+* [musl-based GCC toolchains](https://musl.cc/) (only for building [user programs](https://github.com/rcore-os/rcore-user))
 
-See [Travis script](./.travis.yml) for details.
+Setup on Linux or macOS:
+
+```bash
+$ rustup component add rust-src llvm-tools-preview
+$ cargo install cargo-binutils cargo-xbuild
+```
+
+Or use Docker container:
+
+```bash
+$ docker run -it -v $PWD:$PWD -w $PWD wangrunji0408/rcore
+```
 
 ### How to run
 
-```bash
-$ rustup component add rust-src llvm-tools-preview
-$ cargo install cargo-binutils
-$ cargo install cargo-xbuild
-```
-
 ```bash
 $ git clone https://github.com/rcore-os/rCore.git --recursive
 $ cd rCore/user
-$ make sfsimg arch={riscv32,riscv64,x86_64,aarch64,mipsel} # requires $(arch)-linux-musl-gcc
