+# Configure cd To Behave Like pushd In Zsh
+
+The Zsh environment has a setting that allows you to make the `cd` command
+behave like the `pushd` command. Normally when you use `cd` the [remembered
+directory stack](list-the-stack-of-remembered-directories.md) is not
+effected. However, if you add the following setting to your `~/.zshrc` file:
+
+```bash
+setopt auto_pushd
+```
+
+then using `cd` to navigate directories will cause those directories to be
+added to the `dirs` stack.
+
+This is the default in the [oh-my-zsh configuration of
+zsh](https://github.com/robbyrussell/oh-my-zsh/blob/master/lib/directories.zsh#L2).
