+# paekli-rs
+
+> [!Note]
+>
+> This was first created as part of an internal Rust workshop.
+> It is not quite ready yet to be used by the general public.
+> I intend to fix that post-haste.
+
+This is a guide for a toy project in Rust.
+It is intended as the next thing to do after reading [The Rust Programming Language](https://doc.rust-lang.org/book/).
+
+The focus is on bridging the gap between _the book_ and production-ready code, emphasizing among other things:
+- inter-process communication of several types
+- integration in a polyglot environment
+- automated testing and deployment (CI/CD)
+
+The guide is deployed at https://senekor.github.io/paekli-rs/.
