+Windows Binary Builds
+=====================
+
+These scripts can be used for cross-compilation of Windows Electrum executables from Linux/Wine.
+Produced binaries are deterministic, so you should be able to generate binaries that match the official releases. 
+
+
+Usage:
+
+
+1. Install the following dependencies:
+
+ - dirmngr
+ - gpg
+ - 7Zip
+ - Wine (>= v2)
+
+
+For example:
+
+
+```
+$ sudo apt-get install wine-development dirmngr gnupg2 p7zip-full
+$ wine --version
+ wine-2.0 (Debian 2.0-3+b2)
+```
+
+or
+
+```
+$ pacman -S wine gnupg
+$ wine --version
+ wine-2.21
+```
+
+2. Make sure `/opt` is writable by the current user.
+3. Run `build.sh`.
+4. The generated binaries are in `./dist`.
