+# Generating documentation of the code
+
+It is now possible for developers to create a local documentation website showing the source code of the Tasks plugin.
+
+This can help gain an understanding of the code, and see relationships between classes and functions.
+
+## Generating the documentation
+
+```bash
+yarn code-docs
+```
+
+This runs [TypeDoc](https://typedoc.org) to populate `code-docs/index.html` and related files.
+
+See the `typedocOptions` section in [tsconfig.json](https://github.com/obsidian-tasks-group/obsidian-tasks/blob/main/tsconfig.json) for options used.
+
+## Launching the documentation
+
+In WebStorm, use the following steps to view the generated documentation:
+
+1. Open `code-docs/index.html`
+2. Click on a browser icon to open the file in a browser of your choice.

+
+## Using the documentation
+
+A page like this (the Index) will open.

+
+1. Use the links on the left to browse the source code and its documentation.
+2. The `Class Hierarchy` is especially useful.
+3. When viewing classes and files, these Settings will be useful.
+4. Click on the title to get back this Index page.
+
+## Class Hierarchy
+
+Here is a sample screenshot showing the class hierarchy:
