To use Nyancoin, download and run the Nyancoin software.
When run for the first time, the entire blockchain will be downloaded. This can take several hours, but only has to be done once.
If restarting the software after a few hours or days, it will automatically 'catch up' when started, this may take a few minutes.
Version 1.3.0, 21 October 2016:
Windows 32 bit, zip file 10.8MB, SHA1 Hash: f06323fc78252b365890adecc77e8aa35c1bdc48
Windows 64 bit, zip file 11.2MB, SHA1 Hash: f3fc5174ecffce33492d68c79cd25757de1193f9
File hash values can be obtained/validated using tools such as the Microsoft File Checksum Integrity Verifier.
If upgrading from a previous version, then:
Configuration and block files etc. are the same, no need to change anything else or download the blockchain again. Any shortcuts or links to the software will still work as before.
As with all software, regular backups are recommended, particularly the wallet which contains the keys to whatever Nyancoin you may own.
For a new installation:
The current version of the software does NOT open firewall ports automatically. Therefore if possible, please set port 33701 to accept incoming connections. For home use, this is usually done in your router configuration.
If you can't do this, then the software will still function - it just means that you can create connections to others, but they cannot connect to you.

The process should be similar to the Windows information above. Downloading the blockchain for the first time will take several hours - but only has to be done once.
Current (June 2016): https://github.com/Nyancoins/nyancoin-client
Build instructions are in /doc/build-unix.txt for the command line only version.
Or see /doc/readme-qt.rst for the QT graphical interface version.
The software uses port 33701 for connections so this must be set to open in your firewall configuration.
The block files and index currently require about 1.4GB of disk space, and the software can be run on most low-end virtual servers. For best performance, 1GB of RAM is suggested, although it will run with less.
The older versions are not recommended for use. They are years out of date and not supported or maintained by anyone.
If you really want to use them, they can be found here, however for any normal purposes you should be using the current versions as shown above.
