+# Huggingface
+
+Versatile Data Kit (VDK) plugin for integrating with Huggingface as both a data source and a target.
+This plugin allows you to ingest data payloads into a Huggingface repository and makes it easier to work with datasets stored in Huggingface.
+
+
+## Usage
+
+```
+pip install vdk-huggingface
+```
+
+The functionality adds new ingestion method "huggingface" which can be used like that:
+
+```python
+job_input.send_object_for_ingestion(data, method="huggingface")
+```
+
+
+### Configuration
+
+(`vdk config-help` is useful command to browse all config options of your installation of vdk)
+
+| Name                | Description                                                                 | (example)  Value        |
+|---------------------|-----------------------------------------------------------------------------|-------------------------|
+| HUGGINGFACE_TOKEN   | HuggingFace API token for authentication. Get one from HuggingFace Settings | ""                      |
+| HUGGINGFACE_REPO_ID | HuggingFace Dataset repository ID                                           | "username/test-dataset" |
+
+
+
+### Build and testing
+
+```
+pip install -r requirements.txt
+pip install -e .
+pytest
+```
+
+In VDK repo [../build-plugin.sh](https://github.com/vmware/versatile-data-kit/tree/main/projects/vdk-plugins/build-plugin.sh) script can be used also.
+
+
+#### Note about the CICD:
+
+.plugin-ci.yaml is needed only for plugins part of [Versatile Data Kit Plugin repo](https://github.com/vmware/versatile-data-kit/tree/main/projects/vdk-plugins).
+
+The CI/CD is separated in two stages, a build stage and a release stage.
+The build stage is made up of a few jobs, all which inherit from the same
+job configuration and only differ in the Python version they use (3.7, 3.8, 3.9 and 3.10).
+They run according to rules, which are ordered in a way such that changes to a
+plugin's directory trigger the plugin CI, but changes to a different plugin does not.
