+# 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!

+
+## 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.
