 We created these videos as an intro to educate the team on our product. The goal is for them to be consumable and understood by a non-technical audience. If you have any feedback on how to improve these, feel free to send it directly to the Slack channel #wg-product-onboarding. More to come here as we continue to create more internal training tools to help every Sourcegrapher understand the power of our product!
