Project layout

The Ember Guides content is written in Markdown. Each minor version of Ember has its own directory within


In general, your PR should make edits to only the files in the

directory, which corresponds to the latest version of Ember. Exceptions may include fixing broken links and typos in older versions of the Ember Guides.

If you run

ember serve
, the Markdown files are turned into HTML to create an app. We use the following addons to make this happen:

Local development

NOTE: This project uses Volta to ensure the correct Node.js and NPM version is used during local development.

To run the Ember Guides app locally, type these commands into your terminal.

git clone git://

cd guides-source npm install ember serve

Afterwards, visit http://localhost:4200 in your browser.

Note: On Mac, if you get the error

Error: EMFILE: too many open files, watch
, try installing Watchman. Install Homebrew if you don't have it. Then, in your terminal, run
brew install watchman

Running tests


npm test
to run tests locally. In addition to the Ember app, we check for broken links.
npm test

Linting and spellchecking

The guides are spellchecked and linted for Markdown consistency. You can check your edits by running,

npm run lint:md

Linting and spellchecking must pass or they will fail in CI (continuous integration). See for more information on linting and spellchecking.

Internal and external links

Testing of internal and external links can be performed using three commands:

# Run all test scripts in `/node-tests` except those located
# in `/node-tests/local`. In particular, this command checks
# all internal links across all versions of the Guides.
npm run test:node

Run all test scripts in /node-tests/local. In particular,

this command checks all external links in the release version

of the Guides.

npm run test:node-local

When checking external links in the release version, don't

check links to the API docs (

npm run test:node-local-exclude-api-urls
