+      Introduce the topic. If this is a not-well-known section of PolyMC, a detailed explanation of the background is recommended.
+      Some example points of discussion:
+       - What specific problems are you facing right now that you're trying to address?
+       - Are there any previous discussions? Link to them and summarize them (don't force your readers to read them though!).

-Build Instructions
-==================
+# Build Instructions
 
-# Contents
+Build instructions are available on [the website](https://polymc.org/wiki/development/build-instructions/).
 
-* [Note](#note)
-* [Getting the source](#source)
-* [Linux](#linux)
-* [Windows](#windows)
-* [macOS](#macos)
-
-
-# Getting the source
-
-Clone the source code using git and grab all the submodules:
-
-```
-git clone https://github.com/PolyMC/PolyMC.git
-git submodule init
-git submodule update
-```
-
-# Linux
-
-Getting the project to build and run on Linux is easy if you use any modern and up-to-date linux distribution.
-
-## Build dependencies
-* A C++ compiler capable of building C++11 code.
-* Qt Development tools 5.6 or newer  (`qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools libqt5core5a libqt5network5 libqt5gui5` on Debian-based system)
-* cmake 3.1 or newer (`cmake` on Debian-based system)
-* zlib (`zlib1g-dev` on Debian-based system)
-* Java JDK (`openjdk-17-jdk`on Debian-based system)
-* GL headers (`libgl1-mesa-dev` on Debian-based system)
-
-### Building a .deb
-
-You need to install the build dependencies first
-
-```
-git clone https://github.com/PolyMC/PolyMC.git
-git submodule init && git submodule update
-cd packages/debian
-./makedeb.sh
-```
-
-If everything works correctly, the .deb will be next to the build script, in `PolyMC/packages/debian`
-
-### Building a .rpm
-
-You don't need to install the build dependencies, as the script will use `dnf` to install them for you.
-
-```
-git clone https://github.com/PolyMC/PolyMC.git
-cd packages/rpm
-./makerpm.sh
-```
-
-If everything works correctly, the .rpm will be next to the build script, in `PolyMC/packages/rpm`
-
-### Building from command line
-You need a source folder, a build folder and an install folder.
-
-```
-# make all the folders
-mkdir ~/PolyMC && cd ~/PolyMC
-mkdir build
-mkdir install
-# clone the complete source
-git clone --recursive https://github.com/PolyMC/PolyMC.git src
-# configure the project
-cd build
-cmake -DCMAKE_INSTALL_PREFIX=../install ../src
-make -j$(nproc) install
-```
-
-You can use IDEs like KDevelop or QtCreator to open the CMake project if you want to work on the code.
-
-### Building & Installing to the System
-This is the preferred method for installation, and is suitable for packages.
-
-```
-git clone --recursive https://github.com/PolyMC/PolyMC.git && cd PolyMC
-
-# configure everything
-cmake -S . -B build \
-	-DCMAKE_BUILD_TYPE=Release \
-    -DCMAKE_INSTALL_PREFIX="/usr" \ # Use "/usr" for packages, otherwise, leave it at the default "/usr/local".
-    -DLauncher_LAYOUT=lin-system
-
-make -j$(nproc) install # Optionally specify DESTDIR for packages (i.e. DESTDIR=${pkgdir})
-```
-
-### Installing Qt using the installer (optional)
-1. Run the Qt installer.
-2. Choose a place to install Qt.
-3. Choose the components you want to install.
-    - You need Qt 5.6.x 64-bit ticked.
-    - You need Tools/Qt Creator ticked.
-    - Other components are selected by default, you can untick them if you don't need them.
-4. Accept the license agreements.
-5. Double check the install details and then click "Install".
-    - Installation can take a very long time, go grab a cup of tea or something and let it work.
-
-### Loading the project in Qt Creator (optional)
-1. Open Qt Creator.
-2. Choose `File->Open File or Project`.
-3. Navigate to the Launcher source folder you cloned and choose CMakeLists.txt.
-4. Read the instructions that just popped up about a build location and choose one.
-5. You should see "Run CMake" in the window.
-    - Make sure that Generator is set to "Unix Generator (Desktop Qt 5.6.x GCC 64bit)".
-    - Hit the "Run CMake" button.
-    - You'll see warnings and it might not be clear that it succeeded until you scroll to the bottom of the window.
-    - Hit "Finish" if CMake ran successfully.
-6. Cross your fingers and press the Run button (bottom left of Qt Creator).
-    - If the project builds successfully it will run and the Launcher window will pop up.
-
-**If this doesn't work for you, let us know on our Discord.**
-
-# Windows
-
-Getting the project to build and run on Windows is easy if you use Qt's IDE, Qt Creator. The project will simply not compile using Microsoft build tools, because that's not something we do. If it does compile, it is by chance only.
-
-## Dependencies
-* [Qt 5.6+ Development tools](http://qt-project.org/downloads) -- Qt Online Installer for Windows
-    - http://download.qt.io/new_archive/qt/5.6/5.6.0/qt-opensource-windows-x86-mingw492-5.6.0.exe
-    - Download the MinGW version (MSVC version does not work).
-* [OpenSSL](https://github.com/IndySockets/OpenSSL-Binaries/tree/master/Archive/) -- Win32 OpenSSL, version 1.0.2g (from 2016)
-    - https://github.com/IndySockets/OpenSSL-Binaries/raw/master/Archive/openssl-1.0.2g-i386-win32.zip
-    - the usual OpenSSL for Windows (http://slproweb.com/products/Win32OpenSSL.html) only provides the newest version of OpenSSL, and we need the 1.0.2g version
-    - **Download the 32-bit version, not 64-bit.**
-    - Microsoft Visual C++ 2008 Redist is required for this, there's a link on the OpenSSL download page above next to the main download.
-    - We use a custom build of OpenSSL that doesn't have this dependency. For normal development, the custom build is not necessary though.
-* [zlib 1.2+](http://gnuwin32.sourceforge.net/packages/zlib.htm) - the Setup is fine
-* [Java JDK 8](https://adoptium.net/releases.html?variant=openjdk8) - Use the MSI installer.
-* [CMake](http://www.cmake.org/cmake/resources/software.html) -- Windows (Win32 Installer)
-
-Ensure that OpenSSL, zlib, Java and CMake are on `PATH`.
-
-## Getting set up
-
-### Installing Qt
-1. Run the Qt installer
-2. Choose a place to install Qt (C:\Qt is the default),
-3. Choose the components you want to install
-    - You need Qt 5.6 (32 bit) ticked,
-    - You need Tools/Qt Creator ticked,
-    - Other components are selected by default, you can untick them if you don't need them.
-4. Accept the license agreements,
-5. Double check the install details and then click "Install"
-    - Installation can take a very long time, go grab a cup of tea or something and let it work.
-
-### Installing OpenSSL
-1. Download .zip file from the link above.
-2. Unzip and add the directory to PATH, so CMake can find it.
-
-### Installing CMake
-1. Run the CMake installer,
-2. It's easiest if you choose to add CMake to the PATH for all users,
-    - If you don't choose to do this, remember where you installed CMake.
-
-### Loading the project
-1. Open Qt Creator,
-2. Choose File->Open File or Project,
-3. Navigate to the Launcher source folder you cloned and choose CMakeLists.txt,
-4. Read the instructions that just popped up about a build location and choose one,
-5. If you chose not to add CMake to the system PATH, tell Qt Creator where you installed it,
-    - Otherwise you can skip this step.
-6. You should see "Run CMake" in the window,
-    - Make sure that Generator is set to "MinGW Generator (Desktop Qt 5.6.x MinGW 32bit)",
-    - Hit the "Run CMake" button,
-    - You'll see warnings and it might not be clear that it succeeded until you scroll to the bottom of the window.
-    - Hit "Finish" if CMake ran successfully.
-7. Cross your fingers and press the Run button (bottom left of Qt Creator)!
-    - If the project builds successfully it will run and the Launcher window will pop up,
-    - Test OpenSSL by making an instance and trying to log in. If Qt Creator couldn't find OpenSSL during the CMake stage, login will fail and you'll get an error.
-
-The following .dlls are needed for the app to run (copy them to build directory if you want to be able to move the build to another pc):
-```
-platforms/qwindows.dll
-libeay32.dll
-libgcc_s_dw2-1.dll
-libssp-0.dll
-libstdc++-6.dll
-libwinpthread-1.dll
-Qt5Core.dll
-Qt5Gui.dll
-Qt5Network.dll
-Qt5Svg.dll
-Qt5Widgets.dll
-Qt5Xml.dll
-ssleay32.dll
-zlib1.dll
-```
-
-**These build instructions worked for me (Drayshak) on a fresh Windows 8 x64 Professional install. If they don't work for you, let us know on our Discord.**
-### Compile from command line on Windows
-1. If you installed Qt with the web installer, there should be a shortcut called `Qt 5.4 for Desktop (MinGW 4.9 32-bit)` in the Start menu on Windows 7 and 10. Best way to find it is to search for it. Do note you cannot just use cmd.exe, you have to use the shortcut, otherwise the proper MinGW software will not be on the PATH.
-2. Once that is open, change into your user directory, and clone PolyMC by doing `git clone --recursive https://github.com/PolyMC/PolyMC.git`, and change directory to the folder you cloned to.
-3. Make a build directory, and change directory to the directory and do `cmake -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=C:\Path\that\makes\sense\for\you`. By default, it will install to C:\Program Files (x86), which you might not want, if you want a local installation. If you want to install it to that directory, make sure to run the command window as administrator.
-3. Do `mingw32-make -jX`, where X is the number of cores your CPU has plus one.
-4. Now to wait for it to compile. This could take some time. Hopefully it compiles properly.
-5. Run the command `mingw32-make install`, and it should install PolyMC, to whatever the `-DCMAKE_INSTALL_PREFIX` was.
-6. In most cases, whenever compiling, the OpenSSL dll's aren't put into the directory to where PolyMC installs, meaning you cannot log in. The best way to fix this is just to do `copy C:\OpenSSL-Win32\*.dll C:\Where\you\installed\PolyMC\to`. This should copy the required OpenSSL dll's to log in.
-
-# macOS
-
-### Install prerequisites:
-- Install XCode Command Line tools
-- Install the official build of CMake (https://cmake.org/download/)
-- Install JDK 8 (https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html)
-- Get Qt 5.6 and install it (https://download.qt.io/new_archive/qt/5.6/5.6.3/)
-
-### XCode Command Line tools
-
-If you don't have XCode CommandLine tools installed, you can install them by using this command in the Terminal App
-
-```bash
-xcode-select --install
-```
-
-### Build
-
-Pick an installation path - this is where the final `.app` will be constructed when you run `make install`. Supply it as the `CMAKE_INSTALL_PREFIX` argument during CMake configuration.
-
-```
-git clone --recursive https://github.com/PolyMC/PolyMC.git
-cd Launcher
-mkdir build
-cd build
-cmake \
- -DCMAKE_C_COMPILER=/usr/bin/clang \
- -DCMAKE_CXX_COMPILER=/usr/bin/clang++ \
- -DCMAKE_BUILD_TYPE=Release \
- -DCMAKE_INSTALL_PREFIX:PATH="$(dirname $PWD)/dist/" \
- -DCMAKE_PREFIX_PATH="/path/to/Qt5.6/" \
- -DQt5_DIR="/path/to/Qt5.6/" \
- -DLauncher_LAYOUT=mac-bundle \
- -DCMAKE_OSX_DEPLOYMENT_TARGET=10.7 \
- ..
-make install
-```
-
-**Note:** The final app bundle may not run due to code signing issues, which
-need to be fixed with `codesign -fs -`.

+# Contributor Covenant Code of Conduct
+This is a modified version of the Contributor Covenant.
+See commit history to see our changes.
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling (antagonistic, inflammatory, insincere behaviour), insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement via email at
+[polymc-enforcement@scrumplex.net](mailto:polymc-enforcement@scrumplex.net) (Email
+address subject to change).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## 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
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.1, available at

 PolyMC is a custom launcher for Minecraft that focuses on predictability, long term stability and simplicity.
 
-This is a **fork** of the MultiMC Launcher and not endorsed by MultiMC. The PolyMC community felt that the maintainer was not acting in the spirit of Free Software so this fork was made. Read "[Why was this fork made?](https://github.com/PolyMC/PolyMC/wiki/FAQ)" on the wiki for more details.

-## Packages
-Several source build packages are available, along with experimental pre-built generic packages.

 <br>
-[![AUR package](https://img.shields.io/aur/version/polymc-git)](https://aur.archlinux.org/packages/polymc-git/)
-- A [Nix](packages/nix/NIX.md) derivation is available in repo.
-- A Gentoo ebuild is available in the [swirl](https://git.swurl.xyz/swirl/ebuilds) overlay, named `games-action/polymc`. Check the README for instructions on how to add the overlay.
-- The Flatpak can be built using [this source](https://github.com/flathub/org.polymc.PolyMC).
-- An RPM package is available on [COPR](https://copr.fedorainfracloud.org/coprs/sentry/polymc/), or can be built by going to the `packages/rpm` directory and running `rpmbuild -bb polymc.spec`.
-- Generic, prebuilt packages (archived by version) can be found [here](https://packages.polymc.org/) ([latest](https://packages.polymc.org/latest)).
-- Last build status: https://jenkins.polymc.org/job/PolyMC/lastBuild/
-- [Linux (AMD64) System](https://packages.polymc.org/latest/lin64-system/lin64-system.tar.zst) ([SHA256](https://packages.polymc.org/latest/lin64-system/lin64-system.tar.zst.sha256)) - this is a generic system package intended to be used as a base for making distro-specific packages.
-- [Windows (32-bit)](https://packages.polymc.org/latest/win32/win32.zip) ([SHA256](https://packages.polymc.org/latest/win32/win32.zip.sha256)) - this is a portable package, you can extract it anywhere and run it. This package needs testing.
-- [Debian (AMD64)](https://packages.polymc.org/latest/deb/polymc-amd64.deb) ([SHA256](https://packages.polymc.org/latest/deb/polymc-amd64.deb.sha256)) - this is intended to be installed with `dpkg -i`. Alternatively, you may build the `.deb` yourself, by going to `packages/debian` and running `./makedeb.sh`.
-- [AppImage (AMD64)](https://packages.polymc.org/latest/appimage/PolyMC-latest-x86_64.AppImage) ([SHA256](https://packages.polymc.org/latest/appimage/PolyMC-latest-x86_64.AppImage.sha256)) - `chmod +x` must be run on this file before usage. This should work on any distribution.
-- MacOS currently does not have any packages. We are still working on setting up MacOS packaging.
 
-## Development
-If you want to contribute to PolyMC you might find it useful to join [#development:polymc.org on Matrix](https://matrix.to/#/#development:polymc.org) or join [our Discord server](https://discord.gg/xq7fxrgtMP), which is bridged with the PolyMC Matrix rooms. Thank you!
+# Installation
 
-### Building
-If you want to build PolyMC yourself, check [BUILD.md](BUILD.md) for build instructions.
+- All downloads and instructions for PolyMC can be found [here](https://polymc.org/download/)
+- Last build status: https://github.com/PolyMC/PolyMC/actions
 
-You can build the flatpak using [this source](https://github.com/flathub/org.polymc.PolyMC).
 
-### Code formatting
-Just follow the existing formatting.
+## Development Builds
 
-In general, in order of importance:
-* Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
-* Prefer readability over dogma.
-* Keep to the existing formatting.
-* Indent with 4 space unless it's in a submodule.
-* Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.
+There are per-commit development builds available [here](https://github.com/PolyMC/PolyMC/actions). These have debug information in the binaries, so their file sizes are relatively larger.
+Portable builds are provided for AppImage on Linux, Windows, and macOS.
