Mail-in-a-Box is an open source community project about working, as a group, to empower ourselves and others to have control over our own digital communications. Just as we hope to increase technological diversity on the Internet through decentralization, we also believe that diverse viewpoints and voices among our community members foster innovation and creative solutions to the challenges we face.
We are committed to providing a safe, welcoming, and harrassment-free space for collaboration, for everyone, without regard to age, disability, economic situation, ethnicity, gender identity and expression, language fluency, level of knowledge or experience, nationality, personal appearance, race, religion, sexual identity and orientation, or any other attribute. Community comes first. This policy supersedes all other project goals.

Community comes first. This policy supersedes all other project goals.
The maintainers of Mail-in-a-Box share the dual responsibility of leading by example and enforcing these policies as necessary to maintain an open and welcoming environment. All community members should be excellent to each other.

# 1. Enter your server instance (or on the Vagrant image)

# 3. Run `sudo ./setup/nextcloud.sh`
# 4. Ensure the installation completes. If any hashes mismatch, correct them.
# 5. Enter nextcloud web, run following tests:
# 5.1 You still can create, edit and delete contacts
# 5.2 You still can create, edit and delete calendar events
# 5.3 You still can create, edit and delete users
# 5.4 Go to Administration > Logs and ensure no new errors are shown
