 ### Step 2: Adding `zoxide` to your shell
 
-By default, `zoxide` defines the `z`, `zi`, `za`, `zq`, and `zr` aliases. If you'd like to go with just the barebones `z`, pass the `--no-define-aliases` flag to `zoxide init`.
+If you currently use `z`, `z.lua`, or `zsh-z`, you may want to first migrate your existing database to `zoxide`:

 ## Configuration
 
+### `init` flags
+
+- `--no-define-aliases`: don't define extra aliases like `zi`, `zq`, `za`, and `zr`
+- `--hook <HOOK>`: change the event that adds a new entry to the database (default: `prompt`)
+  - `none`: never add entries - this will make `zoxide` useless unless you manually configure a hook
+  - `prompt`: add an entry at every prompt
+  - `pwd`: add an entry whenever you change directories
+
 ### Environment variables
 
+- `$_ZO_ECHO`: `z` will print the matched directory before navigating to it
 - `$_ZO_DATA`: sets the location of the database (default: `~/.zo`)
 - `$_ZO_MAXAGE`: sets the maximum total rank after which entries start getting deleted
