+# VBHelper
+
+Application to interact with the Vital series, VB, VH, VBC and VBBE.
+
+## Current state of the project
+
+Right now the project is still under development, and until further notice, any database updates will result in having to erase application data.
+
+This document will be updated once the application does not need any more database resets.
+
+## Features
+
+As of now, the project allows you to read characters, view characters stats, and send them back to your watch. 
+
+You can also apply items to the characters read, such as special missions, or change timers, and store characters in the storage section.
+
+You also earn new items every time an item such as a special mission (VB only) or a character completes an in-app adventure mission.
+
+App also comes with a dex that will update every time a new character is added, and allows you to see evolution requirements and current adventure stage in the watch.
+
+## How to set up
+
+1. Download the latest version for VB Arena APK from a trustworthy source. If your download is a standalone APK, continue to step 2. Otherwise, if your download is an XAPK, do the following:
+
+    1. Using your phone file manager, rename the XAPK file to ZIP, and extract its contents. You can also do this with any other device, such as Windows, macOS and Linux. 
+
+    2. Once the files are extracted, look for an APK called `com.bandai.vitalbraceletarena.apk`. Copy it somewhere else, you will need it.
+
+2. Install an APK release for VB Helper. You will find the releases [here](http://github.com/nacabaro/vbhelper/releases). Download the latest release and install its APK.
+
+    Note, in the current stage of the project, you will have to delete the old application from your device. If the app keeps crashing after installing, clear application data and storage.
+
+3. Import secrets in the app. These secrets will allow the app to talk to the watch. On the main screen, click on the gear icon, then `Import secrets`.
+    
+    You will be prompted to choose a file. Choose the APK file that was previously obtained.
+
+4. Import cards. Due to copyright laws, we cannot offer the characters and sprites themselves in the application. In order to import the cards do the following.
+
+    1. Using your own DiM/BEm cards, dump the cards to your device. You can get an in-depth tutorial in [here](http://mrblinky.net/digimon/vb/dimcardtool/dimcardtool.html). You can download the dump tool from [here](http://mrblinky.net/digimon/vb/dimcardtool/)
+
+    2. Once installed the tool and drivers, open the tool, connect your DiM/BEm reader hardware to yout computer and click on Read card.
+
+    3. Transfer the resulting file to your mobile device. You can put them anywhere, as long as they are accessible. My recommendation is to put them under a folder called `Cards` in your `Internal storage` or `SD Card`
+
+    4. In the app, click on import card. Next choose the BIN file corresponding to the card you want to import.
+
+    **Note: if you do not import the card, whenever you attempt to read a character from th watch, the character you read will get deleted.** 
+
+5. App will now be ready to be used.
+
+## Planned features
+
+- Online battles, undegoing development by `lightheel`.
+
+- VitalWear compatibility, undergoing development by `cfogrady`.
+
+- Support for multiple languages, not yet started.
+
+- Database backup/restore.
+
+## Credits
+
+- `cyanic` for helping us understand more about the VB connection protocol.
+
+- `cfogrady` for making both [`VB-DIM-Reader`](https://github.com/cfogrady/VB-DIM-Reader) and [`lib-vb-nfc`](https://github.com/cfogrady/lib-vb-nfc)
+
+- `lightheel` for working on the online component in the application, both server and battle client.
+
+- `shvstrz` for the app icon.
