-# Installation
-
-Head over to the releases page and grab the latest binary. https://github.com/adityapk00/zec-qt-wallet/releases
-
-### Linux
-Extract and run the binary.
-```
-tar -xvf zec-qt-wallet-v0.4.3.tar.gz
-./zec-qt-wallet-v0.4.3/zec-qt-wallet
-```
-
-### Windows
-Unzip the release binary and double click on zec-qt-wallet to start.
-
-### macOS
-Double-click on the .dmg file to open it, and drag zec-qt-wallet on to the Applications link to install.
-
-## zcashd
-zec-qt-wallet needs a Zcash node running zcashd. If you already have a zcashd node running, zec-qt-wallet will connect to it. 
-
-If you don't have one, zec-qt-wallet will start its embedded zcashd node. 
-
-Additionally, if this is the first time you're running zec-qt-wallet or a zcashd daemon, zec-qt-wallet will download the zcash params (~1.7 GB) and configure `zcash.conf` for you. 
-
-Pass `--no-embedded` to disable the embedded zcashd and force zec-qt-wallet to connect to an external node.
-
-## Compiling from source
-zec-qt-wallet is written in C++ 14, and can be compiled with g++/clang++/visual c++. It also depends on Qt5, which you can get from [here](https://www.qt.io/download)
-
-See detailed build instructions [on the wiki](https://github.com/ZcashFoundation/zec-qt-wallet/wiki/Compiling-from-source-code)
-
-### Building on Linux
-
-```
-git clone https://github.com/adityapk00/zec-qt-wallet.git
-cd zec-qt-wallet
-/path/to/qt5/bin/qmake zec-qt-wallet.pro CONFIG+=debug
-make -j$(nproc)
-
-./zec-qt-wallet
-```
-
-### Building on Windows
-You need Visual Studio 2017 (The free C++ Community Edition works just fine). 
-
-From the VS Tools command prompt
-```
-git clone https://github.com/adityapk00/zec-qt-wallet.git
-cd zec-qt-wallet
-c:\Qt5\bin\qmake.exe zec-qt-wallet.pro -spec win32-msvc CONFIG+=debug
-nmake
-
-debug\zec-qt-wallet.exe
-```
-
-To create the Visual Studio project files so you can compile and run from Visual Studio:
-```
-c:\Qt5\bin\qmake.exe zec-qt-wallet.pro -tp vc CONFIG+=debug
-```
-
-### Building on macOS
-You need to install the Xcode app or the Xcode command line tools first, and then install Qt. 
-
-```
-git clone https://github.com/adityapk00/zec-qt-wallet.git
-cd zec-qt-wallet
-/path/to/qt5/bin/qmake zec-qt-wallet.pro CONFIG+=debug
-make
-
-./zec-qt-wallet.app/Contents/MacOS/zec-qt-wallet
-```

+If you are on Debian/Ubuntu, please download the `.deb` package and install it.
+```
+sudo dpkg -i linux-deb-zec-qt-wallet-v0.5.0.deb
+sudo apt install -f
+```
+
+Or you can download and run the binaries directly.
+```
+tar -xvf zec-qt-wallet-v0.5.0.tar.gz
+./zec-qt-wallet-v0.5.0/zec-qt-wallet
+```
+
+### Windows
+Download and run the .msi installer and follow the prompts. Alternately, you can download the release binary, unzip it and double click on zec-qt-wallet to start.
+
+### macOS
+Double-click on the .dmg file to open it, and drag zec-qt-wallet on to the Applications link to install.
