+## About
+**jadx** - Dex to Java decompiler
+
+### Build
+jadx uses [gradle](http://www.gradle.org/) for build:
+
+    git clone https://github.com/skylot/jadx.git
+    cd jadx
+    ./gradlew build
+    
+(on windows, use `gradlew.bat` instead of `./gradlew`)
+
+Scripts for run jadx will be placed in `build/install/jadx/bin`
+and also packed to `build/distributions/jadx-<version>.zip`
+
+### Run
+Run **jadx** on itself:
+
+    cd build/install/jadx/
+    bin/jadx -d out lib/jadx-*.jar
+
+### Usage
+```
+jadx [options] <input files> (.dex, .apk, .jar or .class)
+options:
+ -d, --output-dir     - output directory
+ -j, --threads-count  - processing threads count
+ -f, --fallback       - make simple dump (using goto instead of 'if', 'for', etc)
