+	  Bitcoin Core is an open source project which maintains and
+	  releases Bitcoin client software called “Bitcoin Core”.
+
+	  It is a direct descendant of the original Bitcoin software
+	  client released by Satoshi Nakamoto after he published the
+	  famous Bitcoin whitepaper.
+
+	  Bitcoin Core consists of both "full-node" software for fully
+	  validating the blockchain as well as a bitcoin wallet. The
+	  project also currently maintains related software such as
+	  the cryptography library libsecp256k1 and others located at
+	  GitHub.
