This is an easy version that starts with canned beef broth. Some of the ingredients may be hard for people in some parts of the world to find--I live in an area with a large Asian population so I've never had any trouble myself. Be careful when using the sriracha or sambal oelek, as they are very hot. Fish sauce, to the uninitiated, smells really awful--but it doesn't taste like it smells. Once you've added it to your soup, you won't smell it nearly so strongly and it adds a pleasant, salty, seafood-y flavor to your food.
