+# Eólas
+
+> Eólas is Irish for knowledge or information, especially knowledge gained by
+> experience or practice
+
+This repository contains notes from my autodidactic study of software
+engineering and computer science.
+
+It is a [Zettelkasten]() work in progress. I've recently converted the
+topic-based subdirectories into a single flat directory structure organised by
+tags. I'm in the process of partitioning longer notes into smaller informational
+units.
+
+I use the [zk](https://github.com/zk-org/zk) CLI package to help with indexing
+and task automation alongside its [zk-nvim](https://github.com/zk-org/zk-nvim)
+Neovim wrapper.
