 The server hosts the platform interface to contestants along with all units related to solution testing (test cases, checker, validator, interactor, etc). When the server accepts a solution from a user, it forwards this solution along with testing units (which could be cached) to a volunteer. The client performs the testing protocol and reports the results back to the server, which in turn reports the result back to the contestant. All communication channels (contestant-server, server-volunteer) are to be implemented on top of HTTPS.

+### Server
+
+#### Setup
+
+##### Run locally
+
+To get this project up and running locally on your computer:
+
+1. Set up a [Nodejs](https://wiki.developer.mozilla.org/en-US/docs/Learn/Server-side/Express_Nodejs/development_environment) development environment.
+1. Once you have node setup, enter the following commands in the root of your clone of this repo:
+   ```
+   #Go to server directory
+   cd server
+
+   #Install dependencies
+   npm install
+
+   #Start development server 
+   DEBUG=distributed-online-judge:* npm run devstart
+   ```
+1. Open a browser to http://localhost:3000/ to open the site.
+
+> **Note:** The library uses a default MongoDb database hosted on [MongoDB Atlas](https://www.mongodb.com/cloud/atlas). You should use a different database for your own code experiments.
+
+##### Run on Docker
+
+1. Make sure Docker and Docker Compose installed
+1. Enter the following commands in the root of your clone of this repo:
+   ```
+   #Go to server directory
+   cd server
+
+   #Run docker compose
+   docker-compose up
+   ```
+1. Open a browser to http://localhost/ to open the site.
+
+#### APIs
+
+Once you have the server run on your machine (locally or using Docker), APIs are documented under `/api-docs/` path using `Swagger`.
+

+| HTML Verb | URL | Description |
+|-----------|-----|-------------|
+| GET | /ui/problems | Display all available problems |
+| GET | /ui/problems/create | Show form to make new problem |
+| POST | /ui/problems/create | Add new problem to database and redirect |
+| GET | /ui/problems/:id | Show info about one problem |
+| GET | /ui/solutions | Display all available solutions |
+| GET | /ui/solutions/create | Show form to make new solution |
