From my initial 5 minutes of getting setup with an existing install, it's all fairly easy.

# Requirements

  - lz4
  - zstd

# Building

  git clone https://github.com/hydradatabase/hydra
  cd hydra/columnar
  ./configure
  make
  make install

# Install

  CREATE EXTENSION IF NOT EXISTS columnar;

The actual extension docs are at https://docs.hydra.so/concepts/using-hydra-columnar
