+## Windows support
+
+Windows support is possible by running the Playwright process in a `ProactorEventLoop`
+in a separate execution thread.
+This is necessary because it's not possible to run the Playwright process in the same
+asyncio event loop as the crawler process:
+* Playwright runs the driver in a subprocess. Source:
+  [Playwright repository](https://github.com/microsoft/playwright-python/blob/v1.44.0/playwright/_impl/_transport.py#L120-L130).
+* "On Windows, the default event loop `ProactorEventLoop` supports subprocesses,
+  whereas `SelectorEventLoop` does not". Source:
+  [Python docs](https://docs.python.org/3/library/asyncio-platforms.html#asyncio-windows-subprocess).
+* Twisted's `asyncio` reactor requires the `SelectorEventLoop`. Source:
+  [Twisted repository](https://github.com/twisted/twisted/blob/twisted-24.3.0/src/twisted/internet/asyncioreactor.py#L31)

+Just like the [upstream Scrapy extension](https://docs.scrapy.org/en/latest/topics/extensions.html#module-scrapy.extensions.memusage), this custom memory extension does not work
+on Windows. This is because the stdlib [`resource`](https://docs.python.org/3/library/resource.html)
