+It suggests commands as you type, based on command history.

 ## Installation
-```
-    $ git clone git://github.com/tarruda/zsh-autosuggestions ~/.zsh-autosuggestions
-    $ bash ~/.zsh-autosuggestions/install
-```
 
-If you do not have bash, please run it with sh :
+If you already use [zsh-syntax-highlighting](https://github.com/zsh-users/zsh-syntax-highlighting) plugin, then make sure to be loaded **before** zsh-autosuggestions.
 
-`
-sh ~/.zsh-autosuggestions/install
-`
+Note: _.zshrc_ is a file that contains user-specific ZSH configuration.
+ZSH assumes this file in your home directory (i.e. `~/.zshrc`), but the location can be changed using `ZDOTDIR` variable.
 
-Any widget that moves the cursor to the right(forward-word, forward-char...)
-will accept parts of the suggested text. For example, vi-mode users can do

+### Using zgen
+
+[Zgen](https://github.com/tarjoilija/zgen) is a simple and fast plugin manager for ZSH.
+If you don’t use zgen, then use instructions for the manual installation.
+
+1. Load `tarruda/zsh-autosuggestions` and `jimmijj/zsh-syntax-highlighting` using zgen in your .zshrc file, for example:
+
+    ```sh
+    if ! zgen saved; then
+        echo "Creating a zgen save"
+
+        zgen load jimmijj/zsh-syntax-highlighting
+
+        # autosuggestions should be loaded last
+        zgen load tarruda/zsh-autosuggestions
+
+        zgen save
+    fi
+    ```
+
+2. Enable zsh-autosuggestions; copy the following snippet and put it after the zgen config section in your .zshrc file:
+
+    ```sh
+    # Enable autosuggestions automatically.
+    zle-line-init() {
+        zle autosuggest-start
+    }
+    zle -N zle-line-init
+    ```
+
+3. Run `zgen reset` and reopen your terminal.
+
+
+### Manually
+
+1. Clone this repository to `~/.zsh/zsh-autosuggestions` (or anywhere else):
+
+    ```sh
+    git clone git://github.com/tarruda/zsh-autosuggestions ~/.zsh/zsh-autosuggestions
+    ```
+
+2. Clone zsh-syntax-highlighting repository to `~/.zsh/zsh-syntax-highlighting` (or anywhere else):
+
+    ```sh
+    git clone git://github.com/jimmijj/zsh-syntax-highlighting ~/.zsh/zsh-syntax-highlighting
+    ```
+
+3. Load and enable autosuggestions; copy the following snippet and put it to your .zshrc file:
+
+    ```sh
+    # Load zsh-syntax-highlighting.
+    source ~/.zsh/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
+
+    # Load zsh-autosuggestions.
+    source ~/.zsh/zsh-autosuggestions/autosuggestions.zsh
+
+    # Enable autosuggestions automatically.
+    zle-line-init() {
+        zle autosuggest-start
+    }
+    zle -N zle-line-init
+    ```
+
+4. Reopen your terminal.
+
+
+## Uninstallation
+
+Just remove the config lines from .zshrc that you’ve added during “installation.”
+If you don’t use zgen, then also delete `~/.zsh/zsh-autosuggestions` and `~/.zsh/zsh-syntax-highlighting`.
+
+
+## How to use
+
+As you type commands, you will see a completion offered after the cursor, in a muted gray color (which can be changed, see [Configuration](#configuration)).
+To accept the autosuggestion (replacing the command line contents), hit <kbd>End</kbd>, <kbd>Alt+F</kbd>, <kbd>Ctrl+F</kbd>, or any other key that moves the cursor to the right.
+If the autosuggestion is not what you want, just ignore it: it won’t execute unless you accept it.
+
+Any widget that moves the cursor to the right (forward-word, forward-char, end-of-line…) will accept parts of the suggested text.
+For example, vi-mode users can do this:
 
 ```sh
 # Accept suggestions without leaving insert mode
@@ -25,19 +100,37 @@ bindkey '^f' vi-forward-word
 bindkey '^f' vi-forward-blank-word
 ```
 
-Emacs-mode users can simply use alt+f which is bound to forward-word
+You can also use right arrow key to accept the suggested text as in Fish shell; see [Configuration](#configuration) section to enable it.
+
+### Exposed widgets
+
+This plugin defines some ZLE widgets (think about them as functions) which you can bind to some key using [bindkey](http://zshwiki.org/home/zle/bindkeys).
+For example, to toggle autosuggestions using <kbd>Ctrl+T</kbd> add this to your .zshrc:
+
+```sh
+bindkey '^T' autosuggest-toggle
+```
+
+List of widgets:
+
+ - `autosuggest-toggle` – disable/enable autosuggestions.
 
-The [zsh-history-substring-search](https://github.com/zsh-users/zsh-history-substring-search)
-plugin is also recommended.
 
 ## Configuration
 
-You may override default global config variables after plugin load.
