-
-Thank you for your interest in contributing to GrimAC. This document outlines the guidelines for
-making pull
-requests to the project. *We're usually pretty lenient with pull requests, but this guide will help
-make the process go more smoothly.*
-
-### Acceptable Pull Requests
-
-**Bug fixes** and **new features** are welcome. However, some things like heuristic-based checks
-will **not** be accepted.
-
-### Pull Request Guidelines
-
-- Ensure any changes are compatible with
-  the [supported environments](https://github.com/GrimAnticheat/Grim/wiki/Supported-environments).
-- Create a new branch for your feature or fix when forking the repository.
-- Write clear and descriptive commit messages.
-- Reference related issues in your pull request description if applicable.
-- Add code comments for complex logic or significant changes.
-- Try to keep your code clean and avoid duplication.
-- Thoroughly test your changes before submitting your pull request.
-
-### Development Notes
-
-- GrimAC is built using [Gradle](https://gradle.org/).
-- Java 21 is currently required to build the project, but it is not required to run it.
-
-### Questions & Support

-  see [Supported-environments](https://github.com/GrimAnticheat/Grim/wiki/Supported-environments).*
-- If you use Geyser, place Floodgate on the backend server so grim can exempt bedrock players. Grim
-  cannot access the Floodgate API if it is on the proxy.
-- If you use ViaVersion, it should be on the backend server as movement is highly dependent on
-  client version.

-/**
- * BuildConfig provides access to user-defined build flags that control how a Grim
- * build is assembled. These flags are resolved once at configuration time using
- * [init], and are then exposed as fast, memoized values.
- *
- * Flags can be defined in three ways:
- *
- *   ① JVM system properties  (-Dflag=value)
- *   ② Gradle project properties  (-Pflag=value or in gradle.properties)
- *   ③ Environment variables  (FLAG=value)
- *
- * You can use these to enable/disable features like shading, relocation, or release mode.
- *
- * Examples:
- *
- * Using Gradle -P properties:
- * ```
- * ./gradlew build -PshadePE=true -Prelocate=false -Prelease=true
- * ```
- *
- * Using environment variables:
- * ```
- * SHADE_PE=true RELOCATE_JAR=false RELEASE=true ./gradlew build
- * ```
- *
- * Using JVM system properties:
- * ```
- * ./gradlew build -DshadePE=true -Drelease=true
- * ```
- *
- * @property shadePE  If true, shades PacketEvents into the jar. Default: true.
- * @property relocate If true, relocates shaded dependencies to avoid conflicts. Default: true.
- * @property release  If true, omits commit hash and modifiers from version string. Default: false.
- * @property mavenLocalOverride If true, will make artifacts in mavenLocal() will be used instead of their remote counterparts for this build. Default: false
