 # Build Instructions
 
-Build instructions are available on [the website](https://polymc.org/wiki/development/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
+```

 ## Forking/Redistributing/Custom builds policy
 
 We don't care what you do with your fork/custom build 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 PolyMC and is not endorsed by or affiliated with the PolyMC project (https://polymc.org).
-- Go through [CMakeLists.txt](CMakeLists.txt) and change PolyMC'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).
