How do you contribute to open source without code?

My earliest open source contributions date back to the mid-1980s when our organization first connected to UseNet where we discovered the contributed code and the opportunities to share in its development and support. Today there are endless contribution opportunities, from contributing code to making how-to videos. read more Source: https://opensource.com/article/19/4/contribute-without-code
