+The Abstractions package consists of black-boxed functions for P2PRC.

+## Functions
+- ```Init(<Project name>)```:  Initializes P2PRC with all the needed configurations. 
+- ```Start()```: Starts p2prc as a server and makes it possible to extend by adding other routes and functionality to P2PRC.

+# NAT Traversal
+P2PRC currently supports TURN for NAT traversal. 
+
+## TURN 
+The current TURN implementation used is FRP. The TURN server is also required when 
+a P2PRC node is acting as a Server. The TURN server is determined based on the Node 
+with the least amount of latency based on the Nodes available on the IPTable. 
+Once a TURN server is determined there are 2 actions performed. The first one is 
+```/FRPPort``` to the TURN server to receive a port which is used to generate the external 
+port from the TURN server. The flow below describes the workflow.
+
+### Client mode
+- Call ```/FRPPort```
+```
+http://<turn server ip>:<server port no>/FRPport
+```
+- Call the TURN server in the following manner. The following is a sample code snippet below. 
+```go
+import (
+    "github.com/Akilan1999/p2p-rendering-computation/p2p/frp"
+)
+
+func main() {
+  serverPort, err := frp.GetFRPServerPort("http://" + <lowestLatencyIpAddress.Ipv4> + ":" + lowestLatencyIpAddress.ServerPort)
+   if err != nil {
+    return nil, err
+   }
+   // Create 1 second delay to allow FRP server to start
+   time.Sleep(1 * time.Second)
+   // Starts FRP as a client with
+   proxyPort, err := frp.StartFRPClientForServer(<lowestLatencyIpAddress.Ipv4>, serverPort, <the port you want to expose externally>)
+   if err != nil {
+     return nil, err
+   }
+}
+```

-# Laplace
 
-Laplace is an open-source project to enable screen sharing directly via browser.
-Made possible using WebRTC for low latency peer-to-peer connections, and WebSocket implemented in golang for WebRTC signaling.
-
-> Demo video: https://youtu.be/E8cUaPrAlzE
-
-[![Laplace for gaming](./doc/laplace-for-gaming.png)](https://youtu.be/E8cUaPrAlzE)
-
-
-## Try Demo
-
-For demo, you can visit https://laplace.madeby.monster/
-
-![Website screenshot](./doc/screenshot-website.png)
-
-
-## Motivation
-
-There are already possible solutions to share your computer screen, e.g. TeamViewer.
-But most of them require installations of software or plugins.
-What Laplace provides is a simple solution to this problem.
-For users wanting to share their screen, all they need to do is to open a website page with their browsers, clicking some buttons, then share some session ID with their peers.
-No installation or registration required.
-
-#### Solving the latency problem
-
-This project also serves as a proof-of-concept (PoC) for screen sharing capability directly in browsers based on WebRTC.
-Using WebRTC, real-time communication is made possible through peer-to-peer connections.
-This proves to be very useful in solving one of the biggest problems is screen streaming: **Latency**. 
-The latency represents how long the delay is from the source to transmit to the remote client.
-If you notice, this latency problem is usually highlighted by game streaming services, since gameplay relies heavily on the interactivity of inputs and outputs.
-
-
-#### Low server cost 
-This solution also solves the server cost problem, since the expensive operations (encoding and transmission) are done on client browsers.
-The server is only needed for serving frontends and for WebRTC signaling.
-
-
-#### Possible Use Cases
-
-- Game streaming from PC to mobile devices.
-- Collaborative work where you need to share your screen with remote coworkers.
-- Mirroring presentation slides and demonstrations.
-
-
-## Installation
-
-Build from source
-
-```bash
-$ git clone https://github.com/adamyordan/laplace.git
-$ cd laplace && go build -o laplace main.go
-$ ./laplace --help
-```
-
-OR, pull the pre-built docker image
-
-```bash
-$ docker pull adamyordan/laplace
-$ docker run adamyordan/laplace ./laplace --help
-```
-
-
-## Program Execution
-
-Executing this project basically serves an HTTP server that will host the frontend and the WebSocket implementation.
-Note that you sometimes need to run HTTPs in order for browser to connect to websocket.
-
-```bash
-$ ./laplace --help
-  -addr string
-        Listen address (default "0.0.0.0:443")
-  -certFile string
-        TLS cert file (default "files/server.crt")
-  -keyFile string
-        TLS key file (default "files/server.key")
-  -tls
-        Use TLS (default true)
-```
-
-By default, you can run the executable without any argument to listen to TLS port 443.
-A self-signed certificate files are provided to ease up development.
-
-```bash
-$ ./laplace
-2020/03/25 01:01:10 Listening on TLS: 0.0.0.0:443
-```
-
-You can then open https://localhost:443/ to view Laplace page.
-You may need to add certificate exceptions. In Chrome, you can type `thisisunsafe`.

-Ubuntu LTS with SSH (Docker)
-=========
-
-A Docker file to build a [docker.io] base container with Ubuntu LTS and a sshd service
-[docker.io]: http://docker.io
-Nice and easy way to get any server up and running using docker
-
-
-Instructions
------------
- - Install Docker first. 
-   Read [installation instructions] (http://docs.docker.io/en/latest/installation/).
- 
- 
- - Clone this repository:
- 
-   `$ git clone https://github.com/art567/docker-ubuntu-sshd.git`
- 
- 
- - Enter local directory:
- 
-   `$ cd docker-ubuntu-sshd`
- 
- - Change passwords in Dockerfile:
- 
-   `$ vi Dockerfile`
- 
- - Build the container:
- 
-   `$ sudo docker build -t art567/ubuntu .`
- 
- 
- - Run the container:
- 
-   `$ sudo docker run -d=true --name=ubuntu --restart=always -p=2222:22 -v=/opt/data:/data art567/ubuntu /start`
- 
- 
- - Your container will start and bind ssh to 2222 port.
- 
- 
- - Find your local IP Address:
- 
-   `$ ifconfig`
- 
- 
- - Connect to the SSH server:
- 
-   `$ ssh root@<ip-address> -p 2222`
- 
- 
- - If you don't want to deal with root:
- 
-   `$ ssh master@<ip-address> -p 2222`
- 
-
-**VERY IMPORTANT!!!**
------------
-
- **Don't forget to change passwords in Dockerfile before building image!**
-
-
-Versions
------------
-Some branches represents Ubuntu versions.
-
-Branch `master` is always represented by latest Ubuntu LTS
-
-   For example:
-   - 12.04 - Ubuntu 12.04 LTS
-   - 14.04 - Ubuntu 14.04 LTS
-   - 16.04 - Ubuntu 16.04 LTS

-Ubuntu LTS with SSH (Docker)
-=========
-
-A Docker file to build a [docker.io] base container with Ubuntu LTS and a sshd service
-[docker.io]: http://docker.io
-Nice and easy way to get any server up and running using docker
-
-
-Instructions
------------
- - Install Docker first. 
-   Read [installation instructions] (http://docs.docker.io/en/latest/installation/).
- 
- 
- - Clone this repository:
- 
-   `$ git clone https://github.com/art567/docker-ubuntu-sshd.git`
- 
- 
- - Enter local directory:
- 
-   `$ cd docker-ubuntu-sshd`
- 
- - Change passwords in Dockerfile:
- 
-   `$ vi Dockerfile`
- 
- - Build the container:
- 
-   `$ sudo docker build -t art567/ubuntu .`
- 
- 
- - Run the container:
- 
-   `$ sudo docker run -d=true --name=ubuntu --restart=always -p=2222:22 -v=/opt/data:/data art567/ubuntu /start`
- 
- 
- - Your container will start and bind ssh to 2222 port.
- 
- 
- - Find your local IP Address:
- 
-   `$ ifconfig`
- 
- 
- - Connect to the SSH server:
- 
-   `$ ssh root@<ip-address> -p 2222`
- 
- 
- - If you don't want to deal with root:
- 
-   `$ ssh master@<ip-address> -p 2222`
- 
-
-**VERY IMPORTANT!!!**
------------
-
- **Don't forget to change passwords in Dockerfile before building image!**
-
-
-Versions
------------
-Some branches represents Ubuntu versions.
-
-Branch `master` is always represented by latest Ubuntu LTS
-
-   For example:
-   - 12.04 - Ubuntu 12.04 LTS
-   - 14.04 - Ubuntu 14.04 LTS
-   - 16.04 - Ubuntu 16.04 LTS
