# How to contribute components?
|
||||
|
||||
As of Langflow 1.0 alpha, new components are added as objects of the [CustomComponent](https://github.com/langflow-ai/langflow/blob/dev/src/backend/base/langflow/interface/custom/custom_component/custom_component.py) class and any dependencies are added to the [pyproject.toml](https://github.com/langflow-ai/langflow/blob/dev/pyproject.toml#L27) file.
|
||||
|
||||
## Add an example component
|
||||
|
||||
You have a new document loader called **MyCustomEmbedding** and it would look awesome in Langflow.

|
||||
|
||||
1. Write your loader as an object of the [CustomComponent](https://github.com/langflow-ai/langflow/blob/dev/src/backend/base/langflow/interface/custom/custom_component/custom_component.py) class. You'll create a new class, `MyCustomEmbeddingComponent`, that will inherit from `CustomComponent` and override the base class's methods.

|
||||
2. Define optional attributes like `display_name`, `description`, and `documentation` to provide information about your custom component.
|
||||
3. Implement the `build_config` method to define the configuration options for your custom component.
|
||||
4. Implement the `build` method to define the logic for taking input parameters specified in the `build_config` method and returning the desired output.
|
||||
5. Add the code to the [/components/document_loaders](https://github.com/langflow-ai/langflow/tree/dev/src/backend/base/langflow/components) folder.
|
||||
6. Add the dependency to [/document_loaders/\_\_init\_\_.py](https://github.com/langflow-ai/langflow/blob/dev/src/backend/base/langflow/components/documentloaders/__init__.py) as `from .MyCustomEmbedding import MyCustomEmbeddingComponent`.

6. Add the dependency to [/document_loaders/\_\_init\_\_.py](https://github.com/langflow-ai/langflow/blob/dev/src/backend/base/langflow/components/documentloaders/__init__.py) as `from .MyCustomEmbedding import MyCustomDocumentLoader`.
|
||||
7. Add any new dependencies to the outer [pyproject.toml](https://github.com/langflow-ai/langflow/blob/dev/pyproject.toml#L27) file.
|
||||
8. Submit documentation for your component. For this example, you'd submit documentation to the [loaders page](https://github.com/langflow-ai/langflow/blob/dev/docs/docs/components/loaders.mdx).
|
||||
8. Submit your changes as a pull request. The Langflow team will have a look, suggest changes, and add your component to Langflow.
|
||||
|
||||
|
||||
## User Sharing
|
||||
|
||||
You might want to share and test your custom component with others, but don't need it merged into the main source code.
|
||||
|
||||
If so, you can share your component on the Langflow store.
|
||||
|
||||
1. [Register at the Langflow store](https://www.langflow.store/login/).
|
||||
2. Undergo pre-validation before receiving an API key.
|
||||
3. To deploy your amazing component directly to the Langflow store, without it being merged into the main source code, navigate to your flow, and then click **Share**.
|
||||
The share window appears:
|
||||
|
||||
<ZoomableImage
|
||||
alt="Docusaurus themed image"
|
||||
sources={{
|
||||
light: "img/add-component-to-store.png",
|
||||
dark: "img/add-component-to-store.png",
|
||||
}}
|
||||
style={{ width: "50%", margin: "20px auto" }}
|
||||
/>
|
||||
|
||||
5. Choose whether you want to flow to be public or private.
|
||||
You can also **Export** your flow as a JSON file from this window.
|
||||
When you're ready to share the flow, click **Share Flow**.
|
||||
You should see a **Flow shared successfully** popup.
|
||||
6. To confirm, navigate to the **Langflow Store** and filter results by **Created By Me**. You should see your new flow on the **Langflow Store**.
