+# Modelling A Ticket
+
+The first chapter should have given you a good grasp over some of Rust's primitive types, operators and 
+basic control flow constructs.  
+In this chapter we'll go one step further and cover what makes Rust truly unique: **ownership**.  
+Ownership is what enables Rust to be both memory-safe and performant, with no garbage collector.
+
+As our running example, we'll use a (JIRA-like) ticket, the kind you'd use to track bugs, features, or tasks in
+a software project.  
+We'll take a stab at modeling it in Rust. It'll be the first iteration—it won't be perfect nor very idiomatic 
+by the end of the chapter. It'll be enough of a challenge though!  
+To move forward you'll have to pick up several new Rust concepts, such as:
+
+- `struct`s, one of Rust's ways to define custom types
+- Ownership, references and borrowing
+- Memory management: stack, heap, pointers, data layout, destructors
+- Modules and visibility
+- Strings
+
