+**Describe the bug**
+A clear and concise description of what the bug is.
+
+**To Reproduce**
+Steps to reproduce the behavior:
+1. Go to '...'
+2. Click on '....'
+3. Scroll down to '....'
+4. See error
+
+**Expected behavior**
+A clear and concise description of what you expected to happen.
+
+**Screenshots**
+If applicable, add screenshots to help explain your problem.
+
+**Environment**
+- YoutubeDL-Material version
+- Docker tag: <tag> (optional)

+Ideally you'd copy the info as presented on the "About" dialogue
+in YoutubeDL-Material.
+(for that, click on the three dots on the top right and then
+check "installation details". On later versions of YoutubeDL-
+Material you will find pretty much all the crucial information
+here that we need in most cases!)
+
+**Additional context**
+Add any other context about the problem here. For example, a YouTube link.

+### USAGE OF THE NIGHTLY BUILDS IS HIGHLY RECOMMENDED.
+
+For much better scaling with large datasets please run your YTDL-M instance with a MongoDB backend rather than the json file-based default.
+It will fix a lot of performance problems (especially with datasets in the tens of thousands videos/audios)!
+The (closed) issues as well as the project's Wiki will give you good starting points for your journey!
+
+For MongoDB specifically there is [this little guide](https://github.com/Tzahi12345/YoutubeDL-Material/wiki/Setting-a-MongoDB-backend-to-use-as-database-provider-for-YTDL-M).

 ### Prerequisites
 
 NOTE: If you would like to use Docker, you can skip down to the [Docker](#Docker) section for a setup guide.
 
-Make sure you have these dependencies installed on your system: nodejs and youtube-dl. If you don't, run this command:
+Debian/Ubuntu:
 
+```bash
+sudo apt-get install nodejs youtube-dl ffmpeg unzip python npm
 ```
-sudo apt-get install nodejs youtube-dl

+CentOS 7:
+
+```bash
+sudo yum install epel-release
+sudo yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm
+sudo yum install centos-release-scl-rh
+sudo yum install rh-nodejs12
+scl enable rh-nodejs12 bash

 ### Setup
 
 If you are looking to setup YoutubeDL-Material with Docker, this section is for you. And you're in luck! Docker setup is quite simple.
 
 1. Run `curl -L https://github.com/Tzahi12345/YoutubeDL-Material/releases/latest/download/docker-compose.yml -o docker-compose.yml` to download the latest Docker Compose, or go to the [releases](https://github.com/Tzahi12345/YoutubeDL-Material/releases/) page to grab the version you'd like.
 2. Run `docker-compose pull`. This will download the official YoutubeDL-Material docker image.
-3. Run `docker-compose up` to start it up. If successful, it should say "HTTP(S): Started on port 8998" or something similar.
-4. Make sure you can connect to the specified URL + port, and if so, you are done!
+3. Run `docker-compose up` to start it up. If successful, it should say "HTTP(S): Started on port 17443" or something similar. This tells you the *container-internal* port of the application. Please check your `docker-compose.yml` file for the *external* port. If you downloaded the file as described above, it defaults to **8998**.
+4. Make sure you can connect to the specified URL + *external* port, and if so, you are done!
+
+NOTE: It is currently recommended that you use the `nightly` tag on Docker. To do so, simply update the docker-compose.yml `image` field so that it points to `tzahi12345/youtubedl-material:nightly`.
 
 ### Custom UID/GID
 
 By default, the Docker container runs as non-root with UID=1000 and GID=1000. To set this to your own UID/GID, simply update the `environment` section in your `docker-compose.yml` like so:
 
-```

+[API Docs](https://youtubedl-material.stoplight.io/docs/youtubedl-material/Public%20API%20v1.yaml)
 
 To get started, go to the settings menu and enable the public API from the *Extra* tab. You can generate an API key if one is missing.
 
 Once you have enabled the API and have the key, you can start sending requests by adding the query param `apiKey=API_KEY`. Replace `API_KEY` with your actual API key, and you should be good to go! Nearly all of the backend should be at your disposal. View available endpoints in the link above.

+## Supported Versions

+4.2's RELEASE build is now quite old and should be considered legacy.
+We urge users to use the nightly releases, because the project

+## Reporting a Vulnerability
+
+Please file an issue in our GitHub's repo, because this app

+Rules:

+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.

+# This is the chart version. This version number should be incremented each time you make changes

+# Versions are expected to follow Semantic Versioning (https://semver.org/)
