 ### Responsibility
 
-Since access to the Mailgun API key is required, only members of the @nodejs/build-infra team have the permission to push code to the `master` branch. That was done in order to minimize the posibility of mismatches between the information in this repo, and the actual email routes that are set up.

That was done in order to minimize the possibility of mismatches between the information in this repo, and the actual email routes that are set up.
 
 ### Procedure
 
-The [update](./update) directory contains a node program which will read the aliases mapping file, fetch the list of mail routes from Mailgun and update the routes to make sure they match the required state. The program is run by passing it a domain name as an agument (`update/update.js iojs.org`).

The program is run by passing it a domain name as an argument (`update/update.js iojs.org`).
 
-The Mailgun API key for the given domain is required. It can be found in the `admin_logins.md` file in the secrets repo (build/infra/), or direclty via the Rackspace API. The key should be stored as a file named `iojs.org/credentials.json` in the form: `{ "api-key": "key-abc..." }` within a code tree.

 The programs can be used with `--dry-run` to verify the current status and what will be changed by an update.

+`@nodejs.org` email addresses are managed by the Linux Foundation. In order to set one up:
 * Create an iojs.org alias with associated recipients as described above.
 * Send an email to 'helpdesk@rt.linuxfoundation.org' requesting that the wanted nodejs.org address by directed to the new alias. Please CC an OpenJS Foundation contact person and provide context as to why the alias is needed.
