+# Quick start
+
+## Requirements
 
 Only thing that you must have - installed docker. Please follow the original
-instruction [how to install docker](https://docs.docker.com/get-docker/)
+instruction <a href="https://docs.docker.com/get-docker/" target="_blank" rel="noopener">how to install docker -></a>.
+
+When you are ready - come back and follows the below steps to send the first text message to WhatsApp via HTTP API!
+
+{{< details "Why Docker?" >}}
+Docker makes it easy to ship all-in-one solution with the runtime and dependencies. You don't have to worry about
+language-specific libraries or chrome installation.
+
+Also Docker makes installation and update processes so simple, just one command!
+{{< /details >}}
+
+## Send your first message
+
+Let's go over steps that allow you to send your first text message via WhatsApp HTTP API!
+
+### 1. Download image
+
+Assuming you have installed [Docker](https://docs.docker.com/get-docker/), let's download the image.
+
 
 ```bash
-docker pull allburov/whatsapp-http-api
+docker pull devlikeapro/waha
 ```
 
-# First Steps
 
-We're going to go through basic steps and send a text message at the end!
+```bash
+docker login -u devlikeapro -p {KEY}
+docker pull devlikeapro/waha-plus
+docker logout
+```
 
-## Run WhatsAPP HTTP API
+Read more about how to get `PASSWORD` for [Plus Version →]({{< relref "plus-version" >}})
+
+### 2. Run WhatsApp HTTP API
 
 Run WhatsApp HTTP API:
 
 ```bash
-docker run -it --rm -v `pwd`/tokens:/app/tokens -p 127.0.0.1:3000:3000/tcp --name whatsapp-http-api allburov/whatsapp-http-api
+docker run -it --rm -p 3000:3000/tcp --name waha devlikeapro/waha
 
-# It prints logs and the last line must be 
+# It prints logs and the last line must be
 # WhatsApp HTTP API is running on: http://[::1]:3000
 ```
 
-Open the link in your browser: http://localhost:3000/
+Open the link in your browser [http://localhost:3000/](http://localhost:3000/) and you'll see API documentation
+(Swagger).
 
-Note: We don't recommend expose the API outside the world because it does not
-support ([yet](https://github.com/allburov/whatsapp-http-api/issues/4)) authorization!
 
-## Create a new session and login
+### 3. Start a new session
 
-1. To start a new session you should have your mobile phone with installed WhatsApp application close to you. Please go
-   and read how what we'll need to a bit
-   later: [How to log in - the instruction on WhatsApp site](https://faq.whatsapp.com/381777293328336/?helpref=hc_fnav)
-1. Open API documentation at http://localhost:3000/
-1. **Start a new session with a name** (you can use `default` for the start)  - find `POST /api/session/start`, click
-   on **Try it out**, then **Execute** a bit below.
-   ![](./docs/images/session-start.png)
-1. **Scan QR Code** - find `GET /api/screenshot` and execute it, it'll show you QR code that you must scan with your
-   device.
-   ![](./docs/images/qr.png)
-1. **Get a screenshot again** - it'll show you the screenshot of you Whatsapp instance. If you can get the actual
-   screenshot - then you're ready to start sending messages!
-   ![](./docs/images/screenshot.png)
+To start a new session you should have your mobile phone with installed WhatsApp application close to you.
 
-## Send a text message
+Please go and read how what we'll need to a bit
+later:
+<a href="https://faq.whatsapp.com/381777293328336/?helpref=hc_fnav" target="_blank">
+How to log in - the instruction on WhatsApp site
+</a>
 
-Let's try to send a message - you can either find `POST /api/sendText`  in swagger (http://localhost:3000/) or
-use `curl` or just open a link in a browser (change the phone
-before!) http://localhost:3000/api/sendText?phone=79776772457&text=Hello+from+WhatsApp+HTTP+API+Free!
+When your ready - find `POST /api/session/start`, click on **Try it out**, then **Execute** a bit below.
+
+
+The example payload:
+```json
+{
+  "name": "default"
+}
+```
+
+
+By using the request with `name` values you can start multiple session (WhatsApp accounts) inside the single docker container in Plus
+
+
+### 4. Get and scan QR
+
+Find `GET /api/screenshot` and execute it, it shows you QR code.
+
+
+**Scan the QR with your cell phone's WhatsApp app.**
+
+
+### 5. Get the screenshot
+
+Execute `GET /api/screenshot` after a few seconds after scanning the QR - it'll show you the screenshot of you Whatsapp
+instance. If you can get the actual screenshot - then you're ready to start sending messages!
+
+
+### 6. Send a text message
+
+Let's send a text message - find `POST /api/sendText`  in [swagger](http://localhost:3000/) and change `chatId` this
+way: use a phone international phone number without `+` symbol and add `@c.us` at the end.
+
+For phone number `12132132131` the `chatId` is  `12132132131@c.us`.
+
+The example payload:
+```json
+{
+  "chatId": "12132132130@c.us",
+  "text": "Hi there!",
+  "session": "default"
+}
+```
+
+Also, you can use `curl` and send POST request like this:
 
 ```bash
 # Phone without +
-# Using GET
-curl "http://localhost:3000/api/sendText?phone=79776772457&text=Hello+from+WhatsApp+HTTP+API+Free!"
-
-# Using POST 
-export PHONE=79776772457
-curl -d "{\"chatId\": \"${PHONE}@c.us\", \"text\": \"Hello from WhatsApp HTTP API Free\" }" -H "Content-Type: application/json" -X POST http://localhost:3000/api/sendText
+export PHONE=12132132130
+curl -d "{\"chatId\": \"${PHONE}@c.us\", \"text\": \"Hello from WhatsApp HTTP API\" }" -H "Content-Type: application/json" -X POST http://localhost:3000/api/sendText
 ```
 
-# Receive messages
-
-To show how to receive messages we'll create a simple "echo" server with two functions:
-
-1. When we receive a text message - just send the text back
-2. When we receive a message with a file (an image, a voice message) - download it and send the path back
-
-In order to send you messages we use **Webhooks** (look at them below) and configure them via environments variables. So
-what you need to
-create "echo" server is HTTP server that will receive JSON POST request and then call back WhatsApp HTTP API
-via `POST /api/sendText` endpoint with JSON body.
-
-### Python echo server
-
-We use Python. Feel free to create your favorite language example and contribute to the project!
-
-Run "echo" server in one terminal and leave it working:
-
-```bash
-# if you haven't already
-git clone https://github.com/allburov/whatsapp-http-api.git 
-cd whatsapp-http-api
-python -mpip install -r examples/requirements.txt
-export FLASK_APP=examples/echo.py
-flask run
-```
-
-Visit http://localhost:5000 and check that we are good to go further.
-
-Let's start WhatsApp HTTP API and configure the "on message" webhook and point it on our "http://localhost:5000/message"
-endpoint:
-
-```bash
-docker run -it -v `pwd`/tokens:/app/tokens --network=host -e WHATSAPP_HOOK_ONMESSAGE=http://localhost:5000/message allburov/whatsapp-http-api
-```
-
-Now go ahead, open the second whatsapp and send to our WhatsApp HTTP API a text message! It must reply the same text.
-
-If you try to send an image the "echo server" will send a path to the downloaded file.
-
-# Environment variables
-
-## Common
-
-- `DEBUG` - show debug and verbose logs, set in any value
-- `WHATSAPP_API_PORT` - listen port for HTTP server (default: `3000`)
-- `WHATSAPP_API_HOSTNAME` - Hostname for HTTP server (default: `localhost`)
-
-## Webhooks
-
-The description of [webhooks you can in Venom README.md, section Events](https://github.com/orkestral/venom#events)
-
-All webhooks are disabled by default:
-
-- `WHATSAPP_HOOK_ONMESSAGE=http://localhost/uri`
-- `WHATSAPP_HOOK_ONSTATECHANGE=http://localhost/uri`
-- `WHATSAPP_HOOK_ONACK=http://localhost/uri`
-- `WHATSAPP_HOOK_ONADDEDTOGROUP=http://localhost/uri`
-
-## File storage
-
-- `WHATSAPP_FILES_FOLDER` - folder where will be stored files from chats (images, voice messages) (
-  default: `/tmp/whatsapp-files`)
-- `WHATSAPP_FILES_MIMETYPES` - download only these mimetypes from messages (download all files be default). Mimetypes
-  must be separated by a comma, without spaces: `audio,image/png,image/gif`. In order to choose type use prefix (
-  like `audio,image`).
-- `WHATSAPP_FILES_LIFETIME`- to keep free space files will be removed after this time (default: `180`, in seconds)
-
-# Support
-
-If you want to support the project - you can either:
-
-1. Create a Pull Request for desired functionality
-2. Support [the project one time, every month or get access to telegram channel on Boosty](https://boosty.to/allburov)

+# WAHA (WhatsApp HTTP API) Python examples
+
+## Installation
+
+We assume that you have installed software:
+
+1. Python 3
+2. Docker
+
+### Download and start image
+
+First of all, you must run WhatsApp HTTP API locally (which under the hood it
+runs real WhatsApp Web instance and expose HTTP API for interaction).
+
+Here are the steps from
+[Quick Start](https://waha.devlike.pro/docs/overview/quick-start/):
+
+Download and start WhatsApp HTTP API docker container
+
+```bash
+# Download the image
+docker pull devlikeapro/waha
+# Run the docker container
+docker run -it --rm --network=host -e WHATSAPP_HOOK_URL=http://localhost:5000/bot -e "WHATSAPP_HOOK_EVENTS=*" --name waha devlikeapro/waha
+
+# It prints logs and the last line must be
+# WhatsApp HTTP API is running on: http://[::1]:3000
+```
+
+#### Download image - ARM
+
+If you're using ARM (like Apple Silicon, Apple M1, etc.) - use following
+commands to download the image
+
+![](/images/versions/core.png) For Core version the command is
+
+```bash
+# Download the image
+docker pull devlikeapro/waha:arm
+# Rename it, so you can use devlikeapro/waha image in other place
+docker tag devlikeapro/waha:arm devlikeapro/waha
+# Run the docker container
+docker run -it --rm --network=host -e WHATSAPP_HOOK_URL=http://localhost:5000/bot -e "WHATSAPP_HOOK_EVENTS=*" --name waha devlikeapro/waha
+
+# It prints logs and the last line must be
+# WhatsApp HTTP API is running on: http://[::1]:3000
+```
+
+### Start session and scan QR
+
+2. Open Swagger API in the browser http://localhost:3000/
+3. Start session and scan QR code in swagger
+   1. Find `POST /api/session/start` request press **Try it out** and
+      **Execute** it with `default` session name
+   2. Find `GET /api/screenshot` and execute it - it must show QR code
+   3. Scan QR code on your mobile WhatsApp application (that installed on your
+      phone)
+   4. Execute `GET /api/screenshot` once again - it must show the screenshot
+      from WhatsApp Web.
+4. Send test text message - find `POST /api/sendText` and execute it with
+   payload (change `12132132130` in the `chatId` to phone number that is
+   registered in WhatsApp).
+
+```json
+{
+  "chatId": "12132132130@c.us",
+  "text": "Hi there!",
+  "session": "default"
+}
+```
+
+If you see **Hi there!** message then you're ready to run bots!
+
+## WhatsApp Echo Bot
+
+The WhatsApp Echo Bot is a sample flask webhook server application that echoes
+back to you whatever you send it. It can serve as a basic reference for how to
+set up webhooks and reply to incoming messages.
+
+```bash
+# Clone the git repository with example
+git clone https://github.com/devlikeapro/waha.git
+# Open python example folder
+cd waha/examples/python
+# Install requirements
+python -mpip install -r requirements.txt
+# Run the bot
+FLASK_APP=whatsapp_echo_bot.py flask run
+```
+
+Open http://127.0.0.1:5000/bot - if you see **WhatsApp Echo Bot is ready!** then
+the bot is ready to receive message!
+
+Send message to the WhatsApp (that you used to scan QR code) and it'll echo text
+back to you!
+
+## WhatsApp Download Files Bot
+
+The WhatsApp Download Image Bot downloads all files people send to your WhatsApp
+and log the path for the file.
+
+**The bot works only with WAHA Plus version** available with donations. Visit
+[read more about difference between Core and Plus versions](https://waha.devlike.pro/docs/how-to/plus-version/).
+
+Download **WAHA Plus** version:
+
+```bash
+# Download the image
+docker pull devlikeapro/waha-plus
+# Run the docker container
+docker run -it --rm --network=host -e WHATSAPP_HOOK_URL=http://localhost:5000/bot -e "WHATSAPP_HOOK_EVENTS=*" --name waha devlikeapro/waha-plus
+```
+
+Run the WhatsApp Download Files bot:
+
+```bash
+# Clone the git repository with example
+git clone https://github.com/devlikeapro/waha.git
+# Open python example folder
+cd waha/examples/python
+# Install requirements
+python -mpip install -r requirements.txt
+# Run the bot
+FLASK_APP=whatsapp_download_files_bot.py flask run
+```
+
+Open http://127.0.0.1:5000/bot - if you see **WhatsApp Download Files Bot!**
+then the bot is ready to receive message with files!
