## High-Level Overview
- **Core**: Serves as the main infrastructure. All extensions and providers have `openbb-core` as a dependency.
- **Extensions**: Utility packages that leverage Core's infrastructure. Each extension is its own package.
- **Providers**: Utility packages extending functionality to different providers, where each provider is its own package.
> This page assumes that the OpenBB GitHub repo has been cloned.
## Core Dependency Management
### Installation
:::warning
Do not run these commands in an already-installed OpenBB Platform environment. Do not run both `pip` and `poetry`.
:::
- **pip**: `pip install -e OpenBBTerminal/openbb_platform/platform/core`
or
- **poetry**: `poetry install OpenBBTerminal/openbb_platform/platform/core`
### Using Poetry
Ensure you're in a fresh conda environment before adjusting dependencies.
- **Add a Dependency**: `poetry add `
- **Update Dependencies**:
- All: `poetry update`
- Specific: `poetry update `
- **Remove a Dependency**: `poetry remove `
## Core and Extensions
### Dev Installation
For development setup, use the provided script to install all extensions and their dependencies:
- `python dev_install.py [-e|--extras]`
> **Note**: If developing an extension, avoid installing all extensions to prevent unnecessary overhead.
### Dependency Management with Poetry
- **Add Platform Extension**: `poetry add openbb-extension-name [--dev]`
- **Resolve Conflicts**: Adjust versions in `pyproject.toml` if notified by Poetry.
- **Lock Dependencies**: `poetry lock`
- **Update Platform**: `poetry update openbb-platform`
- **Documentation**: Maintain `pyproject.toml` and `poetry.lock` for a clear record of dependencies.
