Logging into the WorkflowMax UI to put times in sucks, so you put it off. If you could enter times at the command line, where you already were, you might actually stay on top of things.

You're going to need to get API keys from WorkflowMax. Believe it or not, you do this by emailing them. They tend to respond reasonably soon. If you have a colleague who already has a set, use theirs; we decide which user to update as based on email address. Once you have your keys, make a file at ~/.wfm.yml containing something to the effect of:

email: me@company.tld
apiKey: 00000000000000000000000000000000
accountKey: 00000000000000000000000000000000

That should be you all set up. Assuming you've got pip installed (your package manager probably has it if you don't, perhaps as python-pip, pip or just as part of python), you can install wfm by running pip install wfm. If it's a system Python install, it may be necessary to install as root with sudo pip install wfm.

Once installed, run wfm and follow the instructions the script gives you.
