+# A Better Way To Reload ZSH Configuration
+
+I have an alias in my `~/.zshrc` that I set up to make it easy to "reload" my
+ZSH configuration. This is handy if I'm iterating on some changes to my
+`~/.zshrc` file and need verify them as I go.
+
+```bash
+alias reload='source ~/.zshrc'
+```
+
+With this alias, I can call `reload` from the terminal and the latest version
+of my configuration (according to the `~/.zshrc` file) will be loaded for that
+shell instance.
+
+This has some downsides. It doesn't account for the other kinds of files that
+contribute to your shell configuration (e.g. `~/.zprofile`) and it can lead to
+duplicate values in your `PATH` and init scripts being run an additional time.
+
+A better way is to use:
+
+```bash
+$ omz reload
+```
+
+This is [a wrapper call around `exec
+zsh`](https://github.com/ohmyzsh/ohmyzsh/blob/master/lib/cli.zsh#L669-L677),
+which restarts the `zsh` process. It also clears the completion cache.
+
+I've since updated my `~/.zshrc` alias for `reload`:
+
+```bash
+alias reload='omz reload'
+```
