 ## Getting Started
 
 ```bashl
-npm install -g bitcore-node-dash@latest
-bitcore-node-dash create mynode
+npm install -g bitcore-node-pivx@latest
+bitcore-node-pivx create mynode
 cd mynode

 ## Prerequisites
 
-- [Bitcore Node Dash 3.x](https://github.com/dashpay/bitcore-node-dash)
+- [Bitcore Node PIVX 3.x](https://github.com/PIVX-Project/bitcore-node-pivx)
 
-**Note:** You can use an existing Dash data directory, however `txindex`, `addressindex`, `timestampindex` and `spentindex` needs to be set to true in `dash.conf`, as well as a few other additional fields.
