 # Djot
 
 A fast [Djot](https://djot.net) parser and formatter for Elixir.
+
+Djot parsing and transformations powered by the [jotdown](https://crates.io/crates/jotdown) rust crate.
+
+## Goals
+- [x] Fast Djot to HTML transforms
+- [ ] Precompiled binary
+- [ ] Optional sanitization
+- [ ] Syntax highlighting via autumn or inkjet
+
+## Usage
+
+Simply call `to_html` on a string that contains Djot data, and you'll get back a html fragment.
+
+```elixir
+
+Djot.to_html("hello *world*!")
+# => {:ok, "<p>hello <strong>world</strong>!</p>\n"}
+```
+
+## Installation
+
+Add `:djot` as a dependency:
+
+```elixir
+def deps do
+[
+  {:djot, "~> 0.1.0"}
+]
+```
