+### Dynamic handle positions / Adding handles dynamically
+
+When working with dynamic handle positions or adding handles dynamically, you need to use
+the [`updateNodeInternals`](/typedocs/types/UpdateNodeInternals.html/) method.
+
+You need to call this method otherwise your node will not respond to the new handles and edges will be 
+misaligned.
+
+You can either use the store action to update multiple nodes at once by passing their ids into the method, 
+or you can emit the `updateNodeInternals` event from your custom node component without passing any parameters.
+
+#### Examples
+
+- Using store action
+
+```vue:no-line-numbers
+<script setup>
+import { useVueFlow } from '@braks/vue-flow'
+
+const { updateNodeInternals } = useVueFlow()
+
+const onSomeEvent = () => {
+  updateNodeInternals(['1'])
+}
+</script>
+```
+
+- Emitting event from custom component
+
+```vue:no-line-numbers
+<script setup>
+const emits = defineEmits(['updateNodeInternals'])
+
+const onSomeEvent = () => {
+  emit('updateNodeInternals')
+}
+</script>
