-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
- - Wine (>= v2)
-
-
-For example:
-
-
-```
-$ sudo apt-get install wine-development dirmngr gnupg2
-$ sudo ln -sf /usr/bin/wine-development /usr/local/bin/wine
-$ 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`.

+"""Sign releases on github, make/upload ppa to launchpad.net
+
+NOTE on ppa: To build a ppa you may need to install some more packages.
+On ubuntu:
+
+     sudo apt-get install devscripts libssl-dev python3-dev \
+          debhelper python3-setuptools dh-python
+
+NOTE on apk signing: To create a keystore and sign the apk you need to install
+      java-8-openjdk, or java-7-openjdk on older systems.
+
+To create a keystore run the following command:
+
+    mkdir ~/.jks && keytool -genkey -v -keystore ~/.jks/keystore \
+        -alias electrum.z.cash -keyalg RSA -keysize 2048 \
+        -validity 10000
+
+Then it shows a warning about the proprietary format and a command to migrate:
+
+    keytool -importkeystore -srckeystore ~/.jks/keystore \
+            -destkeystore ~/.jks/keystore -deststoretype pkcs12
+
+Manual signing:
+
+    jarsigner -verbose \
+        -tsa http://sha256timestamp.ws.symantec.com/sha256/timestamp \

+        Electrum_Zcash-3.0.6.1-release-unsigned.apk \
+        electrum.z.cash
+
+Zipalign from Android SDK build tools is also required (set path to bin in
+settings file or with key -z). To install:
+
+    wget http://dl.google.com/android/android-sdk_r24-linux.tgz \
+    && tar xzf android-sdk_r24-linux.tgz \
+    && rm android-sdk_r24-linux.tgz \

+        | android-sdk-linux/tools/android update sdk -u -a -t \
+            'tools, platform-tools, build-tools-27.0.3'
+
+Manual zip aligning:
+

+
+About script settings:
+
+Settings is read from options, then config file is read.
+If setting is already set from options, then it value does
+not changes.
+
+Config file can have one repo form or multiple repo form.
+
+In one repo form config settings read from root JSON object.
+Keys are "repo", "keyid", "token", "count", "sign_drafts",
+and others, which is corresponding to program options.
+
+Example:
+
+    {
+        "repo": "value"
+        ...
+    }
+
+In multiple repo form, if root "default_repo" key is set, then code
+try to read "repos" key as list and cycle through it to find suitable
+repo, or if no repo is set before, then "default_repo" is used to match.
+If match found, then that list object is used ad one repo form config.
+
+Example:
+
+    {
+        "default_repo": "value"
+        "repos": [
+            {
+                "repo": "value"
+                ...
