 We strongly encourage all non-technical team members to take some kind of entry level programming course - it's part of our 'you're the driver' culture that everyone can at least understand very basic concepts around software development. [Codecademy](https://www.codecademy.com/) is a good place to start and they cover many of the technologies we use, such as Python and React.
 
-The training budget is $1000 per calendar year, but this _isn't_ a hard limit - if you want to spend in excess of this, have a chat with your manager. Where the costs are higher than $1000, please give Charles a heads-up, so he can increase your card limit.

-Time spent talking at conferences and user groups, and time spent coaching others at organizations like [Code Nation](https://codenation.org/), is part of your training. You're not expected to use your own time for this.

-It is expected that you would spend up to half a day a month on these activities. Like the training budget, this isn't a hard limit. If you think you need more than that talk to your manager.
