+### What it does
+Checks for usage of indexing or slicing. Arrays are special cases, this lint
+does report on arrays if we can tell that slicing operations are in bounds and does not
+lint on constant `usize` indexing on arrays because that is handled by rustc's `const_err` lint.
+
+### Why is this bad?
+Indexing and slicing can panic at runtime and there are
+safe alternatives.
+
+### Example
+```
+// Vector
+let x = vec![0; 5];
+
+x[2];
+&x[2..100];
+
+// Array
+let y = [0, 1, 2, 3];
+
+&y[10..100];
+&y[10..];
+```
+
+Use instead:
+```
+
+x.get(2);
+x.get(2..100);
+
+y.get(10);
+y.get(10..100);
+```
