-### Thanks rms
 
-Huge thanks to Richard Stallman for using LibreX and featuring it on his [website](https://stallman.org/stallman-computing.html)!
+### About LibreY
 
-> However, the Librex proxies have worked around that problem. They enable me to access Google Search indirectly, and they work correctly through Tor with LibreJS enabled.
+LibreY gives you text results from DuckDuckGo or Google, images from Qwant, and torrents from i.e. Ahmia and popular torrent sites without spying on you.
+<br>LibreY doesn't save **any** type of data about the user, there are no logs (except NGINX logs if the host sets them).

+### Running a docker container
+
+Dockerized librey is a way to provide users with yet another way to self-host their own projects with a view to privacy. If you wish to help, please start by looking for bugs in used docker configurations.
+
+### Running a Docker container through ghcr
+
+To run librey in a docker container, you can simply use the command:
+
+```sh
+docker run -d \
+  --name librey \
+  -e TZ="America/New_York" \
+  -e CONFIG_GOOGLE_DOMAIN="com" \
+  -e CONFIG_GOOGLE_LANGUAGE="en" \
+  -e CONFIG_WIKIPEDIA_LANGUAGE="en" \
+  -p 8080:8080 \
+  ghcr.io/ahwxorg/librey:latest
+```
+
+Also run with watchtower for auto-updating: (optional)
+```sh
+docker run -d \
+  --name librey-watchtower-1 \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  containrrr/watchtower
+```
+
+<br>
+
+### Running a Docker container with composer
+
+```yml

+
+### Environment variables that can be set in the Docker container

+<br>
+
+### Docker version issues
+
+If you are going to build your own docker image based on this repository, pay attention to your Docker version, because depending on how recent the installed version is, maybe you should use the `buildx` command instead of `build`.
+
+Docker <= 20.10: `docker build`
+
+Docker > 20.10: `docker buildx build`
+
+<br>
+
+### Building a docker image
+
+If you don't want to use the image that is already available on `docker hub`, then you can simply build the Dockerfile directly from the github repository using the command:
+
+```sh
+docker build https://github.com/Ahwxorg/librey.git -t librey:latest
+```
+
+```sh
+docker run -d --name librey \
+    -e CONFIG_GOOGLE_DOMAIN="com" \
+    -e CONFIG_GOOGLE_LANGUAGE="en" \
+    -p 8080:8080 \
+    librey:latest
+```
+
+Or, instead of doing the build remotely, you still have the opportunity to `git clone` the repository, and build it locally with the command:
+
+```sh
+git clone https://github.com/Ahwxorg/librey.git
+cd librey/
+docker build -t librey:latest .
+```
+
+<br>
+
+### Support for different architectures
+
+Supported architectures for the official librey images include the same ones supported by Alpine itself, which are typically denoted as `linux/386`, `linux/amd64`, `linux/arm/v6`. If you need support for a different architecture, such as `linux/arm/v7`, you can modify the 'Dockerfile' to use a more comprehensive base image like `ubuntu:latest` instead.
+
+In this case, you must run the `buildx` process specifying the desired architecture as shown in the example below:
+
+```sh
+docker buildx build \
+    --no-cache \
+    --platform linux/arm/v7 \
+    --tag ahwxorg/librey:latest .
+```
+
+**OBS:** Keep in mind that this can cause some issues at build time, so you need to know a little about Dockerfiles to solve this problem for your specific case.

+		<p style='text-align: center;'>Oh and also, the LibreY maintainers list all the instances in the instances.json (Highly unfriendly) file instead of the README.md. There is only 4 instances listed in the README.md file and they are the "official" ones backed by the LibreY maintaners. So people will just use those instances and not the other ones hosted by the community. Poop to be honest</p>
