+# Supporting Bitcoin Core Users
+
+This site tells Bitcoin Core users where they can [go to find help][bcc
+help]---but that help is provided by volunteers like you. Many questions
+are asked by complete newbies, so nearly everyone with any experience
+using Bitcoin Core can provide help.
+
+Before you start providing support, you may want to familiarize yourself
+with the available [documentation][bcc documentation].
+
+## Forums
+
+The following forums are where we believe most users ask their Bitcoin
+Core questions.
+
+- [Bitcoin StackExchange][] is a community dedicated entirely to
+  answering questions about Bitcoin and related technology.  Many
+  questions about Bitcoin Core can be found under the [Bitcoin-Qt
+  tag][bitcoin stackexchange tag bitcoin-qt]
+
+- [BitcoinTalk Technical Support][forum tech support] is a
+  sub-forum dedicated to providing help for Bitcoin Core and other
+  Bitcoin programs.
+
+- [/r/Bitcoin][bitcoin reddit] is a Reddit community that occasionally
+  features questions about Bitcoin Core. Currently, very few questions
+  receive enough upvotes to be featured on the front page, but you can
+  always check the [new queue][bitcoin reddit new] or answer questions
+  on the popular Mentor Monday thread (usually posted around noon UTC
+  on Monday).
+
+- [/r/BitcoinBeginners][bitcoin beginners] is a Reddit community that
+  prominently features questions from inexperienced Bitcoin users.
+
+## Live
+
+Internet Relay Chat (IRC) is the most popular way to get live online
+help with Bitcoin Core.  When providing links to documentation, most
+chatrooms require you post full links (not links shortened using
+services like TinyURL or Bit.ly).
+
+The links below will get you started using an IRC web interface.  Many
+serious IRC users use a [native IRC client][].
+
+- [#bitcoin][] is where most users should ask general questions about
+  Bitcoin Core.
+
+- [#bitcoin-mining][] hosts discussion about Bitcoin mining, including
+  decentralized mining using Bitcoin Core as part of the system.
+
+- For more channels, please see the [comprehensive
+  listing][irc channels] on the Bitcoin Wiki.
