Before you’ll be able to be a developer on Iguana you’re going to need the following accounts set up for you:
A Bitbucket login to get the Mercurial source code
A login to Confluence and Jira which are the systems we use to manage our work in
A login to Slack will be useful since we use this as our messaging system
Have mercurial installed - use home brew to install it. Brew will install the X-code command line tools so you shouldn’t need to install X-code.
