Aspect	Open Source	Enterprise
Governance	Maintainers, community consensus, meritocracy-based influence	Empowered teams, lightweight oversight, guardrails over gates
Code Review	Public PRs, async reviews from global contributors, emphasis on transparency	Small PRs, fast feedback loops, pair/mob programming as alternative
Documentation	README-driven, contributor guides essential, public wikis	Living documentation, lightweight ADRs, docs as code
Branching Strategy	Fork-and-PR model, contributors work in personal forks	Trunk-based development, short-lived feature branches (< 1 day)
Communication	Public channels (GitHub issues, Discord, mailing lists)	Co-located teams (in space /and or time), minimal ceremony
Release Cadence	Varies widely, often semver-based, maintainer-driven	Continuous delivery, deploy on merge, feature flags for controlled rollout
Testing	CI on PRs, community-contributed

# By default, Docker containers run as the root user. This is bad because:
#   1) You're more likely to modify up settings that you shouldn't be
#   2) If an attacker gets access to your container - well, that's bad if they're root.
# Here's how you can run change a Docker container to run as a non-root user

## CREATE APP USER ##

# Create the home directory for the new app user.
