docker/README.md

+### Customized manylinux images for opencv-python
+
+This folder includes Dockerfiles for extending both ``i686`` and ``x86_64`` manylinux images.
+
+The extended images were created to be able to build OpenCV in reasonable time with Travis.
+
+These images have been built locally because the process takes over an hour with modern i7 processor. The images are hosted at https://quay.io/user/skvark.
+
+The images have following extra software installed:
+
+- Qt 4.8.7
+- Cmake 3.9.0
+- FFmpeg with libvpx
+- libjpeg-turbo 1.5.3
+- Some missing headers included from more recent Linux to be able to enable V4L / V4L2 support in OpenCV
