fix update zsh issue

@@ -39,10 +39,38 @@ If the variable isn't set, the plugin will default to use `.env`.
 For example, this will make the plugin look for files named `.dotenv` and load them:
 
 ```
+
+### ZSH_DOTENV_PROMPT
+
+Set `ZSH_DOTENV_PROMPT=false` in your zshrc file if you don't want the confirmation message.
+You can also choose the `Always` option when prompted to always allow sourcing the .env file
+in that directory. See the next section for more details.
+
+### ZSH_DOTENV_ALLOWED_LIST, ZSH_DOTENV_DISALLOWED_LIST
+
+The default behavior of the plugin is to always ask whether to source a dotenv file. There's
+a **Y**es, **N**o, **A**lways and N**e**ver option. If you choose Always, the directory of the .env file
+will be added to an allowed list; if you choose Never, it will be added to a disallowed list.
+If a directory is found in either of those lists, the plugin won't ask for confirmation and will
+instead either source the .env file or proceed without action respectively.
+
+The allowed and disallowed lists are saved by default in `$ZSH_CACHE_DIR/dotenv-allowed.list` and
+`$ZSH_CACHE_DIR/dotenv-disallowed.list` respectively. If you want to change that location,
+change the `$ZSH_DOTENV_ALLOWED_LIST` and `$ZSH_DOTENV_DISALLOWED_LIST` variables, like so:
+
+```zsh
 # in ~/.zshrc, before Oh My Zsh is sourced:
-ZSH_DOTENV_FILE=.dotenv
+ZSH_DOTENV_ALLOWED_LIST=/path/to/dotenv/allowed/list
+ZSH_DOTENV_DISALLOWED_LIST=/path/to/dotenv/disallowed/list
 ```
 
+The file is just a list of directories, separated by a newline character. If you want
+to change your decision, just edit the file and remove the line for the directory you want to
+change.
+
+NOTE: if a directory is found in both the allowed and disallowed lists, the disallowed list
+takes preference, _i.e._ the .env file will never be sourced.
+
 ## Version Control
 
 **It's strongly recommended to add `.env` file to `.gitignore`**, because usually it contains sensitive information such as your credentials, secret keys, passwords etc. You don't want to commit this file, it's supposed to be local only.
