+## Overview
+
+This documents explains the processes and practices recommended for contributing enhancements to
+the Update DB charm.
+
+- Generally, before developing enhancements to this charm, you should consider [opening an issue
+ ](https://github.com/gcalvinos/update-db-operator/issues) explaining your use case.
+- 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/). The primary author of this charm is available on
+ the Mattermost channel as `@davigar15`.
+- 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-update-db
+# Enable DEBUG logging
+juju model-config logging-config="<root>=INFO;unit=DEBUG"
+# Deploy the charm
+juju deploy ./update-db_ubuntu-20.04-amd64.charm \
