+# Setting up a dev environment
+
+## Prerequisites
+
+Mastodon development requires the following:
+
+- Ruby 3.0
+- Ruby gems:
+  - `bundler`
+  - `irb`
+  - `foreman`
+- NodeJS v18 (LTS)
+- NPM packages:
+  - `yarn`
+- Postgres
+- Redis
+
+### macOS
+
+First, make sure you have Homebrew installed. Follow the instructions at [brew.sh](https://brew.sh).
+
+Run the following to install all necessary packages:
+```
+brew install ruby@3.0 foreman node yarn postgresql redis
+```
+
+Ruby 3.0 is **keg-only** by default. Follow the instructions in the **Caveat** to add it to your path.
+
+### Linux
+
+We will assume that you know how to locate the correct packages for your distro. That said, some distros package `bundler` and `irb` separately. Make sure that you also install these.
+
+On Arch, you will need:
+- `ruby`
+- `ruby-bundler`
+- `ruby-irb`
+- `ruby-foreman`
+- `redis`
+- `postgresql`
+- `yarn`
+- `gmp`
+- `libidn`
+
+### Windows
+
+Unfortunately, none of the authors use Windows. Contributions welcome!
+
+## Database
+
+In the root of this repository, go through the following script:
+```sh
+# Create a folder for local data
+mkdir -p data
+
+# Set up a local database
+pg_ctl -D data/postgres initdb -o '-U mastodon --auth-host=trust'
+
+# Use the data/postgres folder for the DB connection unix socket
+#
+# If you don't know what that means, it's just a way for Mastodon to communicate
+# with a database on the same machine efficiently.
+#
+# See: https://manpages.ubuntu.com/manpages/jammy/man7/unix.7.html
+echo 'unix_socket_directories = .' >> data/postgres/postgresql.conf
+
+# Start the database
+pg_ctl -D data/postgres start --silent
+```
+
+## Redis
+
+In the root of this repository, run the following:
+```sh
+# Create a folder for redis data
+mkdir -p data/redis
+
+# Start Redis
+redis-server ./redis-dev.conf
+
+# [Optional] Stop Redis
+# kill "$(cat ./data/redis/redis-dev.pid)"
+```
+
+## Ruby
+
+```sh
+export RAILS_ENV=development
+
+# Bundle installs all Ruby gems globally by default, which might cause problems.
+bundle config set --local path 'vendor/bundle'
+
+# [Apple Silicon] If using macOS on Apple Silicon, run the following:
+# bundle config build.idn-ruby -- --with-idn-dir="$(brew --prefix libidn)"
+
+# Install dependencies using bundle (Ruby) and yarn (JS)
+bundle install
+yarn install
+
+# Setup the database using the pre-defined Rake task
+#
+# Rake is a command runner for Ruby projects. The `bundle exec` ensures that
+# we use the version of Rake that this project requires.
+bundle exec rake db:setup
+
+# [Optional] If that fails, run the following and try again:
+# bundle exec rake db:reset
+```
+
+## Running Mastodon
+
+1. Run `export RAILS_ENV=development NODE_ENV=development`.
+    - Put these in your shell's .rc, or a script you can source if you want to skip this step in the future.
+2. Run `bundle exec rake assets:precompile`.
+    - If this explodes, complaining about `Hash`, you'll need to `export NODE_OPTIONS=--openssl-legacy-provider`.
+    - After doing this, you will need to run `bundle exec rake assets:clobber` and then re-run `bundle exec rake assets:precompile`.
+3. Run `foreman start`
+
+# Updates/Troubleshooting
+
+## RubyVM/DebugInspector Issues
+
+Still unable to fix. Circumvent by removing `better_errors` and `binding_of_caller` from Gemfile.
+
+Happy to troubleshoot with someone better with Ruby than us >_<'/.
+
+## Webpack Issues
+
+If Webpack compalins about being unable to find some assets or locales:
+
+Try:
+1. `rm -rf node_modules`
+2. `yarn install`
+
+If this doesn't help, try:
+1. `yarn add webpack`
+2. `git restore package.json yarn.lock`
+3. `yarn install`
+
+Then re-run `foreman start`. No. We have no idea why this worked.
+
+# Need Help?

+If the above instructions don't work, please contact @Rin here, or @tammy@social.treehouse.systems.
