+Pengujian Enkripsi
+------------------
+
+Ini adalah ranah bagi yang ingin mengembangkan paket ini. Terlepas dari
+spesifikasi Winpay maka ada pengujian enkripsi, baik dengan *salt* maupun
+tidak. Winpay tanpa salt. Karena ini sesi development maka *clone* terlebih
+dahulu::
+
+    $ git clone https://git.opensipkd.com/sugiana/winpay-client
+
+Lalu pasang paket yang dibutuhkan::
+
+    $ cd winpay-client
+    $ ~/env/bin/pip install -e .[dev]
+
+Jalankan script pengujian::
+
+    $ cd tests
+    $ ~/env/bin/pytest
+
+Pastikan tidak ada yang gagal. Semoga dipahami.
