## Overview

This is a beginner-oriented Elixir learning repository, not a single application: learners start with the guide and progress through language concepts and runnable examples. The README describes broader Elixir capabilities, while the tree provides focused examples; sampled source is limited, so links between example topics are not inferred.

Main entry points: [`README.md`](https://github.com/dwyl/learn-elixir/blob/main/README.md) (Getting started guide), [`learn-elixir-on-livebook.livemd`](https://github.com/dwyl/learn-elixir/blob/main/learn-elixir-on-livebook.livemd) (Livebook guide), [`examples/basic-types`](https://github.com/dwyl/learn-elixir/tree/main/examples/basic-types) (Basic types), [`examples/lists`](https://github.com/dwyl/learn-elixir/tree/main/examples/lists) (Collections and maps)
