+Code Signing
+============
+
+Electrum Windows builds are signed with a Microsoft Authenticode™ code signing
+certificate in addition to the GPG-based signatures.
+
+The advantage of using Authenticode is that Electrum users won't receive a
+Windows SmartScreen warning when starting it.
+
+The release signing procedure involves a signer (the holder of the
+certificate/key) and one or multiple trusted verifiers:
+
+
+| Signer | Verifier |
+|-----------------------------------------------------------|-----------------------------------|
+| Build .exe files using `build.sh` | |
+| | Build .exe files using `build.sh` |
+| | Sign .exe files using `gpg -b` |
+| | Send signatures to signer |
+| Place signatures as `$filename.$builder.asc` in `./dist` | |
+| Run `./sign.sh` | |
+
+
+`sign.sh` will check if the signatures match the signer's files. This ensures that the signer's
+build environment is not compromised and that the binaries can be reproduced by anyone.
