# In this script you are going to find the process of releasing bittensor.
#
# This script needs:
#   - An existing VERSION file
#   - Version in VERSION file is not a git tag already
#
# This process will generate:
#   - Tag in Github repo: https://github.com/opentensor/bittensor/tags
#   - Release in Github: https://github.com/opentensor/bittensor/releases
#   - New entry in CHANGELOG.md file
#   - Python wheel in pypi: https://pypi.org/project/bittensor/
#   - Docker image in dockerhub: https://hub.docker.com/r/opentensorfdn/bittensor/tags (TODO)
