 Getting Started
 ---------------
 Build instructions and additional documentation are available in the
 [wiki](https://github.com/bitshares/bitshares-core/wiki).

     sudo apt-get update
     sudo apt-get install autoconf cmake make automake libtool git libboost-all-dev libssl-dev g++ libcurl4-openssl-dev
 
-To build after all dependencies are installed:

     cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .
     make
 
-**NOTE:** BitShares requires an [OpenSSL](https://www.openssl.org/) version in the 1.0.x series. OpenSSL 1.1.0 and newer are NOT supported. If your system OpenSSL version is newer, then you will need to manually provide an older version of OpenSSL and specify it to CMake using `-DOPENSSL_INCLUDE_DIR`, `-DOPENSSL_SSL_LIBRARY`, and `-DOPENSSL_CRYPTO_LIBRARY`.
