+# Diff / Patch
+
+## Diff
+
+Use the Diff function to generate a sequence of edits that will transform one value into another.
+
+```typescript
+const E = Value.Diff(
+  // const E = [
+  { x: 1, y: 2, z: 3 }, //   { type: 'update', path: '/y', value: 4 },
+  { y: 4, z: 5, w: 6 } //   { type: 'update', path: '/z', value: 5 },
+); //   { type: 'insert', path: '/w', value: 6 },
+//   { type: 'delete', path: '/x' }
+// ]
+```
+
+## Patch
+
+Use the Patch function to apply a sequence of edits.
+
+```typescript
+const A = { x: 1, y: 2 };
+
+const B = { x: 3 };
+
+const E = Value.Diff(A, B); // const E = [
+//   { type: 'update', path: '/x', value: 3 },
+//   { type: 'delete', path: '/y' }
+// ]
+
+const C = Value.Patch<typeof B>(A, E); // const C = { x: 3 }
+```
