 If you experience problems, know that it's usually caused by a configuration problem. The first thing you should do is check the console. To get there, right click anywhere on the page and click "Inspect element." Then on the menu that pops up, click console. Look at the error there, and try to investigate.
 
+### Configuration
+
+Here is an explanation for the configuration entries. Check out the [default config](https://github.com/Tzahi12345/YoutubeDL-Material/blob/master/backend/config/default.json) for more context.
+
+| Config item | Description | Default |
+| ------------- | ------------- | ------------- |
+| frontendurl  | URL to the webserver hosting YTDL-Material | "http://example.com" |
+| backendurl  | URL to the YTDL-Material's backend, should include port 17442 | "http://example.com:17442/" |
+| use-encryption | true if you intend to use SSL encryption (https) | false |
+| cert-file-path | Cert file path - required if using encryption | "/etc/letsencrypt/live/example.com/fullchain.pem" |
+| key-file-path | Private key file path - required if using encryption |  "/etc/letsencrypt/live/example.com/privkey.pem" |
+| path-base | Audio/video stream URL. Usually the same as backendurl | "http://example.com:17442/" |
+| path-audio | Path to audio folder for saved mp3s | "audio/" |
+| path-video | Path to video folder for saved mp4s | "video/" |
+| title_top | Title shown on the top toolbar | "Youtube Downloader" |
+| file_manager_enabled | true if you want to use the file manager | true |
+| allow_quality_select | true if you want to select a videos quality level before downloading | true |
+| download_only_mode | true if you want files to directly download to the client with no media player | false |
+| use_youtube_API | true if you want to use the Youtube API which is used for YT searches | false |
+| youtube_API_key | Youtube API key. Required if use_youtube_API is enabled | "" |
+| default_theme | Default theme to use. Options are "default" and "dark" | "default" |
+| allow_theme_change | true if you want the icon in the top toolbar that toggles dark mode | true |

 Finally, port forward the port `17442` and point it to the server's IP address. Make sure the port is also allowed through the firewall.
 
+## Docker
+
+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 https://github.com/Tzahi12345/YoutubeDL-Material/releases/latest/download/docker-compose.yml -o docker-compose.yml` to download the latest release of `docker-compose.yml`, or go to the [releases](https://github.com/Tzahi12345/YoutubeDL-Material/releases/) page to grab the version you'd like.
+2. Modify the config items in the `environment` section of `docker-compose.yml` to your liking. Otherwise, the default options will work and point to `http://localhost:8998`. You can find an explanation of these configuration items in [Configuration](#Configuration) section. 
+3. Make sure the port in the `frontend_url` environment variable lines up with the port in the `ports` section.
+4. Run `docker-compose pull`. This will download the official YoutubeDL-Material docker image.
+5. Run `docker-compose up` to start it up. If successful, it should say "HTTP(S): Started on port 17442" or something similar. Make sure you can connect to the frontend, and if so, you are done!
