 ```bash
-# build app in arceos directory
-make A=path/to/app ARCH=<arch> LOG=<log>
+# cd arceos directory
+cd arceos
+# build&run app  in arceos directory
+# clean everything
+make clean
+# Example Pattern: make ARCH=<arch>  LOG=<log> A=path/to/app FEATURES=...  run
+# riscv64 example
+make ARCH=riscv64 LOG=debug A=examples/helloworld run
+# x86_64 example
+make clean
+make ARCH=x86_64 LOG=debug A=examples/helloworld run
+# aarch64 example
+make clean
+make ARCH=aarch64 LOG=debug A=examples/helloworld run
+# loongarch64 example
+make clean
+make ARCH=loongarch64 LOG=debug A=examples/helloworld run
 ```
 
 Where `path/to/app` is the relative path to the application. Examples applications can be found in the [examples](examples/) directory or the [arceos-apps](https://github.com/arceos-org/arceos-apps) repository.
