+# alchemist
+
+Alchemist is a typst package to draw skeletal formulae. It is based on the [chemfig](https://ctan.org/pkg/chemfig) package. The main goal of alchemist is not to reproduce one-to-one chemfig. Instead, it aims to provide an interface to achieve the same results in Typst.
+
+<!--EXAMPLE(links)-->
+````typ
+#skeletize({
+  fragment(name: "A", "A")
+  single()
+  fragment("B")
+  branch({
+    single(angle: 1)
+    fragment(
+      "W",
+      links: (
+        "A": double(stroke: red),
+      ),
+    )
+    single()
+    fragment(name: "X", "X")
+  })
+  branch({
+    single(angle: -1)
+    fragment("Y")
+    single()
+    fragment(
+      name: "Z",
+      "Z",
+      links: (
+        "X": single(stroke: black + 3pt),
+      ),
+    )
+  })
+  single()
+  fragment(
+    "C",
+    links: (
+      "X": cram-filled-left(fill: blue),
+      "Z": single(),
+    ),
+  )
+})
+````

+
+Alchemist uses cetz to draw the molecules. This means that you can draw cetz shapes in the same canvas as the molecules. Like this:
+
+<!--EXAMPLE(cetz)-->
+````typ
+#skeletize({
+  import cetz.draw: *
+  double(absolute: 30deg, name: "l1")
+  single(absolute: -30deg, name: "l2")
+  fragment("X", name: "X")
+  hobby(
+    "l1.50%",
+    ("l1.start", 0.5, 90deg, "l1.end"),
+    "l1.start",
+    stroke: (paint: red, dash: "dashed"),
+    mark: (end: ">"),
+  )
+  hobby(
+    (to: "X.north", rel: (0, 1pt)),
+    ("l2.end", 0.4, -90deg, "l2.start"),
+    "l2.50%",
+    mark: (end: ">"),
+  )
+})
+````

+
+## Usage
+
+To start using alchemist, just use the following code:
+
+```typ
+#import "@preview/alchemist:0.1.9": *
+
+#skeletize({
+  // Your molecule here
+})
+```
+
+For more information, check the [manual](https://raw.githubusercontent.com/Typsium/alchemist/0.1.9/doc/manual.pdf).
+
+## Tests
+
+The test suite is managed with [tytanic](https://github.com/typst-community/tytanic).
