+    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.
+      
+      The Bitcoin Unlimited (BU) project seeks to provide a voice to all
+      stakeholders in the Bitcoin ecosystem.
+
+      Every node operator or miner can currently choose their own blocksize limit
+      by modifying their client. Bitcoin Unlimited makes the process easier by
+      providing a configurable option for the accepted and generated blocksize via
+      a GUI menu. Bitcoin Unlimited further provides a user-configurable failsafe
+      setting allowing you to accept a block larger than your maximum accepted
+      blocksize if it reaches a certain number of blocks deep in the chain.
+
+      The Bitcoin Unlimited client is not a competitive block scaling proposal
+      like BIP-101, BIP-102, etc. Instead it tracks consensus. This means that it
+      tracks the blockchain that the hash power majority follows, irrespective of
+      blocksize, and signals its ability to accept larger blocks via protocol and
+      block versioning fields.
+
+      If you support an increase in the blocksize limit by any means - or just
+      support Bitcoin conflict resolution as originally envisioned by its founder -
+      consider running a Bitcoin Unlimited client.
