-Introduction
-============
-
-Collective Knowledge is our "swiss knife" for open, collaborative and reproducible experimentation.
-CK is a small, portable and customizable research SDK to
-* share artifacts as reusable and indexable Python components with unified JSON API and meta information (programs, benchmarks, data sets, tools, predictive models, etc) - see [Artifact Evaluation website](http://ctuning.org/ae/submission.html); 
-* automate detection or installation of all software dependencies on Linux, Windows, MacOS, Android while enabling co-existence of different versions (compilers, benchmarks, libraries, tools) for a given experimental workflow across diverse Linux, Windows and Android based platforms via [CK cross-platform customizable package and environment manager](https://github.com/ctuning/ck/wiki/Portable-workflows);
-* quickly prototype experimental workflows from shared components (such as customizable and multi-objective autotuning for DSL, OpenCL, CUDA, MPI, OpenMP and compiler flags) across diverse hardware and software ([CK repo](https://github.com/ctuning/ck-autotuning));
-* crowdsource experiments across diverse hardware and workloads provided by volunteers and validate ideas or report unexpected behavior and bugs ([CK repo](https://github.com/ctuning/ck-crowdtuning));
-* reuse and collaborative improve JSON description of all existing platforms from IoT to supercomputers ([CK repo](https://github.com/ctuning/ck-crowdtuning-platforms));
-* abstract access to continuously evolving software and hardware stack ([CK repo](https://github.com/ctuning/ck-env));
-* automate, reproduce and crowdsource empirical experiments using CK JSON-based web services ([live repo](http://cKnowledge.org/repo));
-* unify access to predictive analytics (scikit-learn, R, DNN, etc) via unified JSON API and CK web services ([CK repo](https://github.com/ctuning/ck-analytics));
-* enable reproducible and interactive articles ([CK repo](https://github.com/ctuning/ck-web)).

-Acknowledgments
-===============
-
-CK development is coordinated by the [cTuning foundation](http://cTuning.org) (non-profit research organization)
-and [dividiti](http://dividiti.com). We would like to thank the [EU TETRACOM 609491 Coordination Action](http://tetracom.eu) 
-for initial funding, Microsoft for sponsoring hosting of a CK public
-repository in the Azure cloud, and all our partners for continuing support.
-We are also extremely grateful to all volunteers for their valuable feedback and contributions.
-
-Minimal installation
-====================
-
-The minimal installation requires:
-
-* Python 2.7 or 3.3+ (limitation is mainly due to unitests)
-* Python PIP (if you would like to install CK via PIP)
-* Git command line client.
-
-On Ubuntu, you can install these dependencies via
-
-```
-$ apt-get install -y python python-pip git
-```
-
-On Windows, you can download and install these tools from the following sites:
-
-* Git: https://git-for-windows.github.io
-* Minimal Python: https://www.python.org/downloads/windows
-* Anaconda scientific Python with all packages: https://www.continuum.io/downloads#_windows
-
-You can now install stable CK version via PIP simply as following
-(you may need to prefix it with "sudo" on Linux):
-
-```
-$ pip install ck
-```
-
-Alternatively, you can install development CK version in your local user space
-via GIT as following:
-
-```
- $ git clone https://github.com/ctuning/ck.git ck
-```
-and then add CK to PATH on Linux as following:
-```
- $ export PATH=$PWD/ck/bin:$PATH
-```
-or on Windows as following:
-
-```
- $ set PATH={CURRENT PATH}\ck\bin;%PATH%
-```
-
-Further installation details can be found [here](https://github.com/ctuning/ck/wiki/Getting-started-guide#Quick_CK_installation).
-
-Trying CK using Docker image
-============================
-
-If you would like to try CK without installing it, 
-you can run the following Docker image:
-
-```
- $ docker run -it ctuning/ck
-```
-
-Also note that we added Docker automation to CK 
-(to help evaluate artifacts at the conferences, share interactive 
-and reproducible articles or crowdsource experiments for example). 
-
-Please check 'ck-docker' repository at GitHub:
-
-```
- $ ck show repo:ck-docker
-```
-
-You can download and view one of our CK-based interactive and reproducible articles as following:
-```
- $ ck pull repo:ck-docker
- $ ck run docker:ck-interactive-article --browser (--sudo)
-```
-
-See the list of other CK-related Docker images [here](https://hub.docker.com/u/ctuning).
-
-However note that the main idea behind CK is to be able to rebuild user experimental workflows
-natively, take advantage of the latest software environment and hardware,
-and enable open research via collaborative reuse and agile improvement 
-of all shared artifacts and workflows.
-
-Practical use cases
-===================
-
-See the [list of real use cases](http://cKnowledge.org/use_cases.html) 
-by the [growing CK community](http://cKnowledge.org/partners.html).
