+
+## Requirements
+
+These targets can be cross-compiled with a target vsb. Std is partially supported.
+
+## Building the target
+
+You can build Rust with support for the targets by adding it to the `target` list in `config.toml`. In addition the workbench and wr-cc have to configured and activated.
+
+```toml
+[build]
+build-stage = 1
+target = [
+    "<HOST_TARGET>",
+    "x86_64-wrs-vxworks",
+    "aarch64-wrs-vxworks",
+    "i686-wrs-vxworks",
+    "armv7-wrs-vxworks-eabihf",
+    "powerpc-wrs-vxworks",
+    "powerpc-wrs-vxworks-spe",
+]
+```
+
+## Building Rust programs
+
+Rust does not yet ship pre-compiled artifacts for VxWorks.
+
+The easiest way to build and test programs for VxWorks is to use the shipped pre compiled rustc and cargo in VxWorks workbench, following the official windriver guidelines on this.
+
+## Cross-compilation toolchains and C code
+
+The target supports C code. Pre-compiled C toolchains can be found in provided VxWorks workbench.
