# Labware Layouts

## Deck Layout

The first thing labware layouts do is indicate what labware and what instruments go where. This information is also available in the Opentrons App.

## Reagent Layout

The crucial aspect of labware layout files is discerning which reagents, volumes, and concentrations go where. These files contain input fields to define experiment dimensions, automatically populating various fields. StainWorks also does these setups, the difference being StainWorks outputs robot-friendly code, while labware layouts produce human-readable spreadsheets. Below is a screenshot illustrating the CODEX protocol, among our more intricate staining protocols:
