+# `i686-unknown-hurd-gnu`
+
+**Tier: 3**
+
+[GNU/Hurd] is the GNU Hurd is the GNU project's replacement for the Unix kernel.
+
+## Target maintainers
+
+- Samuel Thibault, `samuel.thibault@ens-lyon.org`, https://github.com/sthibaul/
+
+## Requirements
+
+The target supports host tools.
+
+The GNU/Hurd target supports `std` and uses the standard ELF file format.
+
+## Building the target
+
+This target can be built by adding `i686-unknown-hurd-gnu` as target in the rustc list.
+
+## Building Rust programs
+
+Rust does not yet ship pre-compiled artifacts for this target. To compile for
+this target, you will either need to build Rust with the target enabled (see
+"Building the target" above), or build your own copy of `core` by using
+`build-std` or similar.
+
+## Testing
+
+Tests can be run in the same way as a regular binary.
+
+## Cross-compilation toolchains and C code
+
+The target supports C code, the GNU toolchain calls the target
+`i686-unknown-gnu`.
