 ## Installation
 
-### Binary releases
 
-NOTE: The Binary releases are not being maintained. Suggest building from Sources instead.
-
-If you want to use `htm.core` from Python, the easiest method is to install from [PyPI](https://test.pypi.org/project/htm.core/)
-  - Note: to install from `pip` you'll need Python 3.7 only(does not work with older or newer versions)
-
-```
-python -m pip install -i https://test.pypi.org/simple/ htm.core
-```
-Note: to run all examples with visualizations, install including extra requirements:
-`pip install -i https://test.pypi.org/simple/ htm.core[examples]`
-
-If you intend to use `htm.core` as a library that provides you Python \& C++ HTM, 
-you can use our [binary releases](https://github.com/htm-community/htm.core/releases).
