Check what version of Node you're running.

node --version

If it doesn't start with v4 or greater (v5, etc.), you need to update Node. You're probably on a Mac and installed Node via Homebrew, so try:

brew update
brew upgrade node

Inside the bean-docs folder, run this to install the project dependencies:

npm install

npm run build   # build the site into /build
npm run serve   # serve the site at localhost:8080 with live reloading
npm run deploy  # deploy to GitHub Pages

Images go inside src/_assets/images/FOLDER_NAME/FILE_NAME/IMAGE_NAME.EXT, where FOLDER_NAME and FILE_NAME match the document referring to them.

Here's where you would put an image named blue_led.jpg to be accessed from inside the features/accelerometer.md guide:

src/_assets/images/features/accelerometer/blue_led.jpg

Inside accelerometer.md, add the following Handlebars helper call to add the image tag:

{{{img_rel this 'blue_led.jpg' 'A description of this image'}}}

When you use the above tag in your own documents, replace blue_led.jpg with your actual file name, and replace "A description of this image" with your own description of your image.

To make an image take up less width horizontally and place margins around the left and right sides, add a max width argument:

{{{img_rel this 'blue_led.jpg' 'A description of this image' '50%'}}}

The image above will be 50% the width of the content column with 25% margins on the left and right sides.

For videos, use the same syntax with video_rel instead:

{{{video_rel this 'move_bean.mp4' '60%' true}}}

'video_rel' takes an additional argument for enabling autoplay and looping.

Note: The max width argument doesn't work with videos yet.

We have a few checks for both code and content. Rum them as follows:

npm run lint-style  # Check Markdown files for common writing errors
npm run lint-code   # Check JavaScript files for style errors
