feat: Add docker build

This adds a Dockerfile which builds a Docker image
with all required dependencies included.
It helps to simplify installation and usage of the tool.

 * Single file deployment (no external stylesheets)
 * You can now version control and branch your resume.
 
-## Install
+## Installation
+
+### Docker
+
+Run this in the directory where you put your markdown resume:
+
+`docker run -it -v ${PWD}:/resume there4/markdown-resume bash`
+
+In the docker console, you can run `md2resume` on your files.  
+For PDF conversion, run `md2pdf` instead of the usual command.
+
+### Local
+
+1. Clone the repo `git clone git@github.com:there4/markdown-resume.git` or [Download ZIP](https://github.com/there4/markdown-resume/archive/master.zip)
+2. **PHP 7** and **[composer](https://getcomposer.org/download/)** are installed and on your PATH
+3. `composer install` inside of the project directory to install dependencies
+
+4. For generating PDF files, you need to install `wkhtmltopdf`
+    * OSX: `brew cask install wkhtmltopdf` via [Homebrew Cask](https://caskroom.github.io/)
+    * Debian: `sudo apt install php7.0-mbstring wkhtmltopdf`
+    * Fedora `sudo dnf install php-mbstring wkhtmltopdf`
+
+## Usage
+
+The two most important commands are the following two. Run them
+inside the cloned directory
 
-#### OSX
-1. The simplest installation of the PDF to HTML conversion tool is via [Homebrew Cask](https://caskroom.github.io/)
 ```bash
-brew cask install wkhtmltopdf
-```
-2. Download as .zip (cloning has [an issue as of Dec 2017](https://github.com/there4/markdown-resume/issues/65)) and unzip.
-3. [Install PHP 7](https://jason.pureconcepts.net/2016/09/upgrade-php-mac-os-x/) and be sure to update your PATH variable.
-4. [Install 'composer'](https://getcomposer.org/download/), a per-project package installer to setup the rest of the requirements. You may need to run './composer.phar update' to get the correct versions of dependencies.
-5. Now you should be ready to continue down in Quickstart.

-#### Debian
-```bash
-sudo apt install php7.0-mbstring wkhtmltopdf

-    `./bin/md2resume html --template blockish examples/source/sample.md examples/output/`
+./bin/md2resume html --template blockish examples/source/sample.md examples/output/`
+```
 
 If you want to edit your markdown resume in your editor while watching it
 update in your browser, run this command:
-
+```
-    `watch ./bin/md2resume html --refresh yes --template modern examples/source/sample.md examples/output/`
+watch ./bin/md2resume html --refresh yes --template modern examples/source/sample.md examples/output/
+```
 
 This makes the build script run periodically, and html document will refresh
 every two seconds via a meta tag. Open the `./examples/ouput/sample.html` file
 in your browser, and then just save your markdown document when you want to see
 a fresh preview.
