This document discusses the use of transitions in writing. It explains that transitions signal relationships between ideas and guide readers from one part of a document to another. Various transition words and phrases are presented that can link sentences and paragraphs together. Major transitions between sections should summarize the previous section, refer back to the thesis, and preview the next section. The document also discusses using an "old/new contract" where the beginning of sentences reference old information from earlier in the text and the end of sentences introduce new information.
