+# Measurement Kit JNI Libs
+
+This repository contains Measurement Kit Java native interface (JNI). It
+also contains the code to generate Measurement Kit JNI libs.
+
+The `Makefile` file allows you to cross-compile JNI libs suitable for being
+used by Android applications.
+
+To see all the available targets, just type:
+
+```
+make
+```
+
+To generate a tarball containing the Java files and the corresponding
+compiled libraries, type:
+
+```
+make dist
+```
+
+This will download the latest Measurement Kit binaries from GitHub, verify
+them with GnuPG, cross-compile the JNI code and statically link it with the
+downloaded binaries, package a tarball suitable for distribution.
+
+The version number of the tarball will be the version downloaded from
+GitHub, plus the abbreviated reference of the current HEAD.
+
+A Unix environment is assumed. You need to have the following executables
+in your PATH:
+
+- git
+- wget
+- ndk-build
+- gpg2
+
+Git, wget, and gpg2 could be installed using your distributions package
+manager. As regards ndk-build, [there are instructions to install it inside
+Measurement Kit repository](https://github.com/measurement-kit/measurement-kit/tree/master/mobile/android#installing-the-ndk).
