+= Introduction
+
+This package provides a way to make beautiful register diagrams using the CeTZ package. It can be used to document Assembly instructions or binary registers
+
+This is a port of the #link("https://git.kb28.ch/HEL/rivet")[homonymous Python script] for Typst. For more information on the schema format, please check out the original project's #link("https://git.kb28.ch/HEL/rivet/src/branch/main/format.md")[format.md]
+
+= Usage
+
+Simply import `schema` from #link("src/lib.typ") and call `schema.load` to parse a schema description. Then use `schema.render` to render it, et voilà !
+#pad(left: 1em)[```typ
+#import "src/lib.typ": schema
+#let doc = schema.load("path/to/schema.typ")
+#schema.render(doc)
+```]
+
+= Config presets
+
+Aside from the default config, some example presets are also provided:
+- #doc-ref("config.config", full: true): the default theme, black on white
+  #examples.config-config
+- #doc-ref("config.dark", full: true): a dark theme, with white text and lines on a black background
+  #examples.config-dark
+- #doc-ref("config.blueprint", full: true): a blueprint theme, with white text and lines on a blue background
+  #examples.config-blueprint
+
+#pagebreak(weak: true)
+
+= Reference
+
+#let doc-config = tidy.parse-module(
+  read("docs/config.typ"),
+  name: "config",
+  scope: (
+    doc-ref: doc-ref
+  )
+)
+#tidy.show-module(doc-config, sort-functions: false)
+
+#pagebreak()
+
+#let doc-schema = tidy.parse-module(
+  read("docs/schema.typ"),

+  scope: (
+    schema: schema,
+    doc-ref: doc-ref
