+# Writing Bitcoin Core Documentation
+
+Bitcoin Core documentation is spread across three projects: Bitcoin
+Core, the Bitcoin Wiki, and Bitcoin.org---and is further subdivided into
+different parts. The sections below briefly describe what documentation
+is available and how you can contribute.
+
+## Bitcoin Core Docs Directory
+
+The [docs directory][bitcoin core docs directory]
+contains various files describing aspects of Bitcoin Core. Almost all of
+the files are meant for developers and testers rather than users, although
+some (such as the build instructions) may be used by power users.
+
+The files are all written in Markdown, which can be easily edited in
+GitHub's web interface:
+
+1. Create a GitHub account, or if you already have one, log in.
+
+2. Find the file you want to edit. For example, [build-unix.md][bitcoin
+   core build unix]
+
+3. Click the Edit icon (a pencil).
+
+4. Make your change and click the Preview button to preview it. Revise
+   and edit until you're happy with it.
+
+5. At the bottom of the page, fill out the Propose File Change form and
+   submit it.
+
+*Need help getting started?  Stop by the [#bitcoin-dev][] IRC chatroom
+and tell us what documentation you want to write.*
+
+## Bitcoin.org Bandwidth Sharing Guide
+
+The [Bitcoin.org bandwidth sharing guide][bandwidth sharing guide]
+currently provides instructions for how to install Bitcoin Core on
+multiple operating systems, configure it to automatically start at boot,
+and manually open port 8333 so it accepts incoming connections.
+
+To contribute, you can [edit the guide][edit bandwidth sharing
+guide] using the same GitHub web interface as described in the
+previous section.
+
+*Need help getting started? You can [open an issue][] or email Bitcoin.org
+documentation maintainer {{site.text.bitcoin_org_docs_maintainer_email_link}}.*
+
+## Bitcoin Wiki
+
+The Bitcoin Wiki uses the popular MediaWiki software, so you may already
+know how to edit it and create new pages. To reduce spam, you need to
+[create an account][wiki create account] and then follow the
+[instructions to enable editing][wiki enable editing].
+
+Current documentation can be found in the [Bitcoin Core documentation
+category][wiki bitcoin core documentation].  If you create a new page,
+be sure to add it to the [Bitcoin Core documentation template][wiki
+template bitcoin core documentation] and then add the following code to
+the very bottom of the page:
+
+    {% raw %}{{Bitcoin Core documentation}}{% endraw %}
+
+Adding the line above to a page will also add that page to the Bitcoin
+Core documentation category.
+
+*Need help getting started?  Stop by the [#bitcoin-wiki][] IRC chatroom and
+tell us what documentation you want to write.*
+
+## Bitcoin.org RPC/REST API Reference
+
+The [Bitcoin.org developer reference][devref] contains over 100 printed
+pages worth of documentation for the Bitcoin Core RPC and REST
+interfaces, which are mainly used by Bitcoin Core command line users and
+developers of apps depending on Bitcoin Core.
+
+To contribute RPC edits, the easiest way is to:
+
+1. Go to the [Bitcoin.org developer documentation main page][developer documentation].
+
+2. Search for the RPC you want to edit.
+
+3. Under the subheading for the RPC, click the Edit link.
+
+To create new RPC/REST documentation or edit the REST documentation:
+
+1. Follow [these instructions][open a pull request] to clone the Bitcoin.org repository.
+
+2. RPC files are in the `_includes/ref/bitcoin-core/rpcs` directory.
+
+    REST files are in the `_includes/ref/bitcoin-core/rest` directory.
+
+    New files need to be added to the list in `en/developer-reference.md`
+
+*Need help getting started? You can [open an issue][] or email
+Bitcoin.org documentation maintainer {{site.text.bitcoin_org_docs_maintainer_email_link}}.*
