+# Contributing
+
+## Overview
+
+This documents explains the processes and practices recommended for contributing enhancements to
+the OSM VCA Integrator charm.
+
+- If you would like to chat with us about your use-cases or proposed implementation, you can reach
+ us at [Canonical Mattermost public channel](https://chat.charmhub.io/charmhub/channels/charm-dev)
+ or [Discourse](https://discourse.charmhub.io/).
+- Familiarising yourself with the [Charmed Operator Framework](https://juju.is/docs/sdk) library
+ will help you a lot when working on new features or bug fixes.
+- All enhancements require review before being merged. Code review typically examines
+ - code quality
+ - test coverage
+ - user experience for Juju administrators this charm.
+- Please help us out in ensuring easy to review branches by rebasing your pull request branch onto
+ the `main` branch. This also avoids merge commits and creates a linear Git commit history.
+
+## Developing
+
+You can use the environments created by `tox` for development:
+
+```shell
+tox --notest -e unit
+source .tox/unit/bin/activate
+```
+
+### Testing
+
+```shell
+tox -e fmt # update your code according to linting rules
+tox -e lint # code style
+tox -e unit # unit tests
+tox -e integration # integration tests
+tox # runs 'lint' and 'unit' environments
+```
+
+## Build charm
+
+Build the charm in this git repository using:
+
+```shell
+charmcraft pack
+```
+
+### Deploy
+
+```bash
+# Create a model
+juju add-model test-osm-vca-integrator
+# Enable DEBUG logging
+juju model-config logging-config="<root>=INFO;unit=DEBUG"
+# Deploy the charm
+juju deploy ./osm-vca-integrator_ubuntu-20.04-amd64.charm
+```

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,

+"""VCA Library.
+
+VCA stands for VNF Configuration and Abstraction, and is one of the core components
+of OSM. The Juju Controller is in charged of this role.
+
+This [library](https://juju.is/docs/sdk/libraries) implements both sides of the
+`vca` [interface](https://juju.is/docs/sdk/relations).
+
+The *provider* side of this interface is implemented by the
+[osm-vca-integrator Charmed Operator](https://charmhub.io/osm-vca-integrator).
+
+helps to integrate with the
+vca-integrator charm, which provides data needed to the OSM components that need
+to talk to the VCA, and
+
+Any Charmed OSM component that *requires* to talk to the VCA should implement
+the *requirer* side of this interface.
+
+In a nutshell using this library to implement a Charmed Operator *requiring* VCA data
+would look like
+
+```
+$ charmcraft fetch-lib charms.osm_vca_integrator.v0.vca
+```
+
+`metadata.yaml`:
+
+```
+requires:
+ vca:
+ interface: osm-vca
+```
+
+`src/charm.py`:
+
+```
+from charms.osm_vca_integrator.v0.vca import VcaData, VcaIntegratorEvents, VcaRequires
+from ops.charm import CharmBase
