 Download CodeChain code
 
-```
+```sh
 git clone git@github.com:CodeChain-io/codechain.git
 cd codechain
 ```
 
 Build in release mode
 
-```
+```sh
 cargo build --release
 ```
 
 This will produce an executable in the `./target/release` directory.
 
+##Setup
+
+###Using Docker
+
+CodeChain supports the use of Docker to provide an easy and seamless installation process by providing a single package that gives the user everything he/she
+needs to get CodeChain up and running. In order to get the installation package, run the following command after installing Docker:
+
+```sh
+docker build -f docker/ubuntu/Dockerfile --tag codechain-io/codechain:branch_or_tag_name .
+```    
+
+WSL users may find difficulty in using Docker, and thus, it is highly recommended to use Ubuntu, or install Docker for Windows. When using Docker for Windows,
+it is necessary to enable Hyper-V in BIOS settings.
+
+To see the Docker images created, run the following:
+```sh
+docker images
+```
+
+It will result in something like this:
+```sh
+REPOSITORY               TAG                  IMAGE ID            CREATED              SIZE
+codechain-io/codechain   branch_or_tag_name   6f8474d9bc7a        About a minute ago   1.85GB
+ubuntu                   14.04                971bb384a50a        6 days ago           188MB
+```
+    
+If you want to run the first image file, run the following command:
+```sh
+docker run -it codechain-io/codechain:branch_or_tag_name
+```
+
+This should result in CodeChain running.
+
+###Building From Source
+
+####Build Dependencies
+CodeChain requires Rust version 1.32.0 to build. Using [rustup](https://rustup.rs/ "rustup URL") is recommended.
+
+- For Linux Systems:
+  - Ubuntu
+
+    > `gcc`, `g++` and `make` are required for installing packages.
+    ```sh
+    $ curl https://sh.rustup.rs -sSf | sh
+    ```
+        
+
+- For Mac Systems:
+  - MacOS 10.13.2 (17C88) tested
+    > `clang` is required for installing packages.
+
+    ```sh
+    $ curl https://sh.rustup.rs -sSf | sh
+    ```
+        
+
+- For Windows Systems:
+  - Currently not supported for Windows. If on a Windows system, please install [WSL](https://docs.microsoft.com/en-us/windows/wsl/install-win10) to continue as Ubuntu.
+
+Please make sure that all of the binaries above are included in your `PATH`. These conditions must be fulfilled before building CodeChain from source.
+
+
+Download CodeChain's source code and go into its directory.
+```sh
+git clone git@github.com:CodeChain-io/codechain.git
+cd codechain
+```
+
+####Build as Release Version
+```sh
+cargo build --release
+```
+
+This will produce an executable in the ./target/release directory.
+
+###Using CodeChain SDK
+
+Before starting to use the CodeChain SDK, please install node.js by going to this [page](https://nodejs.org/en/).
+
+Next, install the package with the following command:
+
+`npm install codechain-sdk` or `yarn add codechain-sdk`
+
