  - Configuration of the indentation of the levels of the table.
  - Option to add to the elements of the table link to each section.
 
+### How is the indentation added?
+
+The indentation of each level of the table is just a set of ` `, styled with `white-space: pre;`, to make the browser preserve them.
+
+### How are the links added?
+
+The links are added by adding an `id` attribute to each title appearing in the table of contents, but only if it doesn't have it; original `id` attributes are not overwritten, not to break any other possible reference.
+
+The format of the generated `id` is `section_x`, `section_x_y`, etc. Then, the link is just a hyperlink to the `id` (e.g., `<a href="#section_x">Section X</a>`).

 ## Installation
  1. Download it (check the [releases section](https://github.com/julenpardo/tinymce-table-of-contents/releases)).
  2. Unzip the contents into a `table-of-contents` named folder.
