Sources for brazilian jiu-jitsu

Every number in the text, like 3, points here. The pages are written in our own words from these sources. Where sources disagree, the pages say so and show each version. Rules and grades are each body's own, with the date we read them, and change over time.

How these pages were made

Researched and drafted with computer help, checked against the sources below, and read by a karate instructor. Pictures are drawn, with computer help, under our direction, and none shows a real child. Recorded chapters and words are read by a computer voice; a word not yet recorded uses your device's own voice. If you spot a mistake, email hello@everydojo.com.
