 ## Getting help

-If you run into any problems while setting up Conduit, write an email to `timo@koesters.xyz`, ask us in `#conduit:matrix.org` or [open an issue on GitLab](https://gitlab.com/famedly/conduit/-/issues/new).
+If you run into any problems while setting up Conduit, write an email to `timo@koesters.xyz`, ask us
+in `#conduit:matrix.org` or [open an issue on GitLab](https://gitlab.com/famedly/conduit/-/issues/new).

 ## Installing Conduit

+Although you might be able to compile Conduit for Windows, we do recommend running it on a linux server. We therefore
+only offer Linux binaries.
+
 You may simply download the binary that fits your machine. Run `uname -m` to see what you need. Now copy the right url:

 ## Docker

 ### Build & Dockerfile

 The Dockerfile provided by Conduit has two stages, each of which creates an image.
+
 1. **Builder:** Builds the binary from local context or by cloning a git revision from the official repository.
-2. **Runtime:** Copies the built binary from **Builder** and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.
-
-The Dockerfile includes a few build arguments that should be supplied when building it.
-
-``` Dockerfile
-ARG LOCAL=false
-ARG CREATED
-ARG VERSION
-ARG GIT_REF=origin/master
-```
-
- **CREATED:** Date and time as string (date-time as defined by RFC 3339). Will be used to create the Open Container Initiative compliant label `org.opencontainers.image.created`. Supply by it like this `$(date -u +'%Y-%m-%dT%H:%M:%SZ')`
- **VERSION:** The SemVer version of Conduit, which is in the image. Will be used to create the Open Container Initiative compliant label `org.opencontainers.image.version`. If you have a `Cargo.toml` in your build context, you can get it with `$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml)`
- **LOCAL:** *(Optional)* A boolean value, specifies if the local build context should be used, or if the official repository will be cloned. If not supplied with the build command, it will default to `false`.
- **GIT_REF:** *(Optional)* A git ref, like `HEAD` or a commit ID. The supplied ref will be used to create the Open Container Initiative compliant label `org.opencontainers.image.revision` and will be the ref that is cloned from the repository when not building from the local context. If not supplied with the build command, it will default to `origin/master`.
+2. **Runner:** Copies the built binary from **Builder** and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.

 To build the image you can use the following command

-``` bash
-docker build . -t matrixconduit/matrix-conduit:latest --build-arg CREATED=$(date -u +'%Y-%m-%dT%H:%M:%SZ') --build-arg VERSION=$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml)
+```bash
+docker build --tag matrixconduit/matrix-conduit:latest .
 ```

 which also will tag the resulting image as `matrixconduit/matrix-conduit:latest`.
-**Note:** it ommits the two optional `build-arg`s.
-

 ### Run

 After building the image you can simply run it with

-``` bash
+```bash
 docker run -d -p 8448:6167 -v ~/conduit.toml:/srv/conduit/conduit.toml -v db:/srv/conduit/.local/share/conduit matrixconduit/matrix-conduit:latest
 ```

 or you can skip the build step and pull the image from one of the following registries:

 | Registry        | Image                                                           | Size                  |

-
 ## Docker-compose

 If the docker command is not for you or your setup, you can also use one of the provided `docker-compose` files. Depending on your proxy setup, use the [`docker-compose.traefik.yml`](docker-compose.traefik.yml) and [`docker-compose.override.traefik.yml`](docker-compose.override.traefik.yml) for Traefik (don't forget to remove `.traefik` from the filenames) or the normal [`docker-compose.yml`](../docker-compose.yml) for every other reverse proxy. Additional info about deploying
 Conduit can be found [here](../DEPLOY.md).

-
 ### Build

 To build the Conduit image with docker-compose, you first need to open and modify the `docker-compose.yml` file. There you need to comment the `image:` option and uncomment the `build:` option. Then call docker-compose with:

-``` bash
-CREATED=$(date -u +'%Y-%m-%dT%H:%M:%SZ') VERSION=$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml) docker-compose up
