+# Installation
+
+> [!CAUTION]
+> Wild Kernels is not responsible for bricked devices or damage. By flashing, you assume all risk. Back up your data and understand the risks before flashing.
+
+## Choose your method
+
+| Method | When to use | Requires root | Guide |
+|--------|-------------|---------------|-------|
+| **Custom Recovery** | Flash AnyKernel3 ZIP for your model/OneUI branch | No (unlocked bootloader) | See below |
+| **Kernel Flasher** | Upgrading with root already available, no PC needed | Yes | [Kernel Flasher](https://github.com/fatalcoder524/KernelFlasher) |
+
+## Prerequisites
+
+- [ ] Samsung device with an unlocked bootloader
+- [ ] Full backup (at minimum the `boot` partition or have a stock unmodified `boot.img`/`AP` tar)
+- [ ] Correct AnyKernel3 ZIP for your model/OneUI branch from [Releases](https://github.com/WildKernels/Samsung_KernelSU_SUSFS/releases)
+
+### Supported branches
+
+Samsung branches are per model + OneUI version (e.g. `SM-S938B-Oneui8.5`, `SM-S928B-Oneui7`, `SM-A546B-Oneui7`). See the matrix in [`.github/workflows/kernel-samsung.yml`](../.github/workflows/kernel-samsung.yml) for the full list. Match exactly to your device/OneUI version.
+
+## Flashing via recovery
+
+1. Download the AnyKernel3 ZIP matching your `BRANCH` (model + OneUI) and desired variant (KSUN/KSU/RESUKISU + features).
+2. Boot to custom recovery (TWRP/OrangeFox).
+3. Flash the ZIP — AnyKernel3 will patch the boot image in place.
+4. Reboot to system.
+
+For GKI generic instructions and manager setup, see also [GKI Installation Guide](https://github.com/WildKernels/GKI_KernelSU_SUSFS/blob/dev/docs/installation.md).
+
+## After flashing
+
+- Install your root manager (KernelSU-Next / KernelSU / ReSukiSU manager matching the flavor you flashed).
+- If you flashed with SUSFS, install the SUSFS module: [sidex15/susfs4ksu-module](https://github.com/sidex15/susfs4ksu-module) and verify hiding.
+- Check KernelSU app shows working, and test root with a root checker.
