b25217878034
+```
+
+Your terminal will look like this

+
+# Step-5 Running frp-client (on our local machine)
+
+Firstly do every thing in done in the **Step-2 ,** after doing all of those things 
+
+Edit the `frpc.toml` 
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(13).png)
+
+Here, `serverAddr` refers to the server from where you locally running service will be **exposed**
+
+And `serverPort` refers to the port where the`frp-server` is listening
+
+And `localPort` refers to the port in which our service is **running**
+
+And `remotePort` refers to the `port`in the `remoteServer` in which our service will be **exposed** to 
+
+Edit the `serverPort` to `4848` and `localPort` to `5000` and set `remotePort` to  `7050` using `nano`
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(14).png)
+
+Now run the `frp-client` 
+
+```bash
+./frpc -c ./frpc.toml
+```
+
+# Step-6 create tunnel on cloudflare and then expose the port
+
+Go to cloudflare dashboard select the `Zero Trust`
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(15).png)
+
+Then open networks drop down and select the tunnels 
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(16).png)
+
+Now click on `create tunnel` 
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(17).png)
+
+Select the recommended connector
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(18).png)
+
+Then click on `next`  and then give a name i choose `test-frp`
+
+Now choose connector environment , i have chosen `docker` 
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(19).png)
+
+Now copy the connector `command` and run it on `detach` mode on your `server` ( in our case 103.174.50.21)
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(20).png)
+
+Now select the domain  and subdomain , and the url server `ip_address:remotePort` 
+
+![Untitled](https://github.com/REZ-OAN/frp/blob/frp-demonstration-with-cloudflare/demonstrated_images/Untitled%20(21).png)
+
+Now hit the URL `test-frp.poridhi.io/?folder=/app/`  will see
