 1. Get a bot token ( [BotFather](https://telegram.me/botfather) )
 2. `$ npm install -g node-telme`
 3. `$ telme --init`
-4. Do something :)
+4. Need help? `$ telme --help`

 ## How do i get a bot token?
 - Get a telegram bot token from the botFather

 ## Configure `telme`

-Simply run `$ telme --init` and follow the easy steps. You will need the bot token at this stage.
+Simply run `$ telme --init` and follow 2 easy steps. You will need the bot token at this stage.
 This will help you generate a `.telmeconfig` file in your home directory. You can always run `--init` again to override values or just edit the file yourself.

+## Profiles
+
+You can set multiple profiles, that will target different bots and/or different chats.
+> You can use the same bot in all profiles if you like, But the target chat can be different
+
+To initialize a new profile:
+```shell
+$ telme --init --profile <profile_name>
+```
+
 ## Examples:
 ###### Simple message
-```
+```shell
 $ telme --m "Message to send"
 ```
+
+In the next example a message will be sent every time the user `user` logs in to a tty.
+> Added the next lines at the bottom of `~/.profile` file
+```shell
+# Telme on login
+telme --m "A new Login:\n\`\`\` user: $(whoami) | hostname: $(hostname) | remote ip $(who | cut -d'(' -f2 | cut -d')' -f1)\`\`\` Hope this is you!"
+```
+
 ###### Task message
 Task messages are a simple way to receive a message from your bot once a command has been finished. It will also let you know if you had any errors.
-```
+```shell
 $ telme docker build . -t my-image/build/that/takes/for/ever
 ```
 In this example, once the docker build has finished you will receive a message.

-```
-$ telme npm run test
-```
+As mentioned before - you can also specify a profile.

+```shell
+$ telme -p movie-club curl https://example.com/large/file/download.mp4
 ```
-$ telme do-a-long-task
-```
+this will send the message to the `movie-club` profile chat. (By the `movie-club` bot)
