-  0. Add your grammar to [`grammars.yml`][grammars] by running `script/convert-grammars --add vendor/grammars/MyGrammar`.
-  0. Download the license for the grammar: `script/licensed`. Be careful to only commit the file for the new grammar, as this script may update licenses for other grammars as well.

+### There's a problem with the syntax highlighting of a file
+
+Linguist detects the language of a file but the actual syntax-highlighting is powered by a set of language grammars which are included in this project as a set of submodules [and may be found here](https://github.com/github/linguist/blob/master/vendor/README.md).
+
+If you experience an issue with the syntax-highlighting on GitHub, **please report the issue to the upstream grammar repository, not here.** Grammars are updated every time we build the Linguist gem and so upstream bug fixes are automatically incorporated as they are fixed.

 ## Overrides
 
 Linguist supports a number of different custom overrides strategies for language definitions and vendored paths.

+#
+#  - libs_section_prefix
+#  - libs_section_postfix
+#      The contents of these strings, if specified, will be placed around

+#      the post_link parameter.
+#  - post_link
+#      The content of this string, if specified, will be run as a separate
+#      command following the the link command.
+#  - deps
+#      Just forwarded to the toolchain definition.
+#  - executable_extension
+#      If this string is specified it will be used for the file extension

+#      The contents of this string, if specified, will be passed as a #define
+#      to the toolchain. It can be used to force recompiles whenever a
+#      toolchain is updated.
