![Types of Notebook cells](/files/zfx5HL8CRcUAqUJo4Gmk)

A Notebook under the DS Lab plugin is a collection of cells. Cells that contain either explanatory text (Markdown) or executable code and its output. Click a cell to select it.

You can add new cells by using the [**+Code**](/bdb-documentation/data-science-lab/various-tabs-to-work-with/notebook/notebook-page/notebook-cells/using-a-code-cell.md) and [**+Markdown**](/bdb-documentation/data-science-lab/various-tabs-to-work-with/notebook/notebook-page/notebook-cells/using-a-markdown-cell.md) options given at the bottom of the cell.
