+# Merge-Refs
+
+A function that merges React refs into one. Filters out invalid (eg. falsy) refs as well and returns original ref if only one valid ref was given.
+
+## tl;dr
+
+- Install by executing `npm install merge-refs` or `yarn add merge-refs`.
+- Import by adding `import mergeRefs from 'merge-refs'`.
+- Use it in `ref` like so: `<div ref={mergeRefs(ref, someOtherRef)} />`
+
+## Accepted refs
+
+- Refs created using `createRef()`
+- Refs created using `useRef()`
+- Functional refs
+
+## Example
+
+```tsx
+function Hello() {
+  const ref1 = useRef<HTMLDivElement>(); // I'm going to be updated!
+  const ref2 = (element: HTMLDivElement) => {
+    // I'm going to be called!
+  };
+
+  return <div ref={mergeRefs(ref1, ref2)} />;
+}
+```
