 # libnitrokey
 libnitrokey is a project to communicate with Nitrokey Pro and Storage devices in a clean and easy manner. Written in C++14, testable with `py.test` and `Catch` frameworks, with C API, Python access (through CFFI and C API, in future with Pybind11).

-## Compilation
+## Build
 libnitrokey uses CMake as its main build system. As a secondary option it offers building through Qt's qMake.
+
+### Docker Isolated Build
+
+To run a docker isolated build it suffices to run the helper command:
+
+```bash
+# build docker image, and execute the build
+$ make docker-build-all
+```
+
+Currently, Ubuntu 20.04 is used as a build base. Results will be placed in the `./build/` directory.
+
 ### Qt
 A Qt's .pro project file is provided for direct compilation and for inclusion to other projects.
 Using it directly is not recommended due to lack of dependencies check and not implemented library versioning.

 **Warning!** Before you run unittests please change both your Admin and User PINs on your Nitrostick to defaults (`12345678` and `123456` respectively), or change the values in tests source code. If you do not change them, the tests might lock your device temporarily. If it's too late already, you can reset your Nitrokey using instructions from [homepage](https://www.nitrokey.com/de/documentation/how-reset-nitrokey).

+
+Here are Python tests helper calls:

+# For Nitrokey Pro
+$ make tests-pro
+# For Nitrokey Storage
+$ make tests-storage

 ## Python tests
 libnitrokey has a great suite of tests written in Python 3 under the path: [unittest/test_*.py](https://github.com/Nitrokey/libnitrokey/tree/master/unittest): 
 * `test_pro.py` - contains tests of OTP, Password Safe and PIN control functionality. Could be run on both Pro and Storage devices.

 # Known issues / tasks
-* Currently only one device can be connected at a time (experimental work could be found in `wip-multiple_devices` branch),
-* C++ API needs some reorganization to C++ objects (instead of pointers to byte arrays). This will be also preparing for integration with Pybind11,
