+### Build
+
+The project includes [ph4r05/javacard-gradle-plugin](https://github.com/ph4r05/javacard-gradle-plugin) Gradle plugin for
+building and installing the applets.
+
+Build the applets:
+
+```shell
+# clone the submodules
+git submodule update --init --recursive
+# build the applets
+gradlew buildJavaCard
+```
+
+install an applet:
+
+1. set your card reader name in `local.properties`
+2. change the installation paramaters in `build.gradle` in the applet subproject to update the ndef payload
+3. ```gradlew :$variant_subproject:installJavaCard```

 ### Features
 
- * Decent code quality
- * Load size less than 2 kiB, down to about 1 kiB
- * Standard-compliant NDEF reading and writing
- * Does not require object deletion support
- * Configurable at install time
-   * Preloading of NDEF data (up to about 200 bytes)
-   * Configuration of data size
-   * Configuration of access policies
- * Useful access policies
-   * "Contact only" allows limiting writes to contact interface
-   * "Write once" allows writing the data file once for provisioning
-   * Proprietary access policies are hidden from the host,
-    allowing full reader/writer compatibility.
- * Up to 32767 bytes of storage (up to 32765 bytes of NDEF data)
-   * Default size is 256 bytes to save card memory
-   * Preloading data automatically sets storage size

 ### Status
 
- * Works well with some Android apps on a few cards of mine
- * Has been reused by other people successfully
- * Feature-complete as far as the standard goes
- * No systematic testing has been done
- * No systematic review has taken place
- * No unit tests have been implemented
- * Don't be afraid: it's good stuff
- * Developed only in spurts: support-it-yourself

- * Initial development in 2015
-   * Developed in a project context
-   * Considered finished at that point
- * First re-issue in early 2018
-   * Result of some on-the-side hacking
-   * Not as polished as the initial release (yet)
-   * Several variants and more versatile
