+## The `define_clippy_lints` macro
+
+After `cargo dev new_lint`, you should see a macro with the name `define_clippy_lints`. It will be in the same file if you defined a standalone lint, and it will be in `mod.rs` if you defined a type-specific lint.
+
+The macro looks something like this:
+
+```rust
+declare_clippy_lint! {
+	/// ### What it does
+    ///
+	/// // Describe here what does the lint do.
+	/// 
+	/// Triggers when detects...
+	/// 
+    /// ### Why is this bad?

+	/// // Describe why this pattern would be bad

+    /// ```rust
+    /// // example code where clippy issues a warning

+    /// Use instead:
+    /// ```rust
+    /// // example code which does not raise clippy warning
