-What is Bitcoin?
-----------------
-
-Bitcoin is an experimental digital currency that enables instant payments to
-anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate
-with no central authority: managing transactions and issuing money are carried
-out collectively by the network. Bitcoin Core is the name of open source
-software which enables the use of this currency.
+This is the integration and staging tree for the Elements blockchain platform,
+a collection of feature experiments and extensions to the Bitcoin protocol.
+This platform enables anyone to build their own businesses or networks
+pegged to Bitcoin as a sidechain or run as a standalone blockchain with arbitrary asset tokens.
 
-For more information, as well as an immediately useable, binary version of
-the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the
-[original whitepaper](https://bitcoincore.org/bitcoin.pdf).
+Confidential Assets
+----------------
+The latest feature in the Elements blockchain platform is Confidential Assets,
+the ability to issue multiple assets on a blockchain where asset identifiers
+and amounts are blinded yet auditable through the use of applied cryptography.

+Features of the Elements blockchain platform
+----------------
 
-Development Process
--------------------
+Compared to Bitcoin itself, it adds the following features:
+ * [Confidential Assets][asset-issuance]
+ * [Confidential Transactions][confidential-transactions]
+ * [Federated Two-Way Peg][federated-peg]
+ * [Signed Blocks][signed-blocks]
+ * [Additional opcodes][opcodes]
 
-The `master` branch is regularly built and tested, but is not guaranteed to be
-completely stable. [Tags](https://github.com/bitcoin/bitcoin/tags) are created
-regularly to indicate new official, stable release versions of Bitcoin Core.
+Previous elements that have been integrated into Bitcoin:
+ * Segregated Witness
+ * Relative Lock Time
 
-The contribution workflow is described in [CONTRIBUTING.md](CONTRIBUTING.md).
+Elements deferred for additional research and standardization:
+ * [Schnorr Signatures][schnorr-signatures]
 
-Testing

-Testing and code review is the bottleneck for development; we get more pull
-requests than we can review and test on short notice. Please be patient and help out by testing
-other people's pull requests, and remember this is a security-critical project where any mistake might cost people
-lots of money.

-Developers are strongly encouraged to write [unit tests](src/test/README.md) for new code, and to
-submit new unit tests for old code. Unit tests can be compiled and run
-(assuming they weren't disabled in configure) with: `make check`. Further details on running
-and extending unit tests can be found in [/src/test/README.md](/src/test/README.md).
+What is the Elements Project?
+-----------------
+Elements is an open source, sidechain-capable blockchain platform. It also allows experiments to more rapidly bring technical innovation to the Bitcoin ecosystem.
 
-There are also [regression and integration tests](/test), written
-in Python, that are run automatically on the build server.
-These tests can be run (if the [test dependencies](/test) are installed) with: `test/functional/test_runner.py`
+Learn more on the [Elements Project website](https://elementsproject.org)
 
-The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
-
-### Manual Quality Assurance (QA) Testing
-
-Changes should be tested by somebody other than the developer who wrote the
-code. This is especially important for large or high-risk changes. It is useful
-to add a test plan to the pull request description if testing the changes is
-not straightforward.
-
-Translations
-------------
-
-Changes to translations as well as new translations can be submitted to
-[Bitcoin Core's Transifex page](https://www.transifex.com/projects/p/bitcoin/).
-
-Translations are periodically pulled from Transifex and merged into the git repository. See the
-[translation process](doc/translation_process.md) for details on how this works.
-
-**Important**: We do not accept translation changes as GitHub pull requests because the next
-pull from Transifex would automatically overwrite them again.
-
-Translators should also subscribe to the [mailing list](https://groups.google.com/forum/#!forum/bitcoin-translators).
