+## Custom file input
+
+If you don’t like the look/feel of the button rendered by `@uppy/file-input`, feel free to forgo the plugin and use your own custom button on a page, like so:
+
+```html
+<input type="file" id="my-file-input">
+```
+
+Then add this JS to attach it to Uppy:
+
+```js
+const uppy = Uppy(...)
+const fileInput = document.querySelector('#my-file-input')
+
+fileInput.addEventListener('change', (event) => {
+  const files = Array.from(event.target.files)
+
+  files.forEach((file) => {
+    try {
+      uppy.addFile({
+        source: 'file input',
+        name: file.name,
+        type: file.type,
+        data: file
+      })
+    } catch (err) {
+      if (err.isRestriction) {
+        // handle restrictions
+        console.log('Restriction error:', err)
+      } else {
+        // handle other errors
+        console.error(err)
+      }
+    }
+  })
+})
