+# About the Bitcoin Core pages on Bitcoin.org
+
+Bitcoin.org hosts several pages about Bitcoin Core as well as the
+[Bitcoin Core downloads][bcc download], but the Bitcoin.org and Bitcoin
+Core open source projects are run by separate teams.
+
+## History
+
+Bitcoin.org was originally used by [Satoshi Nakamoto][] to host his
+[Bitcoin paper][bitcoinpdf]. Soon after, it began linking to
+downloadable versions of the original Bitcoin software, making it the
+homepage for the Bitcoin program.
+
+New educational content about Bitcoin was added to Bitcoin.org over
+time, but that home page remained even when the name of the original
+program was changed to Bitcoin Core.
+
+In the years since, the amount of content on Bitcoin.org has continued
+to increase.  There's more content about Bitcoin Core than ever before
+and also more content about other Bitcoin software and resources.
+
+## Separation of concerns
+
+As of Dec 2015, Bitcoin.org has 876 pages in 25 different languages,
+but fewer than 100 of those pages belong to Bitcoin Core. The Bitcoin
+Core project has no control over those non-Core pages or any polices
+enacted on them.
+
+Likewise, content provided through the Bitcoin Core pages is not
+necessarily endorsed or supported by the Bitcoin.org contributors.
+
+## Maintenance
+
+Pull requests and issues directly relating to Bitcoin Core are tagged as
+*[Core][core github tag]* in the Bitcoin.org repository.
