 ## Why?
 
 This library (and [its](https://git.nocturn9x.space/nocturn9x/giambio) [predecessors](https://git.nocturn9x.space/nocturn9x/aiosched)) is just a way for me to test my knowledge and make sure I understand the basics of structured concurrency
-and building solid coroutine runners so that I can implement the paradigm in my own programming language. For more info, see [here](https://git.nocturn9x.space/nocturn9x/peon).

+**P.S.**: structio is only thoroughly tested for Linux: While Windows/macOS support is one of the goals
+of the project, I currently don't have enough time to dedicate to the quirks of the I/O subsystem of each OS.
+All features that don't rely on I/O (timeouts, events, queues, memory channels, etc.) are cross-platform, but
+things like sockets behave very differently depending on the platform, and it'll take some time for me to
+apply the necessary fixes for each of them. File I/O (in its current form using threads), as well as asynchronous
+threads and processes _should_ work, but there's no guarantee
