Bitcoin Core
=============
Setup
---------------------
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit [bitcoincore.org](https://bitcoincore.org/en/releases/).
Running
---------------------
The following are some helpful notes on how to run Bitcoin Core on your native platform.
### Unix
Unpack the files into a directory and run:
- `bin/bitcoin-qt` (GUI) or
- `bin/bitcoind` (headless)
### Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
### macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
### Need Help?
* See the documentation at the [Bitcoin Wiki](https://en.bitcoin.it/wiki/Main_Page)
