+
+A cancelable reader for Go
+
+This package is based on the fantastic work of [Erik Geiser](https://github.com/erikgeiser)
+in Charm's [Bubble Tea](https://github.com/charmbracelet/bubbletea) framework.
+
+## Usage
+
+`NewReader` returns a reader with a `Cancel` function. If the input reader is a
+`File`, the cancel function can be used to interrupt a blocking `Read` call.
+In this case, the cancel function returns true if the call was canceled
+successfully. If the input reader is not a `File`, the cancel function does
+nothing and always returns false.
+
+```go
+r, err := cancelreader.NewReader(file)
+if err != nil {
+    // handle error
+    ...
+}
+
+// cancel after five seconds
+go func() {
+    time.Sleep(5 * time.Second)
+    r.Cancel()
+}()
+
+// keep reading
+for {
+    var buf [1024]byte
+    _, err := r.Read(buf[:])
+
+    if errors.Is(err, cancelreader.ErrCanceled) {
+        fmt.Println("canceled!")
+        break
+    }
+    if err != nil {
+        // handle other errors
+        ...
+    }
+
+    // handle data
+    ...
+}
+```
+
+## Implementations
+
+- The Linux implementation is based on the epoll mechanism
+- The BSD and macOS implementation is based on the kqueue mechanism
+- The generic Unix implementation is based on the posix select syscall
+
+## Caution
+
+The Windows implementation is based on WaitForMultipleObject with overlapping
+reads from CONIN$. At this point it only supports canceling reads from
+`os.Stdin`.
