+Installation
+=========================
+
+The easiest way to install the Python API and the slsDetectorPackage is using conda. But other
+methods are also available. 
+
+---------------------
+Install using conda
+---------------------
+If you don't have it installed get the latest version of `Miniconda`_
+
+.. _Miniconda: https://conda.io/miniconda.html
+
+::
+
+    wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
+    sh Miniconda3-latest-Linux-x86_64.sh
+
+
+Install sls_detector and sls_detector_lib using:
+
+::
+
+    #Add conda channels
+    conda config --add channels conda-forge
+    conda config --add channels slsdetectorgroup
+
+    #Install latest version
+    conda install sls_detector
+
+    #Install specific version
+    conda install sls_detector=3.0.1
+
+------------------------------
+Local build using conda-build
+------------------------------
+
+Needs the `sls_detector_lib`_ installed  in order to automatically find headers
+and shared libraries. Make sure that the branch of sls_detector matches the lib 
+version installed. 
+
+.. _sls_detector_lib: https://github.com/slsdetectorgroup/sls_detector_lib
+
+::
+
+    #Clone source code
+    git clone https://github.com/slsdetectorgroup/sls_detector.git
+
+    #Checkout the branch needed
+    git checkout 3.0.1
+
+    #Build and install the local version
+    conda-build sls_detector
+    conda install --use-local sls_detector
+
+
+-----------------------
+Developer build
+-----------------------
+
+IF you if you are developing and are making constant changes to the code it's a bit cumbersome
+to build with conda and install. Then an easier way is to build the C/C++ parts in the package
+directory and temporary add this to the path
+
+::
+
+    #in path/to/sls_detector
+    python setup.py build_ext --inplace
+
+Then in your Python script
+
+::
+
+    import sys
+    sys.path.append('/path/to/sls_detector')
+    from sls_detector import Detector
+
+
+
+--------------
+Prerequisites
+--------------
+
+All dependencies are manged trough conda but for a stand alone build you would need
+
+ * gcc 4.8+
+ * Qwt 6
+ * Qt 4.8
+ * numpy
+ * slsDetectorPackage
