+Material you will find pretty much all the crucial information
+here that we need in most cases!)

 ## Build it yourself
 
 If you'd like to install YoutubeDL-Material, go to the Installation section. If you want to build it yourself and/or develop the repository, then this section is for you.
 
 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/appdata`, 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 the `public` directory in the `backend` folder.

+### Host-specific instructions
+
+If you're on a Synology NAS, unRAID, Raspberry Pi 4 or any other possible special case you can check if there's known issues or instructions both in the issue tracker and in the [Wiki!](https://github.com/Tzahi12345/YoutubeDL-Material/wiki#environment-specific-guideshelp)
+
+### 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/youtubedl-material-docker.zip -o youtubedl-material-docker.zip` to download the latest Docker zip release, or go to the [releases](https://github.com/Tzahi12345/YoutubeDL-Material/releases/) page to grab the version you'd like.
-2. Unzip the `youtubedl-material-docker.zip` and navigate into the root folder.
-3. Modify the config items in the `appdata` folder 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. 
-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 8998" or something similar. 
-6. Make sure you can connect to the specified URL + port, and if so, you are done!
+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 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!
+
+### 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:
+
+```yml
+environment:
+    UID: YOUR_UID
+    GID: YOUR_GID
+```
+
+## MongoDB
+
+For much better scaling with large datasets please run your YoutubeDL-Material instance with 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)!

 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.
 
+## iOS Shortcut 
+
+If you are using iOS, try YoutubeDL-Material more conveniently with a Shortcut. With this Shorcut, you can easily start downloading YouTube video with just two taps! (Or maybe three?)
+
+You can download Shortcut [here.](https://routinehub.co/shortcut/10283/)
+
 ## Contributing
 
-Feel free to submit a pull request! I have no guidelines as of yet, so no need to worry about that.
+If you're interested in contributing, first: awesome! Second, please refer to the guidelines/setup information located in the [Contributing](https://github.com/Tzahi12345/YoutubeDL-Material/wiki/Contributing) wiki page, it's a helpful way to get you on your feet and coding away.
+
+Pull requests are always appreciated! If you're a bit rusty with coding, that's no problem: we can always help you learn. And if that's too scary, that's OK too! You can create issues for features you'd like to see or bugs you encounter, it all helps this project grow.

+## Reporting a Vulnerability
+
+Please file an issue in our GitHub's repo, because this app
+isn't meant to be safe to run as public instance yet, but rather as a LAN facing app.
+
+We welcome PRs and help in general in making YTDL-M more secure, but it's not a priority as of now.

+Categories:
+
+    Categories are a way to organize videos based on dynamic rules set by the user. Categories are universal (so not per-user).
+    
+    Categories, besides rules, have an optional custom output. This custom output can help users create their
+        desired directory structure.
+
+Rules:
+    A category rule consists of a property, a comparison, and a value. For example, "uploader includes 'VEVO'"
+
+    Rules are stored as an object with the above fields. In addition to those fields, it also has a preceding_operator, which
+        is either OR or AND, and signifies whether the rule should be ANDed with the previous rules, or just ORed. For the first
+        rule, this field is null.
+
+    Ex. (title includes 'Rihanna' OR title includes 'Beyonce' AND uploader includes 'VEVO')

-    "Derivative Works" shall mean any work, whether in Source or Object
-    form, that is based on (or derived from) the Work and for which the

-    worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-    copyright license to reproduce, prepare Derivative Works of,

-    as of the date such litigation is filed.

-        the Derivative Works; and
-
-    (d) If the Work includes a "NOTICE" text file as part of its
-        distribution, then any Derivative Works that You distribute must
-        include a readable copy of the attribution notices contained

-        wherever such third-party notices normally appear. The contents
-        of the NOTICE file are for informational purposes only and

-        notices within Derivative Works that You distribute, alongside

-    the terms of any separate license agreement you may have executed
-    with Licensor regarding such Contributions.
-
- 6. Trademarks. This License does not grant permission to use the trade
-    names, trademarks, service marks, or product names of the Licensor,
-    except as required for reasonable and customary use in describing the
-    origin of the Work and reproducing the content of the NOTICE file.
-
- 7. Disclaimer of Warranty. Unless required by applicable law or
-    agreed to in writing, Licensor provides the Work (and each
-    Contributor provides its Contributions) on an "AS IS" BASIS,
-    WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-    implied, including, without limitation, any warranties or conditions
-    of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-    PARTICULAR PURPOSE. You are solely responsible for determining the
-    appropriateness of using or redistributing the Work and assume any
-    risks associated with Your exercise of permissions under this License.
-
- 8. Limitation of Liability. In no event and under no legal theory,
-    whether in tort (including negligence), contract, or otherwise,
-    unless required by applicable law (such as deliberate and grossly

-    liable to You for damages, including any direct, indirect, special,
-    incidental, or consequential damages of any character arising as a
-    result of this License or out of the use or inability to use the
-    Work (including but not limited to damages for loss of goodwill,
-    work stoppage, computer failure or malfunction, or any and all
-    other commercial damages or losses), even if such Contributor
-    has been advised of the possibility of such damages.
-
- 9. Accepting Warranty or Additional Liability. While redistributing
-    the Work or Derivative Works thereof, You may choose to offer,
-    and charge a fee for, acceptance of support, warranty, indemnity,
-    or other liability obligations and/or rights consistent with this
-    License. However, in accepting such obligations, You may act only
-    on Your own behalf and on Your sole responsibility, not on behalf
-    of any other Contributor, and only if You agree to indemnify,
-    defend, and hold each Contributor harmless for any liability
-    incurred by, or claims asserted against, such Contributor by reason
-    of your accepting any such warranty or additional liability.
