 # CCash-2.0
+
 A complete simplification and improvement to the CCash project. A webserver hosting a bank system for Minecraft, able to be used from web browser or from CC/OC if you're playing modded.
 
 #### Build

 #### Dependencies
-* [Parallel HashMap](https://github.com/greg7mdp/parallel-hashmap/tree/master)
-* [drogon web framework (and all its dependencies)](https://github.com/an-tao/drogon/tree/master)

 # Features
+
 ### Performance
-* multi-threaded
-* parallel hashmaps, a far superior HashMap implementation to the STD, that also benefit from multi-threaded
-* written in C++, **arguably** the fastest language
-* **NOT** written in Lua

 ### Safety
-* OpenSSL (HTTPS)
-* Very difficult to tamper with compared to an in-game implementation of a bank
-* Auto-Saving, Save on close, are in place
-### Accessibility  
-* able to be used millions of blocks away, across dimensions, servers, vanilla or modded, or outside of the game entirely

 # Improvements from 1.0
-* frequency/on-close saving in contrast to every change resulting in a Save() call
-* multi-threaded
-* near infinite number of users rather then 2^16
-* no account vs user distinction, it was complicating usage without much gain
-* OpenSSL
-* a web based frontend
