+# Android / Termux
+
+Flow's Android VM path boots the same pinned Tiny Core CorePure64 guest used by normal `flow-kernel` QEMU runs. Android is only the QEMU host; there is no bootloader replacement, Android kernel modification, root requirement, or separate Flow kernel architecture.
+
+This path requires a 64-bit Termux installation. The current canonical guest is x86_64 CorePure64 and therefore runs through QEMU TCG on ARM64 Android. A native ARM64 guest should only be added when the canonical Tiny Core substrate and Flow target support it rather than creating a phone-only fork.
+
+From the repository root in Termux:
+
+```sh
+bash android/setup-termux.sh
+bash android/run.sh
+```
+
+`android/setup-termux.sh` enables the Termux X11 repository and installs the maintained `qemu-system-x86-64` package plus the tools used by `tinycore/fetch.sh`. `android/run.sh` then delegates directly to `tinycore/run.sh`, so image pinning, checksum verification, serial console behaviour, RAM configuration, and kernel command-line overrides stay identical to the normal Flow kernel path.
+
+The Tiny Core artifacts are cached under `build/tinycore` by default. Pass another build directory as the first argument to `android/run.sh` if needed.
+
+Useful overrides are the same as the canonical runner:
+
+```sh
+FLOW_KERNEL_RAM=512M bash android/run.sh
+FLOW_KERNEL_CMDLINE="debug" bash android/run.sh
+```
