+# fyne-xgo-docker
+
+This project contains files for building a docker container based on [xgo](https://github.com/techknowlogick/xgo) that contains all of Fyne's dependencies for various architectures.
+
+This allows for building Fyne programs for multiple architectures easily. Currently, the following platforms are supported:
+
+- `linux/amd64`
+- `linux/386`
+- `linux/arm64`
+- `linux/arm` (`GOARM=7`)
+
+The `xgo` build script has been modified so that the `SOURCE_DIR` and `BUILD_DIR` environment variables correspond to where `xgo` look for sources and where it puts its output binaries. This allows for easy use within Continuous Integration engines.
+
+The entrypoint has also been removed to allow running other commands, so run `/build.sh` if you want to start the build.
