 # Setting up Appservices
 ## Getting help
 If you run into any problems while setting up an Appservice, 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).
 ## Tested appservices
 Here are some appservices we tested and that work with Conduit:
 - matrix-appservice-discord
 - mautrix-hangouts
 - mautrix-telegram
 ## Set up the appservice
 Follow whatever instructions are given by the appservice. This usually includes
 downloading, changing its config (setting domain, homeserver url, port etc.)
 and later starting it.
 At some point the appservice guide should ask you to add a registration yaml
 file to the homeserver. In Synapse you would do this by adding the path to the
 homeserver.yaml, but in Conduit you can do this from within Matrix:
 First, go into the #admins room of your homeserver. The first person that
 registered on the homeserver automatically joins it. Then send a message into
 the room like this:
    @conduit:your.server.name: register_appservice
    ```
    paste
    the
    contents
    of
    the
    yaml
    registration
    here
    ```
 You can confirm it worked by sending a message like this:
 `@conduit:your.server.name: list_appservices`
 The @conduit bot should answer with `Appservices (1): your-bridge`
 Then you are done. Conduit will send messages to the appservices and the
 appservice can send requests to the homeserver. You don't need to restart
 Conduit, but if it doesn't work, restarting while the appservice is running
 could help.

 ##### Deploy using a Debian package
 You need to have the `deb` helper command installed that creates Debian packages from Cargo projects (see [cargo-deb](https://github.com/mmstick/cargo-deb/) for more info):
 ```shell
 $ cargo install cargo-deb
 ```
 Then, you can create and install a Debian package at a whim:
 ```shell
 $ cargo deb
 $ dpkg -i target/debian/matrix-conduit_0.1.0_amd64.deb
 ```
 This will build, package, install, configure and start Conduit. [Read more](debian/README.Debian).
 Note that `cargo deb` supports [cross-compilation](https://github.com/mmstick/cargo-deb/#cross-compilation) too!
 Official Debian packages will follow once Conduit starts to have stable releases.
 ##### Deploy using Docker
 Pull and run the docker image with
 ``` bash
 docker pull matrixconduit/matrix-conduit:latest
-docker run -d -p 8448:8000 -v ~/conduit.toml:/srv/conduit/conduit.toml -v db:/srv/conduit/.local/share/conduit matrixconduit/matrix-conduit:latest

+For detached mode, you also need to use the `-d` flag. You can pass in more env vars as are shown here, for an overview of possible values, you can take a look at the `docker-compose.yml` file.
 You can pass in different env vars to change config values on the fly. You can even configure Conduit completely by using env vars, but for that you need
 too pass `-e CONDUIT_CONFIG=""` into your container. For an overview of possible values, please take a look at the `docker-compose.yml` file.
 If you just want to test Conduit for a short time, you can use the `--rm` flag, which will clean up everything related to your container after you stop it.
