How the Codecademy FAQ works

Each exercise on Codecademy has a dedicated page for Q&A, all contained within our #faq category.

If you want to ask or answer a question about a particular exercise, simply reply to the topic that corresponds to the exercise you are working on. The easiest way to find the right topic would be to click the “Community Forums” link in the left instructions pane on Codecademy.

Simply scroll down and hit the reply button (reply) to contribute to that exercise’s FAQ. If you have a question unrelated to a particular exercise, please post in #get-help instead and don’t forget to provide a link to what you’re working on so everyone else has context.

Over time, as questions get asked and answered, volunteer super user community members will take everyone’s replies to that thread and split them off into their own page in the “Get Help” category to make everything easier to read. The link to those new threads will then be added to the FAQ list, and the top three of those links are then surfaced directly in the left pane on Codecademy. It’s a virtuous cycle!

By asking and answering questions, you’ll help to build this resource for your fellow learners, so please contribute!
