+The default option is setting the configuration in `typos.toml`, `_typos.toml` or `.typos.toml`.

+In addition, you can set the same configuration with standard python's config file `pyproject.toml` by adding `[tool.typos.xyz]` where the `xyz` is the same as in default `_typos.toml` so the sample configuration above will be:
+```toml
+[tool.typos.default]
+extend-ignore-identifiers-re = ["AttributeID.*Supress.*"]
+
+[tool.typos.default.extend-identifiers]
+AttributeIDSupressMenu = "AttributeIDSupressMenu"
+
+[tool.typos.default.extend-words]
+teh = "teh"
