+# Interactive Videoplayer
+
+This is the repository for the interactive videoplayer used by SEK and ZML. 
+
+## Getting Started
+This project uses [Gulp boilerplate](https://github.com/cferdinandi/gulp-boilerplate). 
+If this boilerplate has not been used before, you have to install the following dependencies first:
+
+### Dependencies 
+*__Note:__ if you've previously installed Gulp globally, run `npm rm --global gulp` to remove it. [Details here.](https://medium.com/gulpjs/gulp-sips-command-line-interface-e53411d4467)*
+
+Make sure these are installed first:
+
+- [Node.js](http://nodejs.org)
+- [Gulp Command Line Utility](http://gulpjs.com) `npm install --global gulp-cli`
+
+### Quick Start
+
+1. In bash/terminal/command line, `cd` into your project directory.
+2. Run `npm install` to install required files and dependencies.
+3. When it's done installing, run one of the task runners to get going:
+	- `gulp` manually compiles files.
+	- `gulp watch` automatically compiles files and applies changes using [BrowserSync](https://browsersync.io/) when you make changes to your source files.
+
+
+## Documentation
+Add your source files to the appropriate `src` subdirectories. Gulp will process and and compile them into `dist`.
+- JavaScript files in the `src/js` directory will be compiled to `dist/js`. 
+    - `main`folder: Contains the code used for the videoplayer.
+    - `vendor`: Contains compressed files of `jQuery` and `Howlerjs`. 
+    -  `audioworker.js` and `videoworker.js` are the web workers for the video- and audioplayer
+- Files in the `src/sass` directory will be compiled to `dist/css`. 
+    - `components` folder: Contains all the different css files. 
+    - `main.scss`: Contains imports for the files in `components`.
+- SVG files placed in the `src/svg` directory will be optimized with SVGO and compiled into `dist/svg`.
+- Files and folders placed in the `copy` directory will be copied as-is into the `dist` directory.
+    - `files`: Contains all external files needed for the videoplayer
+        - `audio`: Contains the audio files.
+        - `video`: Contains the video files in different qualities (HD and SD) and the placeholder image named poster.png.
+        - `config.json`: Is the config file used by the videoplayer to import the video and audio files. 
+    - `fonts`: Contains the font used by this project (open sans).
+    - `index.html`: Main HTML file.
+
+### config.json
+
+The `config.json` file contains the import details used by the videoplayer:
+
+```json
+{
+  "video": {
+    "url-hd": "files/video/hd.mp4",
+    "url-sd": "files/video/sd.mp4"
+  },
+  "audio": {
+    "url-0": "files/audio/a1.mp3",
+    "url-1": "files/audio/a2.mp3",
+    "url-2": "files/audio/a3.mp3"
+  },
+  "streams": 3 
+}
+```
+### Video settings for 3 streams:
+|Quality | Width | Height |
+|:-----------------:|:-------------:|:---------------:|
+| SD | 1280  | 2160 | 
+|HD     | 640          | 1080      |
