-Svgbob can create a nice graphical representation of your text diagrams.
+Svgbob is a utility tool and library for generating nice graphical representation from simple ascii diagrams.
+It uses a combination of characters which are readily available in your keyboards.
 
-Svgbob provides a cli which takes text as an input and creates an svg image as an output.
 
-[**Demo**](https://ivanceras.github.io/svgbob-editor/)
+Example ascii diagrams:
 
+Rectangles:
+```txt
++-------+    .--------.
+|       |    |        |
++-------+    `--------'
+```
+
+Circle and arcs:
+```txt
+
+    ____            __  __
+  ,'    `.        ,'      `.
+ /        \      /          \
+ \        /
+  `.____.'       \          /
+                  `.__  __.'
+
+```
