 # chronos
 
 A Typst package to draw sequence diagrams with CeTZ
+
+---
+
+This package lets you render sequence diagrams directly in Typst. The following boilerplate code creates an empty sequence diagram with two participants:
+
+<table>
+<tr>
+<td><strong>Typst</strong></td>
+<td><strong>Result</strong></td>
+</tr>
+<tr>
+<td>
+
+```typst
+#import "@preview/chronos:0.1.0"
+#chronos.diagram({
+  import chronos: *
+  _par("Alice")
+  _par("Bob")
+})
+```
+
+</td>
+<td><img src="./gallery/readme/boilerplate.png"></td>
+</tr>
+</table>
+
+> *Disclaimer*\
+> The package cannot parse PlantUML syntax for the moment, and thus requires the use of element functions, as shown in the examples.
+> A PlantUML parser is in the TODO list, just not the top priority
+
+## Basic sequences
+
+You can make basic sequences using the `_seq` function:
+
+<table>
+<tr>
+<td><strong>Typst</strong></td>
+<td><strong>Result</strong></td>
+</tr>
+<tr>
+<td>
+
+```typst
+#chronos.diagram({
+  import chronos: *
+  _par("Alice")
+  _par("Bob")
+
+  _seq("Alice", "Bob", comment: "Hello")
+  _seq("Bob", "Bob", comment: "Think")
+  _seq("Bob", "Alice", comment: "Hi")
+})
+```
+
+</td>
+<td><img src="./gallery/readme/simple_sequence.png"></td>
+</tr>
+</table>
+
+You can make lifelines using the following parameters of the `_seq` function:
+ - `enable-dst`: enables the destination lifeline
+ - `create-dst`: creates the destination lifeline and participant
+ - `disable-dst`: disables the destination lifeline
+ - `destroy-dst`: destroys the destination lifeline and participant
+ - `disable-src`: disables the source lifeline
+ - `destroy-src`: destroy the source lifeline and participant
+
+<table>
+<tr>
+<td><strong>Typst</strong></td>
+<td><strong>Result</strong></td>
+</tr>
+<tr>
+<td>
+
+```typst
+#chronos.diagram({
+  import chronos: *
+  _par("A", display-name: "Alice")
+  _par("B", display-name: "Bob")
+  _par("C", display-name: "Charlie")
+  _par("D", display-name: "Derek")
+

+  _seq("B", "B", comment: "self call", enable-dst: true)
+  _seq("C", "B", comment: "hello from thread 2", enable-dst: true, lifeline-style: (fill: rgb("#005500")))

+  _seq("B", "A", comment: "success", disable-src: true, dashed: true)
+})
+```

+## Showcase
+
+Several features have already been implemented in Chronos. Don't hesitate to checkout the examples in the [gallery](./gallery) folder to see what you can do. 
+
+#### Quick example reference:
+<table>
+<tr>
+<td><strong>Example</strong></td>
+<td><strong>Features</strong></td>
+</tr>
+<tr>
+<td>
+
+`example1` <br>([PDF](./gallery/example1.pdf)|[Typst](./gallery/example1.typ))
+
+</td>
+<td>Simple cases, color sequences, groups, separators, gaps, self-sequences</td>
+</tr>
+<tr>
+<td>
+
+`example2` <br>([PDF](./gallery/example2.pdf)|[Typst](./gallery/example2.typ))
+
+</td>
+<td>Lifelines, found/lost messages, synchronized sequences, slanted sequences</td>
+</tr>
+<tr>
+<td>
+
+`example3` <br>([PDF](./gallery/example3.pdf)|[Typst](./gallery/example3.typ))
+
+</td>
+<td>Participant shapes, sequence tips, hidden partipicant ends</td>
+</tr>
+<tr>
+<td>
+
+`notes` <br>([PDF](./gallery/notes.pdf)|[Typst](./gallery/notes.typ))
+
+</td>
+<td>Notes (duh), deferred participant creation</td>
+</tr>
+</table>

+> [!NOTE]
+> 
+> Many examples were taken/adapted from the PlantUML [documentation](https://plantuml.com/sequence-diagram) on sequence diagrams
