 # Typstry.jl
 
-## Introduction
+A package to access the Typst command-line interface.
 
-A package to access the `Typst` command-line interface.
+See also their [website](https://typst.app/),
+[documentation](https://typst.app/docs/),
+and [repository](https://github.com/typst/typst).
 
-## Showcase
+## Features
+
+- Macros to construct Typst strings and commands
+- Functions to construct and render documents
+
+### Planned
+
+- Convert Julia values to Typst strings
+- Explore rendering
+    - Unicode in the REPL?
+    - Other environments?
+
+## Installation
 
 ```julia
 julia> using Pkg: add
 
 julia> add(url = "https://github.com/jakobjpeters/Typstry.jl")
 
 julia> using Typstry
+```
 
-julia> file_name = "example.typ"
-
-julia> write(file_name, "Typst is cool")
+## Showcase
 
-julia> compile(file_name)
 ```
+julia> document = typst"""
+       #set page(width: 10cm, height: auto)
+       #set heading(numbering: "1.")
 
-## Planned features
+       = Fibonacci sequence
+       The Fibonacci sequence is defined through the recurrance relation
+       $F_n = F_(n-1) + F_(n-2)$. It can also be expressed in _closed form:_

+       $ F_n round(1 / sqrt(5) phi.alt^n), quad phi.alt = (1 + sqrt(5)) / 2 $
+
+       #let count = 8
+       #let nums = range(1, count + 1)
+       #let fib(n) = (
+           if n <= 2 { 1 }
+           else { fib(n - 1) + fib(n - 2) }
+       )
+
+       The first #count numbers of the sequence are:
+
+       #align(center, table(
+           columns: count,
+           ..nums.map(n => $F_#n$),
+           ..nums.map(n => str(fib(n))),
+       ))
+       """;
+
+julia> render(document);
+```
