1. Install Visual Studio >= 2017 with CMake support.
2. Download and install Boost prebuilt binaries https://sourceforge.net/projects/boost/files/boost-binaries/1.68.0/boost_1_68_0-msvc-14.1-64.exe, also add BOOST_ROOT to the Environment Variables.
3. Download and install OpenSSL prebuilt binaries https://slproweb.com/products/Win32OpenSSL.html (Win64 OpenSSL v1.1.0h for example) and add OPENSSL_ROOT_DIR to the Environment Variables.
4. Download and install QT 5.11 http://master.qt.io/new_archive/qt/5.11/5.11.0/qt-opensource-windows-x86-5.11.0.exe and add QT5_ROOT_DIR to the Environment Variables (usually it looks like .../5.11.0/msvc2017_64), also add QML_IMPORT_PATH (it should look like %QT5_ROOT_DIR%\qml). BTW disabling system antivirus on Windows makes QT installing process much faster.
5. Add .../qt511/5.11.1/msvc2017_64/bin and .../boost_1_68_0/lib64-msvc-14.1 to the System Path.
6. Open project folder in Visual Studio, select your target (Release-x64 for example, if you downloaded 64bit Boost and OpenSSL) and select CMake -> Build All.
7. Go to CMake -> Cache -> Open Cache Folder -> hds (you'll find binaries in hds/..., wallet/..., ui/..., explorer/... subfolders).

Please read carefully the points below

1. After finishing your build you'll find the the hds-node binary (node) in the hds/hds folder, hds-wallet (cli wallet) in the hds/wallet folder and HdsWallet (GUI wallet) in the hds/ui folder.

2. You need to clone hds sources before building

git clone https://github.com/hadescoincom/hds-core.git

The command above checks out the latest master branch where all the development happens. Usually it is not what you want to build. Choose an appropriate branch here and check out it after you have the main repository cloned. For example the command below checks out the Double Doppler 4.0 release branch

cd hds-core
git checkout double_doppler_4.0RC

3. By default instructions produce masternet builds (development version, development blockchain). To be able to build testnet (testing) or mainnet (real-world blockchain) you need to edit the hds/CMakeLists.txt file lines 151-157. Uncomment (remove the '#' sign) respective definitions.

# uncomment next line for testnet
#set(HDS_TESTNET TRUE)
# uncomment next line for mainnet
#set(HDS_MAINNET TRUE)

# uncomment next line for swap mainnet
#set(SWAP_MAINNET TRUE)

4. Server instructions result only in a valid build and enable you running all the CLI tools. They are not intended to ensure that you would be able to run the UI. Desktop build instructions include additional steps to ensure that the UI can be launched.

5. At the moment building the UI can take a lot of time (a few hours) due to the bug in QT: QTBUG-27936. To skip building the UI pass -DHDS_NO_QT_UI_WALLET=On to cmake. You can also omit all Qt5 dependencies in this case.

Instructions below are valid for a clean default Ubuntu 18.04.03 Desktop LTS install. If your're building on an aged system please check that steps 1, 2 & 4 do not overwrite/conflict with more recent versions of cmake and boost that might have been installed before. You can omit cmake/boost installation if you already have more recent versions.
