+## Cross-compiling
+A cross compilation environment is provided as a docker image.
+Build the image from the root of the project with the following command :
+
+```
+$ docker build -t librespot-cross -f contrib/Dockerfile .
+```
+
+The resulting image can be used to build librespot for linux x86_64, armhf and armel.
+The compiled binaries will be located in /tmp/librespot-build
+
+```
+docker run -v /tmp/librespot-build:/build librespot-cross
+```
+
+If only one architecture is desired, cargo can be invoked directly with the appropriate options :
+```shell
+docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --no-default-features --features "with-syntex alsa-backend"

 ## Development
 When developing *librespot*, it is preferable to use Rust nightly, and build it using the following :
