+    longDescription= ''
+      Bitcoin is a free open source peer-to-peer electronic cash system that is
+      completely decentralized, without the need for a central server or trusted
+      parties. Users hold the crypto keys to their own money and transact directly
+      with each other, with the help of a P2P network to check for double-spending.
+
+      We call our code repository Bitcoin Classic. It starts as a one-feature patch
+      to bitcoin-core that increases the blocksize limit to 2 MB. We will have
+      ports for master and 0.11.2, so that miners and businesses can upgrade to 2 MB
+      blocks from any recent bitcoin software version they run. In the future we will
+      continue to release updates that are in line with Satoshi’s whitepaper &
+      vision, and are agreed upon by the community.
