+# VBHelper
+
+## Developer Setup
+
+1. Clone vb-nfc-reader (https://github.com/cfogrady/lib-vb-nfc)
+2. Run vb-nfc-reader/publishToMavenLocal gradle task in the lib-vb-nfc project.
+3. Clone vb-dim-reader (https://github.com/cfogrady/vb-dim-reader)
+4. Run publishToMavenLocal gradle task in the vb-dim-reader project.
+5. Create res/values/keys.xml within the app module.
+6. Populate with:
+```
+<?xml version="1.0" encoding="utf-8"?>
+<resources>
+    <string name="password1">beHmacKey1</string>
+    <string name="password2">beHmacKey2</string>
+    <string name="decryptionKey">aesKey</string>
+    <integer-array name="substitutionArray">
+        <item>0</item>
+        <item>1</item>
+        <item>2</item>
+        <item>3</item>
+        <item>4</item>
+        <item>5</item>

+        <item>14</item>
+        <item>15</item>
+    </integer-array>
+</resources>
+```
+7. Replace the values in the keys.xml file with those extracted from the original app.
+8. Run
