Create an Article
Whenever you have a piece of information that you want to share with users who have the appropriate level of access in a particular project, you can add an article to the knowledge base.
When you add an article to the knowledge base, it is created as a draft. Your drafts are only available to you, even when the visibility restrictions for the article are undefined.
This means that you can take all the time you need to polish the article to perfection before you publish and share it with a larger audience.
If you're writing the first knowledge base article for a project, the project name is not yet displayed in the knowledge base navigation menu. Click New Article in the application header. When an empty draft opens, click Select project to locate the project name in the list.
Once you have one or more articles in a project, whether published or in draft form, you can add articles and sub-articles using the controls in the table of contents in the side panel.
To create your first article in a project:
Click the Knowledge Base link in the application header.
Click the New Article button, which is also located in the header.
The page displays a new, untitled draft.
Click Select project and select a project name from the list.
The article draft is listed in the Drafts section in the table of contents.
Give your article a title by typing directly into the Title field.
Enter or paste the article content into the content editor.
