+# Topen - super simple taskwarrior note editing
+
+A script without bells and whistles.
+Focuses on letting you quickly:
+
+- create notes for taskwarrior tasks
+- edit notes for taskwarrior tasks
+
+Does both by simply being invoked with `topen <task-id>`.
+
+Automatically appends a small 'Note' annotation to your task so you know you have notes.
+
+<!-- TODO: Implement configuration options -->
+Should just work as-is without additional configuration in most taskwarrior setups.
+But can be configured through environment variables or cli options, see below.
+
+Can be used as-is or directly from taskwarrior by being aliased:
+
+```conf
+alias.note=exec topen
+```
+
+And you can open any note with your usual taskwarrior workflow,
+by doing `task note <id>`.
+
+That's all there is to it.
