# Literate programming

.pull-left[

- This means we write code in a way that clearly documents 
what we did.

- Instead of writing code with the purpose of telling the 
computer what to do, we write code that tells other humans 
what we told the computer to do and *why*.

- Importantly, we don't separate our code from the report/essay/manuscript
we are writing. Everyting is together, in a single document.

### **Slack**

- Slack is a communication platform we'll use to discuss specific topics outside 
of class.

- It also serves as a resource for students to ask questions and exchange 
information relevant to the course.

- You will receive an email with an invitation link to join the course Slack ([www.ru-span420.slack.com](http://www.ru-datasci4ling.slack.com))

- For personal matters (only) you can email the professor.
