-Documentation can be generated with `make docs` and cleaned up with `make clean-docs`. The resulting files are located in `doc/doxygen/html`; open `index.html` to view the homepage.
+Recommendations:
-Before running `make docs`, you will need to install dependencies `doxygen` and `dot`. For example, on macOS via Homebrew:
-```
-brew install graphviz doxygen
-```
+- Avoiding duplicating type and input/output information in function
+ descriptions.
+
+- Use backticks (&#96;&#96;) to refer to `argument` names in function and
+ parameter descriptions.
+
+- Backticks aren't required when referring to functions Doxygen already knows
+ about; it will build hyperlinks for these automatically. See
+ http://www.doxygen.nl/manual/autolink.html for complete info.
+
+- Avoid linking to external documentation; links can break.
+
+- Javadoc and all valid Doxygen comments are stripped from Doxygen source code
+ previews (`STRIP_CODE_COMMENTS = YES` in [Doxyfile.in](doc/Doxyfile.in)). If
+ you want a comment to be preserved, it must instead use `//` or `/* */`.
+
+### Generating Documentation
+
+The documentation can be generated with `make docs` and cleaned up with `make
+clean-docs`. The resulting files are located in `doc/doxygen/html`; open
+`index.html` in that directory to view the homepage.
+
+Before running `make docs`, you'll need to install these dependencies:
+
+Linux: `sudo apt install doxygen graphviz`
+
+MacOS: `brew install doxygen graphviz`
