 You can create groups per chat to mention every user that joined the group by calling one command instead of mentioning them one by one.
 
+## Usage
+First, users need to join the group to let mentioning them, to do that, they simply need to join specific group.
+It can be done in 2 ways:
+- Command [`/join`](#join)
+- [Inline Mode](#inline-mode-usage)
+
+Users that have joined the group can be mentioned in 3 ways:
+- [Dynaminc Mentioning](#dynamic-mentioning) by `@`, for example `@everyone`
+- Command [`/everyone`](#everyone)
+- [Inline Mode](#inline-mode-usage)
+
+To leave the group use one of the two ways:
+- Command [`/leave`](#leave)
+- [Inline Mode](#inline-mode-usage)
+
+To display available groups:
+- Command [`/groups`](#groups)
+
+## Dynamic mentioning
+You can use `@` character (as you would mention a user) to mention specific group.
+
+All the below will mention users from `default` group.
+
+`@all`, `@channel`, `@chat`, `@everyone`, `@group`, `@here`.
+
+If you did create a group named `gaming`, you can simply use `@gaming` in your text to mention them all.
 ## Commands
 *Important*: `{group-name}` is not required, if not given, it will be set to `default`.

-## Inline Mode
-Using Inline Mode is recommended because policy of bots with privacy mode enabled (https://core.telegram.org/bots/faq#what-messages-will-my-bot-get) says that command trigger is sent (without mentioning the bot) only to the last mentioned bot. So if you do have multiple bots in current chat, I might not receive your command!
-
-### Usage
+### Inline Mode Usage
 To use inline mode, type `@everyone_mention_bot` in telegram message input or click on the `Inline Mode` button from `/start` command.
