Hi Frank, and thanks for contacting CTB.
Let me refer you first to A Model for Getting Started, found under the Help Taking Action graphic. That will give you an overview that will help you determine where to look next. There is a lot of information within CTB, and it can indeed feel overwhelming. Ask yourself specific questions about what you need to know next, and refer to the Table of Contents. That will lead you to relevant chapters and toolkits. Use the Search box to assist you when needed. Also, look for similar efforts under the Connect With Others graphic; knowing about other similar efforts can lead to useful idea exchange.
