-=====================================

+[![Build Status](https://travis-ci.org/lbryio/lbrycrd.svg?branch=master)](https://travis-ci.org/lbryio/lbrycrd)
 
-https://bitcoincore.org
+LBRYcrd uses a blockchain similar to bitcoin's to implement an index and payment system for content on the LBRY network. It is a fork of bitcoin core. In addition to the libraries used by bitcoin, LBRYcrd also uses icu4c.
 
-What is Bitcoin?
+Please read the [lbry.tech overview](https://lbry.tech/overview) for a general understanding of the LBRY pieces. From there you could read the [LBRY spec](https://spec.lbry.com/) for specifics on the data in the blockchain. 
-----------------
 
-Bitcoin is an experimental digital currency that enables instant payments to
+## Installation
-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.
 
-For more information, as well as an immediately useable, binary version of
+Latest binaries are available from https://github.com/lbryio/lbrycrd/releases. There is no installation procedure; the CLI binaries will run as-is and will have any uncommon dependencies statically linked into the binary. The QT GUI is not supported. LBRYcrd is distributed as a collection of executable files; traditional installers are not provided. 
-the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the
-[original whitepaper](https://bitcoincore.org/bitcoin.pdf).
 
-License
+## Usage
--------
 
-Bitcoin Core is released under the terms of the MIT license. See [COPYING](COPYING) for more
+The `lbrycrdd` executable will start a LBRYcrd node and connect you to the LBRYcrd network. Use the `lbrycrd-cli` executable
-information or see https://opensource.org/licenses/MIT.
+to interact with lbrycrdd through the command line. Command-line help for both executables are available through
+the "--help" flag (e.g. `lbrycrdd --help`). Examples:
 
-Development Process
+#### Examples:
--------------------
+
+Run `./lbrycrdd -server -daemon` to start lbrycrdd in the background.
+
+Run `./lbrycrd-cli getinfo` to check for some basic information about your LBRYcrd node.
+
+Run `./lbrycrd-cli help` to get a list of all commands that you can run. To get help on specific commands run `./lbrycrd-cli [command_name] help`
+
+Test locally:
+```
+./lbrycrdd -server -regtest -txindex  # run this in its own window
+./lbrycrd-cli -regtest generate 120   # mine 20 spendable coins
+./lbrycrd-cli -regtest claimname my_name deadbeef 1 # hold a name claim with 1 coin
+./lbrycrd-cli -regtest generate 1     # get that claim into the block
+./lbrycrd-cli -regtest listnameclaims # show owned claims
+./lbrycrd-cli -regtest getclaimsforname my_name # show claims under that name
+./lbrycrd-cli -regtest stop           # kill lbrycrdd
+rm -fr ~/.lbrycrd/regtest/            # destroy regtest data
+```
+For further understanding of a "regtest" setup, see the local stack setup instructions here: https://lbry.tech/resources/regtest-setup
+
+The CLI help is also browsable online at https://lbry.tech/api/blockchain
+
+#### Data directory:
+
+Lbrycrdd will use the below default data directories (changeable with -datadir):
+
+```
+Windows:  %APPDATA%\lbrycrd
+Mac:      ~/Library/Application Support/lbrycrd
+Unix:     ~/.lbrycrd
+```
+The data directory contains various things such as your default wallet (wallet.dat), debug logs (debug.log), and blockchain data. You can optionally create a configuration file lbrycrd.conf in the default data directory which will be used by default when running lbrycrdd.
+
+For a list of configuration parameters, run `./lbrycrdd --help`. Below is a sample lbrycrd.conf to enable JSON RPC server on lbrycrdd.
+
+```
+rpcuser=lbry
+rpcpassword=xyz123456790
+daemon=1
+server=1
+txindex=1
+```
+
+## Running from Source
+The easiest way to compile is to utilize the Docker image that contains the necessary compilers: lbry/build_lbrycrd. This will allow you to reproduce the build as made on our build servers. I this sample we map a local lbrycrd folder and a local ccache folder inside the image:
+```
+git clone https://github.com/lbryio/lbrycrd.git
+cd lbrycrd
+docker run -v "$(pwd):/lbrycrd" --rm -v "${HOME}/ccache:/ccache" -w /lbrycrd -e CCACHE_DIR=/ccache lbry/build_lbrycrd packaging/build_linux_64bit.sh
+```
+Some examples of compiling directly:
+#### Ubuntu with pulled static dependencies:
+```
+sudo apt install build-essential git libtool autotools-dev automake pkg-config bsdmainutils curl ca-certificates
+git clone https://github.com/lbryio/lbrycrd.git
+cd lbrycrd
+./packaging/build_linux_64bit.sh
+./src/test/test_lbrycrd
+
+```
+Other Linux distros would be similar. The build shell script is fairly trivial; take a peek at its contents.
+#### Ubuntu with local shared dependencies:
+Note: using untested dependencies may lead to conflicting results.
+```
+sudo add-apt-repository ppa:bitcoin/bitcoin
+sudo apt-get update
+sudo apt-get install libdb4.8-dev libdb4.8++-dev libicu-dev libssl-dev libevent-dev \ 
+                     build-essential git libtool autotools-dev automake pkg-config bsdmainutils curl ca-certificates \
+                     libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev
+                    
+# optionally include libminiupnpc-dev libzmq3-dev
+
+git clone https://github.com/lbryio/lbrycrd.git
+cd lbrycrd
+./autogen.sh
+./configure --enable-static --disable-shared --with-pic --without-gui CXXFLAGS="-O3 -march=native"
+make -j$(nproc)
+./src/lbrycrdd -server ...
+
+```
+#### MacOS (cross-compiled):
+```
+sudo apt-get install clang llvm git libtool autotools-dev automake pkg-config bsdmainutils curl ca-certificates \
+                     libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev
+                    
+git clone https://github.com/lbryio/lbrycrd.git
+cd lbrycrd
+# download MacOS SDK from your favorite source
+mkdir depends/SDKs
+tar ... extract SDK to depends/SDKs/MacOSX10.11.sdk
+./packaging/build_darwin_64bit.sh
+
+```
+Look in packaging/build_darwin_64bit.sh for further understanding.
+#### MacOS with local shared dependencies:
+```
+brew install boost berkeley-db@4 icu4c libevent
+# fix conflict with gawk pulled first:
+brew reinstall readline
+brew reinstall gawk
+
+git clone https://github.com/lbryio/lbrycrd.git
+cd lbrycrd/depends
+make NO_QT=1
+cd ..
+./autogen.sh
+CONFIG_SITE=$(pwd)/depends/x86_64-apple-darwin15.6.0/share/config.site ./configure --enable-static --disable-shared --with-pic --without-gui --enable-reduce-exports CXXFLAGS=-O2
+make -j$(sysctl -n hw.ncpu)
+
+```
+#### Windows (cross-compiled):
+Compiling on MS Windows (outside of WSL) is not supported. The Windows build is cross-compiled from Linux like so:
+```
+sudo apt-get install build-essential git libtool autotools-dev automake pkg-config bsdmainutils curl ca-certificates \
+                     g++-mingw-w64-x86-64 mingw-w64-x86-64-dev
+                     
+update-alternatives --set x86_64-w64-mingw32-g++ /usr/bin/x86_64-w64-mingw32-g++-posix
+                    
+git clone https://github.com/lbryio/lbrycrd.git
+cd lbrycrd
+./packaging/build_windows_64bit.sh
+
+```
+
+If you encounter any errors, please check `doc/build-*.md` for further instructions. If you're still stuck, [create an issue](https://github.com/lbryio/lbrycrd/issues/new) with the output of that command, your system info, and any other information you think might be helpful. The scripts in the packaging folder are simple and will grant extra light on the build process as needed.

+We follow the same coding guidelines as documented by Bitcoin Core, see [here](/doc/developer-notes.md). To run an automated code formatting check, try:
+`git diff -U0 master -- '*.h' '*.cpp' | ./contrib/devtools/clang-format-diff.py -p1`. This will check any commits not on master for proper code formatting.
+We try to avoid altering parts of the code that is inherited from Bitcoin Core unless absolutely necessary. This will make it easier to merge changes from Bitcoin Core. If commits are expected not to be merged upstream (i.e. we broke up a commit from Bitcoin Core in order to use a single feature in it), the commit message must contain the string "NOT FOR UPSTREAM MERGE".

-Testing
--------
