+# What is Xpatch
+
+Xpatch is a jar tool which is used to repackage the apk file. Then, the new apk can load any Xposed modules installed in the android system.  
+
+This is a way to use Xposed modules without root your device. 
+
+It is easy way to modify one app using xposed module. And any apps changed by Xpatch can load every modules downloaded in the [Xposed Module Repository](https://repo.xposed.info/).
+# Benefits
+1. Use xposed modules without your device;
+2. Modify any apps without root your device.
+
+# How to use
+1. Download the latest jar file from the [release page](https://github.com/WindySha/Xpatch/releases);
+2. Run this command in the Windows/Mac console:
+```
+$ java -jar ../../xpatch.jar  ../../source.apk
+```
+Then,  a new apk named `source-xposed-signed.apk` in the same folder as `source.apk`.
+
+# More commands
+1. You can specify the output apk path by add `-o` parameter, eg:
+```
+$ java -jar ../../xpatch.jar   ../../source.apk -o  ../../dst.apk
+```
+2. Show all the building new apk logs, just add `-l`, eg:
+```
+$ java -jar ../../xpatch.jar   ../../source.apk -l
+```
+3. Not delete the build files, just add `-k`, eg:
+```
+$ java -jar ../../xpatch.jar   ../../source.apk -k
+```
+4. After the version 1.2, craching app signature verifying is added, if you won't need the function, just add '-c', eg:
+```
+$ java -jar ../../xpatch.jar   ../../source.apk -c
+```
+5. More command details can be found when no parameter is added, eg:
+```
+$ java -jar ../../xpatch.jar 
+```
+
+
+# Todo list
+1. Support packaging the xposed modules into the source apk;
+2. Support loading so library in the xposed modules;
+3. Crach apk protections.
+
+# Issues
+1. If the apk dex files are protected,  dex2jar can not effect on the dexs, then this tool will not work;
+2. The hook framework is using [whale](https://github.com/asLody/whale); this framework is not very stable, some hooks may fail;
+3. Do not support Davlik VM;
+4. Do not support resource hook;
+
