-# Passing values example
-
-This example demonstrates how to pass values to Typst, which can be useful in rendering custom documents such as reports, invoices, and more.
-
-## How it works
-
-This example follows the [template pattern](https://typst.app/docs/tutorial/making-a-template/) described in the Typst documentation.
-Here is a short overview of the files:
-
-- [template.typ](template.typ) defines a Typst template function that constructs a document based on parameters.
-- [main.go](main.go) shows how to convert/encode Go values into Typst markup, and how to call/render the template with these converted values.
-- [template-preview.typ](template-preview.typ) also invokes the template while providing mock data.
-    This is useful when you want to preview, update or debug the template.

-# Simple example
-
-This example shows how to render Typst documents directly from strings in Go.
-
-## The pros and cons
-
-The main advantage of this method is that it's really easy to set up.
-In the most simple case you build your Typst markup by concatenating strings, or by using `fmt.Sprintf`.
-
-The downside is that the final Typst markup is only generated on demand.
-This means that you can't easily use the existing Typst tooling to write, update or debug your Typst markup.
-Especially as your your documents get more complex, you should switch to other methods.
