Changing the default rsa key in Git bash for heroku

	If you're using msysgit with the OpenSSH tools, you need to either create ~/.ssh/id_rsa, or create a git config in ~/.ssh/config which points to your key.

	Here's an example of a Git config for bitbucket that will use the correct username, and a key other than the default key (in case you maintain one key for SSH connections, and another for git accounts).

	Host heroku.com
	Hostname heroku.com
	IdentityFile /C/keys/yourkey.key
	Once in git bash, you can run two commands to add your key to your current session's ssh-agent to avoid having to repeatedly type the key's password.

	eval `ssh-agent`

Dev vs Stage environment vs Prod Environment

	For smaller companies (it's not clear how big yours is), three environments (dev, stage, production) are common. Larger companies will often have a QA environment between dev and stage.

	These normally break down as follows:

	dev: Working code copy. Changes made by developers are deployed here so integration and features can be tested. This environment is rapidly updated and contains the most recent version of the application.

	qa: (Not all companies will have this). Environment for quality assurance; this provides a less frequently changed version of the application which testers can perform checks against. This allows reporting on a common revision so developers know whether particular issues found by testers has already been corrected in the development code.

	staging: This is the release candidate, and this environment is normally a mirror of the production environment. The staging area contains the "next" version of the application and is used for final stress testing and client/manager approvals before
