+# Chapter Three: Working with Edges
+
+Claims and other credentials offer crucial support for an XID. They
+reveal the experience that's necessary to improve the progressive
+trust offered to a pseudonymous identity.
+
+To date, claims have all been detached. Often this is because claims
+are small enough that they shouldn't be cluttering up the XID Document
+that's fundamental to the description of an identity. But sometimes
+it's because claims are sensitive and may need to be hidden in various
+ways.
+
+This isn't always the case. There are claims (and other data) that are
+important enough that they should be linked to the XID in a more
+permanent way. They can still be elided: any data on a XID can be
+redacted to ensure data minmization. But, because of their importance,
+they need to be part of the default organization of a XID.
+
+This chapter will discuss a variety of ways to add data to a XID, with
+a focus on _edges_, which are a methodology for placing a claim
+directly on a XID.
+
+## Major Objectives for this Chapter
+
+After working through this chapter, a developer will be able to:
+
+- Create self-attestation edges
+- Create peer endorsement edges
+- Extract attestations from XIDs
+- Establish proof of control for a GitHub account
+- Build a Web of Trust
+
+Supporting objectives include the ability to:
+
+- Know different methodologies for linking data to XIDs
+- Understand the difference between self-attestations and peer endorsements
+- Know the value of relationship transparency
