+> Heroku doesn't offer free services anymore 
+
+Nobody wants to run the Vulkan process on their machine, so we host the process on Heroku, <s>a cloud platform that contains free</s>.<br>
+To configure the Vulkan to run in your Heroku account you will need to:
+
+- Create an application project in Heroku.
+- Configure the environment variables in your application.
+- Add these buildpacks to your application:
+    
+    ```
+    - heroku/python
+    - https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git
+    - https://github.com/xrisk/heroku-opus.git
+    ```
+    The order shown above is exactly the upside-down order that Buildpacks should appear in Heroku.
+- Set the heroku stack to be `heroku-20`. <br>
+    As shown in this issue: [Issue](https://github.com/RafaelSolVargas/Vulkan/issues/25) the heroku-buildpack doesn't work properly with the heroku application Stack set as above `heroku-20`.
+
+<br>
+
+This [Youtube Video](https://www.youtube.com/watch?v=BPvg9bndP1U&ab_channel=TechWithTim) shows the process of hosting a Bot in Heroku.
+
+You can also fork this project and set in Heroku to your application automatically deploy when your project receive a new commit, and then control when new versions of Vulkan become available to your Bot.

+## Important Parameters
+- Bot Prefix
+- Auto Disconnect When Alone
+- Specific Process for each Player
+- Maximum songs downloading at a time
+- Maximum songs in a Queue Page
+
+All parameters can be modified in the Configs.py file that are located in the Config folder
+> The path to the file is ./Config/Configs.py
+
+
+### **Bot Prefix**
+The Bot Prefix is just a string that must be passed as prefix when calling any Bot command from the Discord.
+To change that you must: <br> 
+- Change the property BOT_PREFIX of the VConfigs class to what prefix you want to. 
+
+### **Auto Disconnect**
+As a result of the [Issue 33](https://github.com/RafaelSolVargas/Vulkan/issues/33) you can configure if the Bot will auto disconnect when being alone in the voice channel. The default configuration is to disconnect within 300 seconds if it finds out no one is currently listing to it.
+To change that you must: <br> 
+- Change the property SHOULD_AUTO_DISCONNECT_WHEN_ALONE of the VConfigs class to False 
+
+### **Multiprocessing or Threading**
+As a result of the [Issue 35](https://github.com/RafaelSolVargas/Vulkan/issues/35) you can configure if the Bot will create a specific Python Process for each Player (Guild) that he is playing songs or all will happen in the Main Process. The Default behavior is to create a new process.
+To change that you must: <br> 
+- Change the property SONG_PLAYBACK_IN_SEPARATE_PROCESS of the VConfigs class to False 
+
+### **Maximum Downloading Quant**
+The download of songs can be very fast or very slow, the faster it is the slower the response time for any command (during the download) is higher, (including the playback quality), because there will be a Task for each song. But it's possible to set up this variable to slow the download and keep the response time better. 
+To change that you must: <br> 
+- Change the property MAX_DOWNLOAD_SONGS_AT_A_TIME of the VConfigs class to what you want to. 
+
+### **Maximum Songs In Queue Page**
+When the ```Queue``` command is called, the current song playlist is presented in the Discord, you can configure how many songs you will want to show in each page.
+To change that you must: <br> 
+- Change the property MAX_SONGS_IN_PAGE of the VConfigs class to what you want to.

-# **Vulkan**
-
-A multi-purpose Discord bot, including music, written in Python and supports Youtube and Spotify sources for playing. Vulkan was designed so that everyone could fork this project and use it, including a 24/7 host on Heroku.
+<h1 align="center">Vulkan</h1> 
 
 
-Vulkan is also able to get data from Warframe and send it to users, get random phrases and handle random operations to help users decide what to do.
+A Music Discord Bot, that plays *Youtube*, *Spotify*, *Deezer* links or raw queries. Vulkan is open source, so everyone can fork this project, follow the instructions and use it in their own way, executing it in your own machine or hosting in others machines to work 24/7.
+
+Vulkan uses multiprocessing and asynchronous Python modules to maximize Music Player response time, so the player doesn't lag when many commands are being processed and it can play in multiples discord serves at the same time without affecting the Music Player response time.
 
 
-## **Prerequisites:** 
+<p align="center">
+  <img src="./Assets/playermenu.jpg" />
+</p>
 
-### **API Keys**
+
+#  **Music 🎧**
+- Play musics from Youtube, Spotify and Deezer links (Albums, Artists, Playlists and Tracks).
+- Play musics in multiple discord server at the same time.
+- The player contains buttons to shortcut some commands. 
+- Support for the new Discord Slash commands.
+- Search for all musics in Queue using buttons.
+- Shortcut the playing of one song using dropdown menu.
+- Manage the loop of one or all playing musics.
+- Manage the order and remove musics from the queue.
+- Shuffle the musics queue order.
+- Automatically clean the sended messages so it doesn't fill up your server.

+## **Setting up for yourself** 
+
+
+### **Requirements**
+Installation of ``Python 3.10+`` and the dependencies in the requirements.txt file, creation of your own Bot in Discord and Spotify Keys. <br>
+To install the dependencies type this command in the terminal, in the project root folder.
+ 
+```
+pip install -r requirements.txt
+```
+### **🔑 API Keys**
+You have to create your own discord Bot and store your Bot Token 
  * Your Discord Application - [Discord](https://discord.com/developers)
  * You own Spotify Keys - [Spotify](https://developer.spotify.com/dashboard/applications)
 
     - This information must be stored in an .env file, explained further.
 
-### **Requirements**
-- Installation of Python 3.8+ and the dependencies in the requirements.txt file.
-```
-pip install -r requirements.txt
-```
+###  **Installation of FFMPEG**<br>
+FFMPEG is a module that will be used to play music, you must have this configured in your machine
+*FFMPEG must be configured in the PATH for Windows users. Check this [YoutubeVideo](https://www.youtube.com/watch?v=r1AtmY-RMyQ&t=114s&ab_channel=TroubleChute).* <br><br>
+You can download the executables in this link `https://www.ffmpeg.org/download.html` and then put the .exe files inside a ffmpeg\bin folder in your C:\ folder. Do not forget to add 'ffmpeg\bin' to your PATH.

 ```
 
-### **Config File**
-The config file, located in ```./config``` folder doesn't require any change, but if you acquire the knowledged of how it works, you can change it to the way you want.
+### **⚙️ Configs**
+The config file is located at ```./config/Configs.py```, it doesn't require any change, but if you can change the values to the way you want. <br>
+Take a look in the [Settings page](.github/Docs/SETTINGS.md) to personalize the Bot for you.
 
 
 ### **Initialization**
 - Go to [Discord](https://discord.com/developers) and invite your Bot to your own server
 - Run ```python main.py``` in console to start
+- Give this project a nice 🌟
 
 
-## **Heroku**
-To run your Bot in Heroku 24/7, you will need the Procfile located in root, then follow the instructions in this [video](https://www.youtube.com/watch?v=BPvg9bndP1U&ab_channel=TechWithTim). In addition, also add these two buildpacks to your Heroku Application:
-
-    - https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git
-
-    - https://github.com/xrisk/heroku-opus.git
+<br>
+<hr>
+<br>
 
 
-#  **Music**
-- Play musics from Youtube and Spotify Playlists
-- Controll loop of one or all musics
-- Allow realocating musics in the queue
-- Play musics in queue randomly
+## **🚀 Heroku (Not free anymore)**
+> *Heroku doesn't offer free host services anymore.* <br>
 
-### Commands
-```!play [title, spotify_url, youtube_url]``` - Start playing song in Discord
+To deploy and run your Bot in Heroku 24/7, follow the instructions in the [Heroku Instructions](.github/Docs/HEROKU.md) page.
 
-```!resume``` - Resume the song player
-
-```!pause``` - Pause the song player
-
-```!move [x, y]``` - Change the musics in position x and y in Queue
-
-```!skip``` - Skip the currently playing song
-
-```!stop``` - Stop the playing of musics
-
-```!queue``` - Show the musics list in queue
-
-```!shuffle``` - Shuffle the songs in queue
-
-```!remove [x]``` - Remove the song in position x
-
-```!reset``` - Reset the player, recommended if any error happen 
-
-```!loop [one, all, off]``` - Control the loop of songs 
-
-```!np``` - Show information of the currently song 
-
-```!clear``` - Clear the songs in queue, doesn't stop the player 
+## 🧪 Tests
+The tests were written manually with no package due to problems with async function in other packages, to execute them type in root: <br>
+`python run_tests.py`<br>
