+# `mipsel-unknown-linux-gnu`
+
+**Tier: 3**
+
+Little-endian 32 bit MIPS for Linux with `glibc.
+
+## Target maintainers
+
+- [@LukasWoodtli](https://github.com/LukasWoodtli)
+
+## Requirements
+
+The target supports std on Linux. Host tools are supported but not tested.
+
+
+## Building the target
+
+For cross compilation the GNU C compiler for the mipsel architecture needs to
+be installed. On Ubuntu install the packets: `gcc-mipsel-linux-gnu` and
+`g++-mipsel-linux-gnu`.
+
+Add `mipsel-unknown-linux-gnu` as `target` list in `config.toml`.
+
+## Building Rust programs
+
+Rust does not ship pre-compiled artifacts for this target. To compile for
+this target, you will need to build Rust with the target enabled (see
+"Building the target" above).
