+JungfrauDataFile
+==================
+
+JungfrauDataFile is a class to read the .dat files that are produced by Aldo's receiver. 
+It is mostly used for calibration. 
+
+The structure of the file is:
+
+* JungfrauDataHeader
+* Binary data (256x256, 256x1024 or 512x1024)
+* JungfrauDataHeader
+* ...
+
+There is no metadata indicating number of frames or the size of the image, but this
+will be infered by this reader.

+****************
+Tests
+****************
+
+We test the code both from the C++ and Python API. By default only tests that does not require image data is run. 
+
+C++
+~~~~~~~~~~~~~~~~~~
+
+.. code-block:: bash
+
+    mkdir build
+    cd build
+    cmake .. -DAARE_TESTS=ON
+    make -j 4
+
+    export AARE_TEST_DATA=/path/to/test/data
+    ./run_test [.files] #or using ctest, [.files] is the option to include tests needing data
+
+
+
+Python
+~~~~~~~~~~~~~~~~~~
+
+.. code-block:: bash
+
+    #From the root dir of the library
+    python -m pytest python/tests --files # passing --files will run the tests needing data
+
+
+
+Getting the test data
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. attention ::
+
+    The tests needing the test data are not run by default. To make the data available, you need to set the environment variable
+    AARE_TEST_DATA to the path of the test data directory. Then pass either [.files] for the C++ tests or --files for Python
+
+The image files needed for the test are large and are not included in the repository. They are stored
+using GIT LFS in a separate repository. To get the test data, you need to clone the repository.
+To do this, you need to have GIT LFS installed. You can find instructions on how to install it here: https://git-lfs.github.com/
+Once you have GIT LFS installed, you can clone the repository like any normal repo using:
+
+.. code-block:: bash
+    
+    git clone https://gitea.psi.ch/detectors/aare-test-data.git
