+This bot can be easily deployed using Docker.
+
+## **Requirements**
+To run this project in a Docker container you must have Docker and Docker Compose installed in your machine. Find how to install Docker in your machine [here](https://docs.docker.com/get-docker/) and find how to install Docker Compose in your machine [here](https://docs.docker.com/compose/install/).
+
+Once you have Docker and Docker Compose installed in your machine, clone or download this repository and follow the instructions below.
+
+## **Running the Bot**
+To run the bot in a Docker container, you must first create a `.env` file in the root of the project if there isn't one already. You will need to change the parameters in the `.env` file to your own parameters. You can find an example of a `.env` file [here](.env.example). You will also be able to change the settings in that environment file as explained in the [Settings page](.github/Docs/SETTINGS.md). 
+
+**If any of the following commands fail, try without a dash between docker and compose.**
+
+To run the bot, simply execute the following command in the root of the project:
+```bash
+docker-compose up -d
+```
+This will build the Docker image and run the bot in a Docker container. The `-d` flag is used to run the container in detached mode, which means that the container will run in the background. If you want to see the logs of the container, you can run the following command:
+```bash
+docker-compose logs -f
+```
+
+To stop the container, run the following command:
+```bash
+docker-compose down
+```
+## **Updating the Bot**
+To update the bot, you must first stop the container as explained in the previous section. Then, you must pull the latest changes from the repository, in any way you want. Finally, you must build the Docker image again and run the container again. To do this, run the following commands:
+```bash
+docker-compose build
+docker-compose up -d
+```

+
+> 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 .env file or in an environment variable.
+Here is a sample of the .env file:
+
+```env
+BOT_TOKEN=Your_Own_Bot_Token
+SPOTIFY_ID=Your_Own_Spotify_ID
+SPOTIFY_SECRET=Your_Own_Spotify_Secret
+BOT_PREFIX=Your_Wanted_Prefix_For_Vulkan
+SHOULD_AUTO_DISCONNECT_WHEN_ALONE=True #all settings can be set like this
+#etc... All settings can be set this way
+```
+
+
+### **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 in the .env file or in an environment variable to what 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 in the .env file or in an environment variable 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 in the .env file or in an environment variable 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 in the .env file or in an environment variable 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 in the .env file or in an environment variable to what you want to.

-#  **Music**
-- Play musics from Youtube, Spotify and Deezer links (Albums, Artists, Playlists and Tracks)
-- Control loop of one or all musics
-- Allow moving and removing musics in the queue
-- Play musics in queue randomly
-- Store played songs and allow bidirectional flow

 ### **.Env File Example**
 This is an example of how your .env file (located in root) should look like.
-```
+```env
 BOT_TOKEN=Your_Own_Bot_Token
 SPOTIFY_ID=Your_Own_Spotify_ID
 SPOTIFY_SECRET=Your_Own_Spotify_Secret
 BOT_PREFIX=Your_Wanted_Prefix_For_Vulkan

+SHOULD_AUTO_DISCONNECT_WHEN_ALONE=True #all settings can be set like this
+#etc... All settings can be set this way
 ```
 
-### **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 bot's configuration is stored in the [.env](.env) file, you can change the prefix and the bot token there, as well as all the other configurations.
+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 🌟
+
+### **🐳 Docker**
+You can also run this project in a Docker container. You can find the instructions to run this project in a Docker container in the [Docker Instructions](.github/Docs/DOCKER.md) page.
 
 
-## **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

-## Testing
+## **🚀 Heroku (Not free anymore)**
+> *Heroku doesn't offer free host services anymore.* <br>
+
+To deploy and run your Bot in Heroku 24/7, follow the instructions in the [Heroku Instructions](.github/Docs/HEROKU.md) page.
+
+## 🧪 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>
