+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+

+#### WebFinger
 
 In Mastodon, users are identified by a `username` and `domain` pair (e.g., `Gargron@mastodon.social`).
 This is used both for discovery and for unambiguously mentioning users across the fediverse. Furthermore, this is part of Mastodon's database design from its very beginnings.
 
 As a result, Mastodon requires that each ActivityPub actor uniquely maps back to an `acct:` URI that can be resolved via WebFinger.

+### MacOS
+
+To set up **MacOS** for native development, complete the following steps:
+
+- Install the latest stable Ruby version (use a Ruby version manager for easy installation and management of Ruby versions)
+- Run `brew install postgresql@14`
+- Run `brew install redis`
+- Run `brew install imagemagick`
+- Run `brew install libidn`
+- Install Foreman or a similar tool (such as [overmind](https://github.com/DarthSim/overmind)) to handle multiple process launching.
+- Navigate to Mastodon's root directory and run `brew install nvm` then `nvm use` to use the version from .nvmrc
+- Run `corepack enable && corepack prepare`
+- Run `bundle exec rails db:setup` (optionally prepend `RAILS_ENV=development` to target the dev environment)
+- Finally, run `overmind start -f Procfile.dev`

+### Docker
+
+For development with **Docker**, complete the following steps:
+
+- Install Docker Desktop
+- Run `docker compose -f .devcontainer/docker-compose.yml up -d`
+- Run `docker compose -f .devcontainer/docker-compose.yml exec app .devcontainer/post-create.sh`
+- Finally, run `docker compose -f .devcontainer/docker-compose.yml exec app foreman start -f Procfile.dev`
