+### Shared Directories
+
+- **`binaries/`** - Compiled binaries sorted by architecture
+- **`packages/`** - OpenWrt `.ipk` packages
+- **`src/`** - Original source code (shared reference)
+- **`opkg-repo/`** - Package repository for deployment
+- **`agent-notes/`** - Research, build results, SDK documentation
+
+## Architecture Overview
+
+| Router | Model | SoC | Architecture | Bits | OpenWrt Target |
+|--------|-------|-----|--------------|------|----------------|
+| **Flint1** | GL-AX1800 | Qualcomm IPQ6000 | ARMv7 rev 4 | 32-bit | ipq40xx |
+| **Flint2** | GL-MT6000 | MediaTek MT7986A | ARMv8 rev 4 (aarch64) | 64-bit | mediatek-filogic |
+
+**Note:** Different architectures require **separate binaries**.
+
+## Quick Start
+
+### Flint1 (ARMv7)
+
+```bash
+cd flint1-armv7/build
+./download-armv7-toolchain.sh  # First time only
+./build-btop-armv7.sh
+```
+
+### Flint2 (aarch64)
+
+Binaries already built and available in `binaries/flint2/`.
+
+To rebuild:
+```bash
+cd flint2-aarch64/sdk/openwrt-sdk-mediatek-filogic_gcc-14.3.0_musl.Linux-x86_64/
+./scripts/feeds update -a
+make package/<name>/compile
+```
+
+## Documentation
+
+- **Flint1 SDK Research:** `agent-notes/flint1-sdk-research.md`
+- **Flint1 Build Results:** `agent-notes/glax1800-build-results.md`
+- **Implementation Plan:** `.gemini/antigravity/brain/.../implementation_plan.md`
+
+## Build Scripts
+
+- `build-ipk.sh` - Create .ipk packages
+- `build-verified-ipk.sh` - Build with verification
+- `generate-index.sh` - Generate opkg repository index
+- `upload-repo.sh` - Upload to repository server
+
+## Active Toolchains
+
+**Flint1:** musl.cc armv7l-linux-musleabihf (GCC 11.2.1)  
+**Flint2:** OpenWrt mediatek-filogic SDK (GCC 14.3.0)
