+## One-click x86/64 APK build
+
+On a Debian or Ubuntu x86_64 host, run the script as an unprivileged user:
+
+```sh
+bash build.sh
+```
+
+The script installs the required APT packages with `sudo`, clones ImmortalWrt
+`v25.12.1` into `.build/immortalwrt`, configures the generic x86/64 target, and
+builds only mihomo. Generated APK files are copied to `./dist/`.
+
+To skip APT installation on later runs:
+
+```sh
+SKIP_DEPS=1 bash build.sh
+```
+
+The build directory, job count, and source version can be overridden:
+
+```sh
+WORK_DIR=/path/to/build JOBS=8 IMMORTALWRT_VERSION=v25.12.1 bash build.sh
+```
+
+The repository and build paths must be on a case-sensitive filesystem and must
+not contain spaces or non-ASCII characters.
