 ### Installing
 
-First, download the [latest release](https://github.com/Tzahi12345/YoutubeDL-Material/releases/latest)!
+1. First, download the [latest release](https://github.com/Tzahi12345/YoutubeDL-Material/releases/latest)!
 
-Drag all the files in `youtubedl-material` to a location accessible to a web server. It works best if it's the root (usually right inside `public_html`. Once that's done, navigate to `backend` and edit the `default.json` file. If you're using SSL encryption, look at the `encrypted.json` file for a template. 
+2. Drag the `youtubedl-material` directory to an easily accessible directory. Navigate to the `config` folder and edit the `default.json` file. If you're using SSL encryption, look at the `encrypted.json` file for a template.
 
-Port forward `17442` if you're going to access YoutubeDL-Material from out of your network. This is an important step. Make sure the configuration reflects this appropriately.
+NOTE: If you are intending to use a reverse proxy, this next step is not necessary
+3. Port forward the port listed in `default.json`, which defaults to `17442`.
 
-Once the configuration is done, type `sudo nodejs app.js`. This will run the backend server. On your browser, navigate to your installation folder. Try putting in a youtube link to see if it works. If it does, viola! YoutubeDL-Material is now up and running.
+4. Once the configuration is done, run `npm install` to install all the backend dependencies. Once that is finished, type `nodejs app.js`. This will run the backend server, which serves the frontend as well. On your browser, navigate to to the server (url with the specified port). Try putting in a youtube link to see if it works. If it does, viola! YoutubeDL-Material is now up and running.
 
 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
 
+NOTE: If you are using YoutubeDL-Material v3.2 or lower, click [here](https://github.com/Tzahi12345/YoutubeDL-Material/blob/b87a9f1e2fd896b8e3b2f12429b7ffb15ea4521b/README.md#configuration) for the old README

 To deploy, simply clone the repository, and go into the `youtubedl-material` directory. Type `npm install` and all the dependencies will install. Then type `cd backend` and again type `npm install` to install the dependencies for the backend.
 
-Once you do that, you're almost up and running. All you need to do is edit the configuration in `youtubedl-material/backend/config`, go back into the `youtubedl-material` directory, and type `ng build --prod`. This will build the app, and put the output files in the `youtubedl-material/dist` folder. Drag those files into a web server, and drag the `backend` directory into the same folder. This folder should have `index.html` in it as well. If it does **not**, you're in the wrong directory.

+
+## 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 -L 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. The default options will work, however, and point to `http://localhost:8998`. You can find an explanation of these configuration items in [Configuration](#Configuration) section. 
+3. Run `docker-compose pull`. This will download the official YoutubeDL-Material docker image.
+4. Run `docker-compose up` to start it up. If successful, it should say "HTTP(S): Started on port 8998" or something similar. 
+5. Make sure you can connect to the specified URL + port, and if so, you are done!
+
+## API
+
+You can use the internal API on your server to run downloads on your instance without using the frontend. All of the available endpoints can be seen over [here](https://github.com/Tzahi12345/YoutubeDL-Material/blob/master/backend/app.js) -- search for '/api/' on the page to find all the endpoints. I will expand on the available endpoints in the future, but for now I'd like to highlight the two most useful ones:
+
+#### Downloading audio files 
+`curl -XPOST -H "Content-type: application/json" -d '{"url": "<your youtube url>"}' 'http://localhost:17442/api/tomp3'`
+
+Remember to replace `<your video url>` with the actual URL. 
+
+#### Downloading video files
+`curl -XPOST -H "Content-type: application/json" -d '{"url": "<your youtube url>"}' 'http://localhost:17442/api/tomp4'`
+
+Remember to replace `<your video url>` with the actual URL.
