How to document the API

/**
 * This function comment is parsed by doctrine
 * @route GET /api
 * @group foo - Operations about user
 * @param {string} email.query.required - username or email - eg: user@domain
 * @param {string} password.query.required - user's password.
 * @returns {object} 200 - An array of user info
 * @returns {Error}  default - Unexpected error
 */
exports.foo = function() {}

For model definitions:

/**
 * @typedef Product
 * @property {integer} id
 * @property {string} name.required - Some description for product
 * @property {Array.<Point>} Point
 */

/**
 * @typedef Point
 * @property {integer} x.required
 * @property {integer} y.required - Some description for point - eg: 1234
 * @property {string} color
 * @property {enum} status - Status values that need to be considered for filter - eg: available,pending
 */

/**
 * @typedef Error
 * @property {string} code.required
 */

/**
 * @typedef Response
 * @property {[integer]} code
 */
