Quick start

1. Install Python
2. Install the prerequisites: pip install -r requirements.txt
3. Install the Google Cloud SDK
4. Run gcloud init and create a new project
5. Enable the Document AI API: gcloud services enable documentai.googleapis.com
6. Setup application default authentication, run: gcloud auth application-default login

2. Use pyenv to install the latest version of Python 3 for example, to install Python version 3.10.1, run: pyenv install 3.10.1
3. Create a Python virtual environment with the installed version of Python 3, for example, to create a Python 3.10.1 virtual environment called docai-annotator, run: pyenv virtualenv 3.10.1 docai-annotator
4. Clone this repo and cd to the root of the repo
5. Configure pyenv to use the virtual python environment we created earlier when in this repo: pyenv local docai-annotator
6. Install the prerequisites: pip install -r requirements.txt
