 Your effects run after the component has been mounted to the DOM, and in a [microtask](https://developer.mozilla.org/en-US/docs/Web/API/HTML_DOM_API/Microtask_guide) after state changes. Re-runs are batched (i.e. changing `color` and `size` in the same moment won't cause two separate runs), and happen after any DOM updates have been applied.
 
-You can place `$effect` anywhere, not just at the top level of a component, as long as it is called during component initialization (or while a parent effect is active). It is then tied to the lifecycle of the component (or parent effect) and will therefore destroy itself when the component unmounts (or the parent effect is destroyed).
+Effects must be executed within a parent effect, which can be the `$effect.root`, another `$effect`, or `$effect.pre`. You can place an `$effect` anywhere, not just at the top level of a component, as long as it is called during component initialization (or while a parent effect is active). It is then tied to the lifecycle of the component (or parent effect) and will therefore destroy itself when the component unmounts (or the parent effect is destroyed).
 
 You can return a function from `$effect`, which will run immediately before the effect re-runs, and before it is destroyed ([demo](/playground/untitled#H4sIAAAAAAAAE42RQY-bMBCF_8rI2kPopiXpMQtIPfbeW6m0xjyKtWaM7CFphPjvFVB2k2oPe7LmzXzyezOjaqxDVKefo5JrD3VaBLVXrLu5-tb3X-IZTmat0hHv6cazgCWqk8qiCbaXouRSHISMH1gop4coWrA7JE9bp7PO2QjjuY5vA8fDYZ3hUh7QNDCy2yWUFzTOUilpSj9aG-linaMKFGACtKCmSwvGGYGeLQvCWbtnMq3m34grajxHoa1JOUXI93_V_Sfz7Oz7Mafj0ypN-zvHm8dSAmQITP_xaUq2IU1GO1dp80I2Uh_82dao92Rl9R8GvgF0QrbrUFstcFeq0PgAkha0LoICPoeB4w1SJUvsZcj4rvcMlvmvGlGCv6J-DeSgw2vabQnJlm55p7nM0rcTctYei3HZxZSl7XHVqkHEM3k2zpqXfFyj393zU05fpyI6f0HI0hUoPoamC9roKDeo2ivBH1EnCQOmX9NfYw2GHrgCAAA=)).
