### Check the README Syntax
GitHub is a bit forgiving when it comes to the RST syntax in the README but PyPI is not.
-So slightly broken RST can cause the PyPI page to not render the correct content. Check
-using the `rst2html.py` script that comes with docutils:
-
-```
-rst2html.py --no-raw README.rst > index.html
-```
-
-Open `index.html` and check for any flaws or error messages.
+To check the README syntax, visit the
+[PyGMT TestPyPI release history](https://test.pypi.org/project/pygmt/#history), select
+the latest commit, and review the left sidebar and project description for any errors.
