 The AtomicDEX API core is open-source [atomic-swap](https://komodoplatform.com/en/academy/atomic-swaps/) software for seamless, decentralised, peer to peer trading between almost every blockchain asset in existence. This software works with propagation of orderbooks and swap states through the [libp2p](https://libp2p.io/) protocol and uses [Hash Time Lock Contracts (HTLCs)](https://en.bitcoinwiki.org/wiki/Hashed_Timelock_Contracts) for ensuring that the two parties in a swap either mutually complete a trade, or funds return to thier original owner.

 A [well documented API](https://developers.komodoplatform.com/basic-docs/atomicdex/introduction-to-atomicdex.html) offers simple access to the underlying services using simple language agnostic JSON structured methods and parameters such that users can communicate with the core in a variety of methods such as [curl](https://developers.komodoplatform.com/basic-docs/atomicdex-api-legacy/buy.html) in CLI, or fully functioning [desktop and mobile applications](https://atomicdex.io/) like [AtomicDEX Desktop](https://github.com/KomodoPlatform/atomicDEX-Desktop).

 The coins file contains information about the coins and tokens you want to trade. A regularly updated version is maintained in the [Komodo Platform coins repository](https://github.com/KomodoPlatform/coins/blob/master/coins). Pull Requests to add any coins not yet included are welcome.
 
+To facilitate interoperability with the `mm2` service, there is the `adex-cli` command line utility. It provides a questionnaire initialization mode to set up the configuration and obtain the proper coin set through the internet. It can also be used to start or stop the service.
