 # 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
+```

+# Contributions Guidelines
+
+## Code formatting
+
+Try to follow the existing formatting.
+If there is no existing formatting, you may use `clang-format` with our included `.clang-format` configuration.
+
+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.
+
+## Signing your work
+
+In an effort to ensure that the code you contribute is actually compatible with the licenses in this codebase, we require you to sign-off all your contributions.
+
+This can be done by appending `-s` to your `git commit` call, or by manually appending the following text to your commit message:
+
+```
+<commit message>
+
+Signed-off-by: Author name <Author email>
+```
+
+By signing off your work, you agree to the terms below:
+
+```
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+These terms will be enforced once you create a pull request, and you will be informed automatically if any of your commits aren't signed-off by you.
+
+As a bonus, you can also [cryptographically sign your commits][gh-signing-commits] and enable [vigilant mode][gh-vigilant-mode] on GitHub.
+

-## Building
-
-If you want to build PolyMC yourself, check [Build Instructions](https://polymc.org/wiki/development/build-instructions/) for build instructions.
-
-## Code formatting
-
-Just follow the existing formatting.
-
-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.

+ECMQueryQt
+---------------
+This module can be used to query the installation paths used by Qt.
+
+For Qt5 this uses ``qmake``, and for Qt6 this used ``qtpaths`` (the latter has built-in
+support to query the paths of a target platform when cross-compiling).
+
+This module defines the following function:
+::
+
+    ecm_query_qt(<result_variable> <qt_variable> [TRY])
+
+Passing ``TRY`` will result in the method not making the build fail if the executable
+used for querying has not been found, but instead simply print a warning message and
+return an empty string.
+
+Example usage:
+
+.. code-block:: cmake
+
+    include(ECMQueryQt)
+    ecm_query_qt(bin_dir QT_INSTALL_BINS)
+
+If the call succeeds ``${bin_dir}`` will be set to ``<prefix>/path/to/bin/dir`` (e.g.
+``/usr/lib64/qt/bin/``).
+
+Since: 5.93
