# Get Started

# Introduction

As this is a package extension, if you are new to `{admiral}` then the best place to first start reading would be this Get Started guide. This extension package follows the same main idea and conventions, and re-uses many functions from `{admiral}`, so it is important to thoroughly understand these to be able to use `{admiralophtha}`.

# Derivations

The most important functions in `{admiralophtha}` are the derivations. Again these follow the same conventions as `{admiral}` but are focused to ophthalmology-specific needs.

# Starting a Script

For the ophthalmology ADaM data structures, an overview of the flow and example function calls for the most common steps are provided by the following vignettes:

- Creating ADBCVA
- Creating ADOE
- Creating ADVFQ

# Support

Support is provided via the admiral Slack channel.
