+L<WinCompose|https://github.com/samhocevar/wincompose> adds
+L<compose key|https://en.wikipedia.org/wiki/Compose_key> functionality to Windows.
+It can be installed either via the L<WinCompose releases|https://github.com/samhocevar/wincompose/releases>
+page on GitHub, or with the L<Chocolatey package manager|https://chocolatey.org/packages/wincompose>.
+
+Once the program is installed and running, right click the tray icon and
+select C<Options → General → Compose Key> to set your desired key.
+
+WinCompose uses L<kragen/xcompose|https://github.com/kragen/xcompose> as
+a source, so by default has plenty of useful sequences available.
+These sequences can be viewed by right clicking the tray icon and selecting C<Show Sequences>.
+If you wish to add your own sequences, you can do so by either adding/modifying
+C<.XCompose> in C<%USERPROFILE%>, or editing user-defined sequences in the options menu.
