+# TOML Validator
+
+If Go is installed, it's simple to try it out:
+
+```bash
+go get github.com/BurntSushi/toml/cmd/tomlv
+tomlv some-toml-file.toml
+```
+
+You can see the types of every key in a TOML file with:
+
+```bash
+tomlv -types some-toml-file.toml
+```
+
+At the moment, only one error message is reported at a time. Error messages
+include line numbers. No output means that the files given are valid TOML, or 
+there is a bug in `tomlv`.
+
+Compatible with TOML version
+[v0.1.0](https://github.com/mojombo/toml/blob/master/versions/toml-v0.1.0.md)
