+
+## Before creating a pull request
+
+Here small unordered list of guidelines to read before creating a pull request
+- Use java <= 1.8 features
+- Please follow [Google's Java style guide](https://google.github.io/styleguide/javaguide.html)
+- Constants (e.g. the energy cost of an in-game action) should be loaded from config.properties
+- Use `Logmanager.LOGGER` to log messages to the console. Use `.fine()` for debugging messages and `.info()` for 
+info for more important messages 
+that are not too frequently used.
+- Please state what tests have been performed in the pull request

 Program the 8086-like microprocessor of a robot in a grid-based multiplayer world. The game is web based so no installation is required.
 In its current state, players can walk around the game universe and collect Biomass blobs & Iron/copper ore using the online code editor.

+
+# Deploying the server
+
+## Linux
+
+**Installing tools**
+
+On Ubuntu 16.04:
+```bash
+sudo apt install git maven openjdk-8-jdk mongodb
+sudo npm install -g typescript
+```
+
+On Arch:
+``` bash
+sudo pacman -S git maven mongodb jdk8-opendjk
+sudo npm install -g typescript
+
+# Don't forget to start mongodb
+sudo systemctl start mongodb.service
+```
+
+*If needed, visit [troubleshooting mongodb](https://wiki.archlinux.org/index.php/MongoDB#Troubleshooting).*
+
+**Deploying server**
+
+``` bash
+# Obtain source files
+git clone https://github.com/simon987/Much-Assembly-Required.git
+
+# Build
+cd Much-Assembly-Required
+mvn package
+
+# Run
+cd target
+java -jar muchassemblyrequired-*.jar
+```
+
+## Windows (tested on Windows 10)
+
+Installation instructions:
+1. Download the JDK from [here](http://www.oracle.com/technetwork/java/javase/downloads/index.html).
+Install the JDK and update your PATH and JAVA_HOME enviroment variables.
+2. Download Maven from [here](https://maven.apache.org/).
+Install Maven (following the README) and update your PATH enviroment variable.
+3. Download Mongo DB Community from [here](https://www.mongodb.com/download-center#community).
+Install Mongo DB following the instructions [here](https://docs.mongodb.com/manual/tutorial/install-mongodb-on-windows/).
+Update your PATH enviroment variable.
+
+Building instructions:
+```batch
+:: Builds the server
+cd Much-Assembly-Required
+mvn package
+```
+
+Running instructions:
+1. In one Command Prompt window, run Mongo DB:
+```batch
+:: Runs Mongo DB
+mongod
+```
+2. In a second Command Prompt window, run the MAR server:
+```batch
+:: Runs the MAR server
+cd Much-Assembly-Required\target
+java -jar muchassemblyrequired-*.jar
+```
+
+## macOS (tested on Sierra 10.12.6)
+
+**Installation**
+
+1. Install [Maven3](https://maven.apache.org/)
+   -Add Maven bin to your path
+   ```bash
+   export PATH=/path/to/maven/bin.:$PATH
+   ```
+2. Install [MongoDB](https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/?_ga=2.201359831.774868398.1539369140-197602459.1539369140).
+   -Via Brew:
+   ```bash
+   #Update brew
+   brew update
+
+   #Install mongodb
+   brew install mongodb
+
+   #Install latest development release
+   brew install mongodb --devel
+   ```
+   -Via .tar.gz
+   ```bash
+   #Extract files:
+   tar -zxvf mongodb-osx-ssl-x86_64-4.0.3.tgz
+   
+   #Ensure binaries are in your path
+   export PATH=<mongodb-install-directory>/bin:$PATH
+   ```
+If you do not wish to use the default data directory (/data/db), follow the steps for running MongoDB in the install doc.
+
+**Deploying Server**
+
+1. Begin MongoDB service
+   ```bash
+   #If brew:
+   #Launch on login
+   brew services start mongodb
+   #Or, if you don't want/need a background service you can just run:
+   mongod --config /usr/local/etc/mongod.conf
+   
+   #If binary:
+   mongod
+   #Optional, set data directory path:
+   mongod --dbpath <path to data directory>
+   ```
+
+2. Deploy server:
+   ```bash
+   # Obtain source files
+   git clone https://github.com/simon987/Much-Assembly-Required.git
+
+   # Build
+   cd Much-Assembly-Required
+   mvn package
+
+   # Run
+   cd target
+   java -jar muchassemblyrequired-*.jar
+   ```
+
+## Docker
+### Requirements
+
+1. [Docker Compose](https://docs.docker.com/compose/install/#install-compose) (and dependencies)
+
+### Installation
+
+Once Docker and Docker Compose are installed, you can build and start
+this application by running the following command inside this
+application's directory:
+
+`docker-compose up`
+
+Make sure to change `mongo_address` in `config.properties` to `mongodb`.
 
 
-_Building instructions coming soon_
+# Running
+
+Once the server is running, you should be able to connect to `http://localhost:4567` with your browser
