+# TOML Validator
+
+If Go is installed, it's simple to try it out:
+
+    $ go install github.com/BurntSushi/toml/cmd/tomlv@master
+    $ tomlv some-toml-file.toml
+
+You can see the types of every key in a TOML file with:
+
+    $ 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`.
