**Envoy** is a messenger written in Java.<br>
It is split into three separate components: Envoy Client, Envoy Common and Envoy Server.
<br><br><br><br><br>
---
### Envoy Client:
This is the only part users are interested in. It contains everything to make this messenger work: the UI.
### Envoy Server:
Envoy offers the option to download and host your own server over which Envoy can run.<br>
This part will be especially appealing to institutions/organizations who want to self-host Envoy.
### Envoy Common:
This part contains elements that both the client and the server need. It will be automatically part of either one (Thanks, Maven!).
## Features
Envoy features a lot of things and many more are yet to come.
Currently existing features are:
#### 'Client' contains:
* typical Messenger features (sending and receiving of messages, groups, sending images and voice messages)
* typical Messenger feeling (displaying unread messages)
* Appealing user interface (UI)
* Programming
* API to change default configuration
* Advanced logging possibilities
* Tons of Events to interact with
* Detailed Javadoc to improve readability of code
#### 'Common' contains:
* the event system
* the logger
* Envoy-specific Exceptions
* some util classes
* the most basic datatypes
#### 'Server' contains:
* the database implementation of the data classes
* the connectivity classes
* processors to handle incoming events
* Utility classes to check client version compatability and Password validity
