+# Specify The Language For A File With Bat
+
+The `bat` utility is able to correctly infer the language of most files it
+prints based on the file extension. In some cases, you may want to specify a
+language other than the one it guesses.
+
+For instance, here is a React file printed with `bat`:
+
+![bat with no CLI args](https://i.imgur.com/Jk0L6tB.png)
+
+The `jsx` syntax doesn't look great because of the inferred language
+highlighting doesn't account for it. We can get better results by telling
+`bat` that the file should be parsed as `JavaScript (Babel)`.

+
+By including `--language=jsx` as a flag, `bat` uses a different language
+parser and the output is now what I'm looking for.
