Quick Use

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

  1. Clone and set up:
git clone https://github.com/calesthio/OpenMontage.git
cd OpenMontage
make setup

  1. Copy .env.example to .env and add your API keys (OpenAI, ElevenLabs, etc.)

  2. Describe the video you want and let OpenMontage produce it:

python produce.py "Create a 60-second animated explainer about how MCP servers work"
