+## Changing where functions are configured
+
+By default, the functions are defined in `/etc/bash.bashrc` and `/etc/zsh/zshrc` if the container user is `root`, otherwise `~/.bashrc` and `~/.zshrc`.
+This default configuration ensures that the functions are always available for any interactive shells.
+
+In some cases it can be useful to have the functions written to a non-default location. For example:
+- the configuration file of a shell other than `bash` and `zsh`
+- a custom file which is not a shell configuration script (so that it can be `source`d in non-interactive shells and scripts)
+
+To do this, set the `targetFiles` option to the path script path where the functions should be written. Note that the default paths WILL NOT be used
+if the `targetFiles` option is provided, so you may want to include them in the overridden value, or add `source` the custom script in those configurations:
+
+```bash
+# .devcontainer/devcontainer.json
+{
+    // ...
+    "targetFiles": "/custom/path/to/auth-helper.sh"
+}
+
+# ~/.bashrc
+
+source /custom/path/to/auth-helper.sh
+```
