 A [PCAPdroid](https://github.com/emanuele-f/PCAPdroid) addon which uses [mitmproxy](https://mitmproxy.org) to decrypt the TLS/SSL connections and show the decrypted data in the app.
 
 The addon uses the open source framework [chaquopy](https://chaquo.com/chaquopy) to bundle and run python modules. The native python modules are pre-built and installed from the chaquopy [pip repository](https://chaquo.com/pypi-7.0).
+
+# Build
+
+Install Python 3.8 and ensure to pull the submodules with `git submodules update --init`. Then build with gradle as usual.
