General

You can add comments to your model by selecting the appropriate Comment button in the toolbar and then placing a comment field in your model.

To edit an existing comment you can double-click it.

Formatting text

A special feature is that you can format the inserted text. To do this, use the Markdown syntax (https://www.markdownguide.org/basic-syntax/). Here are some examples for basic styles.

# Heading level 1
## Heading level 2
### Heading level 3
**bold text**
*italic text*

Changing size of images

Via Insert image you can select an image and a corresponding placeholder will be inserted in the text flow: ![](image:pls-sem_book_3rd.jpg)

To change the size of the image, you can add a width specification in pixels in the placeholder as follows: ![](image:pls-sem_book_3rd.jpg,200)
