 ### Suggestion Highlight Style

+Set `ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE` to configure the style that the suggestion is shown with. The default is `fg=8`, which will set the foreground color to color 8 from the [256-color palette](https://upload.wikimedia.org/wikipedia/commons/1/15/Xterm_256color_chart.svg). If your terminal only supports 8 colors, you will need to use a number between 0 and 7.
+
+Background color can also be set, and the suggestion can be styled bold, underlined, or standout. For example, this would show suggestions with bold, underlined, pink text on a cyan background:
+
+```sh
+ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE="fg=#ff00ff,bg=cyan,bold,underline"
+```
+
+For more info, read the Character Highlighting section of the zsh manual: `man zshzle` or [online](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting).
+
+**Note:** Some iTerm2 users have reported [not being able to see the suggestions](https://github.com/zsh-users/zsh-autosuggestions/issues/416#issuecomment-486516333). If this affects you, the problem is likely caused by incorrect color settings. In order to correct this, go into iTerm2's setting, navigate to profile > colors and make sure that the colors for Basic Colors > Background and ANSI Colors > Bright Black are **different**.


 ### Suggestion Strategy

+`ZSH_AUTOSUGGEST_STRATEGY` is an array that specifies how suggestions should be generated. The strategies in the array are tried successively until a suggestion is found. There are currently three built-in strategies to choose from:

 - `history`: Chooses the most recent match from history.
+- `completion`: Chooses a suggestion based on what tab-completion would suggest. (requires `zpty` module, which is included with zsh since 4.0.1)
 - `match_prev_cmd`: Like `history`, but chooses the most recent match whose preceding history item matches the most recently executed command ([more info](src/strategies/match_prev_cmd.zsh)). Note that this strategy won't work as expected with ZSH options that don't preserve the history order such as `HIST_IGNORE_ALL_DUPS` or `HIST_EXPIRE_DUPS_FIRST`.

+For example, setting `ZSH_AUTOSUGGEST_STRATEGY=(history completion)` will first try to find a suggestion from your history, but, if it can't find a match, will find a suggestion from the completion engine.

 ### Disabling suggestion for large buffers

 Set `ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE` to an integer value to disable autosuggestion for large buffers. The default is unset, which means that autosuggestion will be tried for any buffer size. Recommended value is 20.
-This can be useful when pasting large amount of text in the terminal, to avoid triggering autosuggestion for too long strings.
+This can be useful when pasting large amount of text in the terminal, to avoid triggering autosuggestion for strings that are too long.

-### Enable Asynchronous Mode
+### Asynchronous Mode

-As of `v0.4.0`, suggestions can be fetched asynchronously using the `zsh/zpty` module. To enable this behavior, set the `ZSH_AUTOSUGGEST_USE_ASYNC` variable (it can be set to anything).
+Suggestions are fetched asynchronously by default in zsh versions 5.0.8 and greater. To disable asynchronous suggestions and fetch them synchronously instead, `unset ZSH_AUTOSUGGEST_USE_ASYNC` after sourcing the plugin.
+
+Alternatively, if you are using a version of zsh older than 5.0.8 and want to enable asynchronous mode, set the `ZSH_AUTOSUGGEST_USE_ASYNC` variable after sourcing the plugin (it can be set to anything). Note that there is [a bug](https://github.com/zsh-users/zsh-autosuggestions/issues/364#issuecomment-481423232) in versions of zsh older than 5.0.8 where <kbd>ctrl</kbd> + <kbd>c</kbd> will fail to reset the prompt immediately after fetching a suggestion asynchronously.
+
+### Disabling automatic widget re-binding
+
+Set `ZSH_AUTOSUGGEST_MANUAL_REBIND` (it can be set to anything) to disable automatic widget re-binding on each precmd. This can be a big boost to performance, but you'll need to handle re-binding yourself if any of the widget lists change or if you or another plugin wrap any of the autosuggest widgets. To re-bind widgets, run `_zsh_autosuggest_bind_widgets`.
+
+### Ignoring history suggestions that match a pattern
+
+Set `ZSH_AUTOSUGGEST_HISTORY_IGNORE` to a [glob pattern](http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Operators) to prevent offering suggestions for history entries that match the pattern. For example, set it to `"cd *"` to never suggest any `cd` commands from history. Or set to `"?(#c50,)"` to never suggest anything 50 characters or longer.
+
+**Note:** This only affects the `history` and `match_prev_cmd` suggestion strategies.
+
+### Skipping completion suggestions for certain cases
+
+Set `ZSH_AUTOSUGGEST_COMPLETION_IGNORE` to a [glob pattern](http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Operators) to prevent offering completion suggestions when the buffer matches that pattern. For example, set it to `"git *"` to disable completion suggestions for git subcommands.
+
+**Note:** This only affects the `completion` suggestion strategy.
