 ## Installation
 ## Requirements
 
-  - A wallet address (DeNet app/Metamask/any other wallet) holding a Datakeeper Node License.
-  - Device with free disk space for storing DeNet user data.
-  - Terminal access (Command Prompt/PowerShell on Windows, Terminal on macOS/Linux).
-  - DeNet Node application downloaded.
-  - PEAQ balance: tokens will be distributed to Datakeepers automatically and will be regularly credited for successfully completed transactions, if the node is running and does not disconnect from the network, no deposits will be required.
