 # Build Instructions
 
-Full build instructions will be available on [the website](https://prismlauncher.org/wiki/development/build-instructions/).
-
-If you would like to contribute or fix an issue with the Build instructions you will be able to do so [here](https://github.com/PrismLauncher/website/blob/master/src/wiki/development/build-instructions.md).
-
-## Getting the source
-
-Clone the source code using git, and grab all the submodules. This is generic for all platforms you want to build on.
-```
-git clone --recursive https://github.com/PrismLauncher/PrismLauncher
-cd PrismLauncher
-```
-
-## Linux
-
-This guide will mostly mention dependant packages by their Debian naming and commands are done by a user in the sudoers file.
-### Dependencies
-
-- A C++ compiler capable of building C++17 code (can be found in the package `build-essential`).
-- Qt Development tools 5.12 or newer (on Debian 11 or Debian-based distributions, `qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools libqt5core5a libqt5network5 libqt5gui5`).
-- `cmake` 3.15 or newer.
-- `extra-cmake-modules`.
-- zlib (`zlib1g-dev` on Debian 11 or Debian-based distributions).
-- Java Development Kit (Java JDK) (`openjdk-17-jdk` on Debian 11 or Debian-based distributions).
-- Mesa GL headers (`libgl1-mesa-dev` on Debian 11 or Debian-based distributions).
-- (Optional) `scdoc` to generate man pages.
-
-In conclusion, to check if all you need is installed (including optional):
-
-```
-sudo apt install build-essential qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools libqt5core5a libqt5network5 libqt5gui5 cmake extra-cmake-modules zlib1g-dev openjdk-17-jdk libgl1-mesa-dev scdoc
-```
-
-### Compiling
-#### Building and installing on the system
-This is usually the suggested way to build the client.
-
-```
-cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="/usr" -DENABLE_LTO=ON
-cmake --build build -j$(nproc)
-sudo cmake --install build
-```
-
-#### Building a portable binary
-
-```
-cmake -S . -B build -DCMAKE_INSTALL_PREFIX=install
-cmake --build build -j$(nproc)
-cmake --install build
-cmake --install build --component portable
-```
-
+Full build instructions are available on [the website](https://prismlauncher.org/wiki/development/build-instructions/).

+We use [automated backports](https://github.com/PrismLauncher/PrismLauncher/blob/develop/.github/workflows/backport.yml) to merge specific contributions from develop into `release` branches.
+
+This is done when pull requests are merged and have labels such as `backport release-7.x` - which should be added along with the milestone for the release.

+
+## Forking/Redistributing/Custom builds policy
+
+You are free to fork, redistribute and provide custom builds as long as you follow the terms of the [license](LICENSE) (this is a legal responsibility), and if you made code changes rather than just packaging a custom build, please do the following as a basic courtesy:
+
+- Make it clear that your fork is not Prism Launcher and is not endorsed by or affiliated with the Prism Launcher project (<https://prismlauncher.org>).
+- Go through [CMakeLists.txt](CMakeLists.txt) and change Prism Launcher's API keys to your own or set them to empty strings (`""`) to disable them (this way the program will still compile but the functionality requiring those keys will be disabled).
+
+If you have any questions or want any clarification on the above conditions please make an issue and ask us.
+
+If you are just building Prism Launcher for your distribution, please make sure to set the `Launcher_BUILD_PLATFORM` to a slug representing your distribution. Examples are `archlinux`, `fedora` and `nixpkgs`.
+
+Note that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions:
+
+- [Microsoft Identity Platform Terms of Use](https://docs.microsoft.com/en-us/legal/microsoft-identity-platform/terms-of-use)
+- [CurseForge 3rd Party API Terms and Conditions](https://support.curseforge.com/en/support/solutions/articles/9000207405-curse-forge-3rd-party-api-terms-and-conditions)
+
+If you do not agree with these terms and conditions, then remove the associated API keys from the [CMakeLists.txt](CMakeLists.txt) file by setting them to an empty string (`""`).
