# Getting started

These sections should provide you with all the information needed to install the @polkadot/api package, understand the structure of the interfaces and allow you to start using it. For existing users this really should be titled "Things I wish I knew before I started using the api" - it really aims to close the gap to allow anybody to get to grips with using the packages.

# What this is not

This is not line-by-line documentation of all the existing function calls available, nor it is tied to a specific chain. (Although the examples do refer to the base Polkadot & Substrate chains). There will be some things in the API that are probably not covered, which brings us to the next point...

# Help us help others

If you spot gaps in the information provided, or are uncertain about any specific area, please do log an issue or if you are that way inclined, make a pull-request. We really want to have good documentation in these areas and allow people to be productive right from the start.

# Ready? Steady? Go!

If you already have a good grasp on the API and are just looking for a specific answer, you may want to take a look at the Frequently Asked Questions. With all that said, let's get started... What should be installed, and how should we do it?
