+# Documentation Writing Guidelines
+
+## Best Practices
+
++ Check the spelling and grammar, even if you have to copy and paste from an external source.
++ Use simple sentences. Easy-to-read sentences mean the reader can quickly use the guidance you share.
++ Try to express your thoughts in a concise and clean way.
++ Don't abuse `code` format when writing in plain English.
++ Follow Google developer documentation [style guide](https://developers.google.com/style).
++ Check the meaning of words in Microsoft's [A-Z word list and term collections](https://docs.microsoft.com/en-us/style-guide/a-z-word-list-term-collections/term-collections/accessibility-terms) (use the search input!).
