-# falcond - Advanced Linux Gaming Performance Daemon
-
-falcond is a powerful system daemon designed to automatically optimize your Linux gaming experience. It intelligently manages system resources and performance settings on a per-game basis, eliminating the need to manually configure settings for each game.
-
-## Features
-
-- **Automatic Game Detection**: Automatically detects running games and applies optimized settings
-- **Per-Game Profiles**: Customizable profiles for different games
-- **Performance Mode**: Enables system-wide performance optimizations when gaming
-- **3D vcache Management**: Smart management of AMD 3D vcache settings
-- **SCX Scheduler Integration**: Dynamically pick a scheduler that is best for the specific game
-- **Proton Compatibility**: Full support for Steam Proton games, with a global profile for excellent game coverage
-- **Low Overhead**: Minimal system resource usage
-- **Different Device Modes**: Profiles for desktops, handhelds, HTPC etc
-
-## Installation
-
-falcond is available on PikaOS via the falcond package or via the Pika Gameutils Metapackage. For other distributions, please check your package manager or build from source.
-
-## Configuration
-
-The configuration file is located at `/etc/falcond/config.conf`. Here's an example configuration, it will be generated automatically on first run:
-
-```
-enable_performance_mode = true
-scx_sched = none
-scx_sched_props = default
-vcache_mode = none
-profile_mode = none
-```
-
-This is global configuration and all options other than profile_mode override individual game profiles.
-
-There is also a list of proton/wine system processes in `/usr/share/falcond/system.conf`. This list can be updated if for example a crash handler is intercepting your profile and needs to be ignored.
-
-### Configuration Options
-
-- `enable_performance_mode`: Enable/disable performance mode (default: true)
-- `scx_sched`: SCX scheduler (options: none, bpfland, lavd, rusty, flash)
-- `scx_sched_props`: SCX scheduler mode (options: default, gaming, power, latency, server)
-- `vcache_mode`: VCache management mode (options: none, cache, freq)
-- `profile_mode`: What type of device is in use, none means desktop (options: none, handheld, htpc)
-
-## Profile Modes
-Falcond now supports different profile modes for different device types:
-- Default (none): Uses profiles from `/usr/share/falcond/profiles`
-- Handheld: Uses profiles from `/usr/share/falcond/profiles/handheld`
-- HTPC: Uses profiles from `/usr/share/falcond/profiles/htpc`
-
-To set a profile mode, add this to your config file:
-```
-profile_mode = "handheld" # or "htpc" or "none"
-```
-
-## Game Profiles
-
-Game profiles are stored in `/usr/share/falcond/profiles/` and define specific optimizations for individual games. You can contribute new profiles via PR at:
-[Falcond Profiles Repository](https://github.com/PikaOS-Linux/falcond-profiles)
-
-Example profile:
-```
-name = "game.exe"
-performance_mode = true
-scx_sched = bpfland
-scx_sched_props = gaming
-vcache_mode = cache
-```
-
-### Available Options
-
-- `name`: The exe name (examples: cs2, PathOfExileSteam.exe)
-- `performance_mode`: Enable/disable performance mode (default: true)
-- `scx_sched`: SCX scheduler (options: none, bpfland, lavd, rusty, flash)
-- `scx_sched_props`: SCX scheduler mode (options: none, gaming, power, latency, server)
-- `vcache_mode`: VCache management mode (options: none, cache, freq)
-
-## Service Management
-
-To restart the daemon:
-```bash
-sudo systemctl restart falcond
-```
-
-To check the status:
-```
-sudo systemctl status falcond
-```
-
-## Source Code
-
-The source code for falcond can be found at:
-[Falcond Source Repository](https://git.pika-os.com/general-packages/falcond)
-
-## Important Notes
-
-⚠️ **Compatibility Warning** ⚠️ falcond should not be used alongside Feral GameMode or Falcon GameMode as they may conflict with each other. falcond provides similar functionality with additional features and optimizations.
-
-## Why falcond?
-
-Traditional gaming on Linux often requires manual optimization for each game - tweaking CPU governors, scheduling priorities, and cache settings. falcond automates this entire process by:
-
-1. Automatically detecting when games are running
-2. Applying optimized settings based on pre-configured profiles
-3. Reverting settings when games are closed
-4. Providing a centralized way to manage gaming performance
-5. Easy switching of options for different device types
-
-This means you can focus on gaming while falcond handles all the technical optimizations in the background!

-## Contributing
-
-Please fork the [PikaOS-Linux/falcond](https://github.com/PikaOS-Linux/falcond) repository and submit a pull request.
-
-## Build Dependencies
-
-zig 0.14.0+
-
-## Building from Source
-
-```
-git clone https://git.pika-os.com/general-packages/falcond.git
-cd falcond
-cd falcond
-zig build -Doptimize=ReleaseFast
-```
-
-## Runtime Dependencies
-
-These should be feature detected by falcond so if not present that specific feature will not be used.
-
-power-profiles-daemon or tuned + tuned-ppd
-scx-sched
-Linux kernel patched with AMD 3D vcache support
-
-## Packaging
-
-falcond should be placed in /usr/bin/falcond and run via a service file. There is an example systemd service file in ./falcond/debian/falcond.service
-
-falcond needs profiles to be useful, these should be placed in /usr/share/falcond/profiles alongside the system.conf in /usr/share/falcond/system.conf. Upto date profiles can be found in the [PikaOS-Linux/falcond-profiles](https://github.com/PikaOS-Linux/falcond-profiles) repository. We currently pull the latest profiles from there on building of this package but you could also package seperately and depend on that package.
-
-There is a config file in /etc/falcond/config.conf which is generated automatically on first run. You could also package that if you need different default settings.
