+Hi!
+
+This is an Alpine Linux repository of random packages I find useful, but
+not quite fitting into the official aports repo.
+
+All the stuff here is built from https://git.ddd.rip/ptrcnull/ptrcports,
+currently the main supported architectures are x86_64 and aarch64.
+
+Adding into your system (as root):
+echo "@ptrc https://repo.ptrc.pl/ptrcports" >> /etc/apk/repositories
+apk add --update --allow-untrusted ptrcports-keys@ptrc
+
+After that, you can add packages via `apk add package-name@ptrc`.
