-Set the `postcss-oldest-supported` depending on community needs. This can be the same as the `postcss` version.

+## updating
+
+- only update `postcss-tape`
+- run `npm run lint` from the root
+
+This will update the peer dependency version for PostCSS in all packages and plugins.
+
+## most recent version
+
+- kept up to date
+- only used in CI to catch regressions
+
+## oldest supported
+
+- used as the peer dependency version in all plugins and packages
+- updated based on community needs
+- can be the same as the **most recent version** version
+
+## semver flags
 
 - Plugins use `^MAJOR.MINOR`.
 - PostCSS Tape uses `~MAJOR.MINOR`.
 
+## notes
+
 Avoid increasing these versions when possible.
 
 Major version updates are also always a breaking change.
