When doing community service for XYZ sorority, what should your letter include? - letter of community service recommendation

If I am currently active in the community and have established a good relationship. Where I feel comfortable to call for a letter of recommendation. What should be included in the letter? For example, specify, whether the person who wrote the letter, as long as I am a volunteer and the exact time? (1 year or 500 hours) or in the form of a letter indicating the kind of person am I? When you are asked what is the recommendation that, I must say that it is possible to join a guild? You must include in the letter, why is an enrichment for the guild. Or should it just how focused I volunteer? If the organization that I am is volunteering on the ground makes a bad image because it is not known at the national level? Or does not matter as long as I Serving. Last question, if I know someone who just started his own mentoring program and volunteers who do not volunteer as trustworthy?
