+# 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).
+
+## Set up the appservice - general instructions
+
+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.
+
+## Appservice-specific instructions
+
+### Tested appservices
+
+These appservices have been tested and work with Conduit without any extra steps:

+### [mautrix-signal](https://github.com/mautrix/signal)
+
+There are a few things you need to do, in order for the Signal bridge (at least
+up to version `0.2.0`) to work. How you do this depends on whether you use
+Docker or `virtualenv` to run it. In either case you need to modify
+[portal.py](https://github.com/mautrix/signal/blob/master/mautrix_signal/portal.py).
+Do this **before** following the bridge installation guide.
+
+1. **Create a copy of `portal.py`**. Go to
+   [portal.py](https://github.com/mautrix/signal/blob/master/mautrix_signal/portal.py)
+at [mautrix-signal](https://github.com/mautrix/signal) (make sure you change to
+the correct commit/version of mautrix-signal you're using) and copy its
+content. Create a new `portal.py` on your system and paste the content in.
+2. **Patch the copy**. Exact line numbers may be slightly different, look nearby if they don't match: 
+  - [Line 1020](https://github.com/mautrix/signal/blob/4ea831536f154aba6419d13292479eb383ea3308/mautrix_signal/portal.py#L1020)
+    ```diff
+    --- levels.users[self.main_intent.mxid] = 9001 if is_initial else 100
+    +++ levels.users[self.main_intent.mxid] = 100 if is_initial else 100
+    ```
+  - [Between lines 1041 and 1042](https://github.com/mautrix/signal/blob/4ea831536f154aba6419d13292479eb383ea3308/mautrix_signal/portal.py#L1041-L1042) add a new line:
+    ```diff
+        "type": str(EventType.ROOM_POWER_LEVELS),
+    +++ "state_key": "",
+        "content": power_levels.serialize(),
+    ```
+3. **Deploy the patch**. This is different depending on how you have `mautrix-signal` deployed:
+  - [*If using virtualenv*] Copy your patched `portal.py` to `./lib/python3.7/site-packages/mautrix_signal/portal.py` (the exact version of Python may be different on your system).
+  -  [*If using Docker*] Map the patched `portal.py` into the `mautrix-signal` container:
+    
+    ```yaml
+    volumes:
+      - ./your/path/on/host/portal.py:/usr/lib/python3.9/site-packages/mautrix_signal/portal.py
+    ```
+4. Now continue with the [bridge installation instructions ](https://docs.mau.fi/bridges/index.html) and the general bridge notes above.

+# Deploying Conduit
+
+## 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).
+
+## 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:
+
+| CPU Architecture                            | Download stable version        |
+| ------------------------------------------- | ------------------------------ |
+| x84_64 / amd64 (Most servers and computers) | [Download][x84_64-musl-master] |
+| armv6                                       | [Download][armv6-musl-master]  |
+| armv7 (e.g. Raspberry Pi by default)        | [Download][armv7-musl-master]  |
+| armv8 / aarch64                             | [Download][armv8-musl-master]  |
+
+[x84_64-musl-master]: https://gitlab.com/famedly/conduit/-/jobs/artifacts/master/raw/conduit-x86_64-unknown-linux-musl?job=build:release:cargo:x86_64-unknown-linux-musl
+[armv6-musl-master]: https://gitlab.com/famedly/conduit/-/jobs/artifacts/master/raw/conduit-arm-unknown-linux-musleabihf?job=build:release:cargo:arm-unknown-linux-musleabihf
+[armv7-musl-master]: https://gitlab.com/famedly/conduit/-/jobs/artifacts/master/raw/conduit-armv7-unknown-linux-musleabihf?job=build:release:cargo:armv7-unknown-linux-musleabihf
+[armv8-musl-master]: https://gitlab.com/famedly/conduit/-/jobs/artifacts/master/raw/conduit-aarch64-unknown-linux-musl?job=build:release:cargo:aarch64-unknown-linux-musl
+
+```bash
+$ sudo wget -O /usr/local/bin/matrix-conduit <url>
+$ sudo chmod +x /usr/local/bin/matrix-conduit
+```
+
+Alternatively, you may compile the binary yourself using
+
+```bash
+$ cargo build --release
+```
+
+Note that this currently requires Rust 1.50.
+
+If you want to cross compile Conduit to another architecture, read the [Cross-Compile Guide](CROSS_COMPILE.md).
+
+## Adding a Conduit user
+
+While Conduit can run as any user it is usually better to use dedicated users for different services. This also allows
+you to make sure that the file permissions are correctly set up.
+
+In Debian you can use this command to create a Conduit user:
+
+```bash
+sudo adduser --system conduit --no-create-home
+```
+
+## Setting up a systemd service
+
+Now we'll set up a systemd service for Conduit, so it's easy to start/stop Conduit and set it to autostart when your
+server reboots. Simply paste the default systemd service you can find below into
+`/etc/systemd/system/conduit.service`.
+
+```systemd
+[Unit]
+Description=Conduit Matrix Server
+After=network.target
+
+[Service]
+Environment="CONDUIT_CONFIG=/etc/matrix-conduit/conduit.toml"
+User=conduit
+Group=nogroup
+Restart=always
+ExecStart=/usr/local/bin/matrix-conduit
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Finally, run
+
+```bash
+$ sudo systemctl daemon-reload
+```
+
+## Creating the Conduit configuration file
+
+Now we need to create the Conduit's config file in `/etc/matrix-conduit/conduit.toml`. Paste this in **and take a moment
+to read it. You need to change at least the server name.**
+
+```toml
+[global]
+# The server_name is the name of this server. It is used as a suffix for user
+# and room ids. Examples: matrix.org, conduit.rs
+# The Conduit server needs to be reachable at https://your.server.name/ on port
+# 443 (client-server) and 8448 (federation) OR you can create /.well-known
+# files to redirect requests. See
+# https://matrix.org/docs/spec/client_server/latest#get-well-known-matrix-client
+# and https://matrix.org/docs/spec/server_server/r0.1.4#get-well-known-matrix-server
+# for more information
+
+# YOU NEED TO EDIT THIS
+#server_name = "your.server.name"
+
+# This is the only directory where Conduit will save its data
+database_path = "/var/lib/matrix-conduit/conduit_db"
+
+# The port Conduit will be running on. You need to set up a reverse proxy in
+# your web server (e.g. apache or nginx), so all requests to /_matrix on port
+# 443 and 8448 will be forwarded to the Conduit instance running on this port
+port = 6167
+
+# Max size for uploads
+max_request_size = 20_000_000 # in bytes
+
+# Enables registration. If set to false, no users can register on this server.
+allow_registration = true
+
+# Disable encryption, so no new encrypted rooms can be created
+# Note: existing rooms will continue to work
+allow_encryption = true
+allow_federation = true
+
+trusted_servers = ["matrix.org"]
+
+#max_concurrent_requests = 100 # How many requests Conduit sends to other servers at the same time
+#workers = 4 # default: cpu core count * 2
+
+address = "127.0.0.1" # This makes sure Conduit can only be reached using the reverse proxy
+
+# The total amount of memory that the database will use.
+#db_cache_capacity_mb = 200
+```
+
+## Setting the correct file permissions
+
+As we are using a Conduit specific user we need to allow it to read the config. To do that you can run this command on
+Debian:
+
+```bash
+sudo chown -R conduit:nogroup /etc/matrix-conduit
+```
+
+If you use the default database path you also need to run this:
+
+```bash
+sudo mkdir -p /var/lib/matrix-conduit/conduit_db
+sudo chown -R conduit:nogroup /var/lib/matrix-conduit/conduit_db
+```
+
+## Setting up the Reverse Proxy
+
+This depends on whether you use Apache, Nginx or another web server.
+
+### Apache
+
+Create `/etc/apache2/sites-enabled/050-conduit.conf` and copy-and-paste this:
+
+```apache
+Listen 8448
+
+<VirtualHost *:443 *:8448>
+
+ServerName your.server.name # EDIT THIS
+
+AllowEncodedSlashes NoDecode
+ProxyPass /_matrix/ http://127.0.0.1:6167/_matrix/ nocanon
+ProxyPassReverse /_matrix/ http://127.0.0.1:6167/_matrix/
+
+</VirtualHost>
+```
+
+**You need to make some edits again.** When you are done, run
+
+```bash
+$ sudo systemctl reload apache2
+```
+
+### Nginx
+
+If you use Nginx and not Apache, add the following server section inside the http section of `/etc/nginx/nginx.conf`
+
+```nginx
+server {
+    listen 443 ssl http2;
+    listen [::]:443 ssl http2;
+    listen 8448 ssl http2;
+    listen [::]:8448 ssl http2;
+    server_name your.server.name; # EDIT THIS
+    merge_slashes off;
+
+    location /_matrix/ {
+        proxy_pass http://127.0.0.1:6167$request_uri;
+        proxy_set_header Host $http_host;
+        proxy_buffering off;
+    }
+
+    ssl_certificate /etc/letsencrypt/live/your.server.name/fullchain.pem; # EDIT THIS
+    ssl_certificate_key /etc/letsencrypt/live/your.server.name/privkey.pem; # EDIT THIS
+    ssl_trusted_certificate /etc/letsencrypt/live/your.server.name/chain.pem; # EDIT THIS
+    include /etc/letsencrypt/options-ssl-nginx.conf;
+}
+```
+
+**You need to make some edits again.** When you are done, run
+
+```bash
+$ sudo systemctl reload nginx
+```
+
+## SSL Certificate
+
+The easiest way to get an SSL certificate, if you don't have one already, is to install `certbot` and run this:
+
+```bash
+$ sudo certbot -d your.server.name
+```
+
+## You're done!
+
+Now you can start Conduit with:
+
+```bash
+$ sudo systemctl start conduit
+```
+
+Set it to start automatically when your system boots with:
+
+```bash
+$ sudo systemctl enable conduit
+```
+
+## How do I know it works?
+
+You can open <https://app.element.io>, enter your homeserver and try to register.
+
+You can also use these commands as a quick health check.
+
+```bash
+$ curl https://your.server.name/_matrix/client/versions
+$ curl https://your.server.name:8448/_matrix/client/versions
+```
+
+If you want to set up an appservice, take a look at the [Appservice Guide](APPSERVICES.md).

 # Conduit
 ### A Matrix homeserver written in Rust

-[![Matrix](https://img.shields.io/matrix/conduit:conduit.rs?server_fqdn=conduit.koesters.xyz)](https://matrix.to/#/#conduit:matrix.org)
-
 #### What is the goal?

+An efficient Matrix homeserver that's easy to set up and just works. You can install
 it on a mini-computer like the Raspberry Pi to host Matrix for your family,
 friends or company.
 
+
 #### Can I try it out?
 
-Yes! Just open a Matrix client (<https://app.element.io> or Element Android for
-example) and register on the `https://conduit.koesters.xyz` homeserver.
+Yes! You can test our Conduit instance by opening a Matrix client (<https://app.element.io> or Element Android for
+example) and registering on the `conduit.rs` homeserver.
+
+It is hosted on a ODROID HC 2 with 2GB RAM and a SAMSUNG Exynos 5422 CPU, which
+was used in the Samsung Galaxy S5. It joined many big rooms including Matrix
+HQ.
+
+
+#### What is the current status?
+
+As of 2021-09-01, Conduit is Beta, meaning you can join and participate in most
+Matrix rooms, but not all features are supported and you might run into bugs
+from time to time.
+
+There are still a few important features missing:
+
+- E2EE verification over federation
+- Outgoing read receipts, typing, presence over federation
+
+Check out the [Conduit 1.0 Release Milestone](https://gitlab.com/famedly/conduit/-/milestones/3).
+
 
 #### How can I deploy my own?
 
-##### From source
+Simple install (this was tested the most): [DEPLOY.md](DEPLOY.md)\
+Debian package: [debian/README.Debian](debian/README.Debian)\
+Docker: [docker/README.md](docker/README.md)
 
-Clone the repo, build it with `cargo build --release` and call the binary
-(target/release/conduit) from somewhere like a systemd script. [Read
-more](DEPLOY_FROM_SOURCE.md)
+If you want to connect an Appservice to Conduit, take a look at [APPSERVICES.md](APPSERVICES.md).
 
-##### Using Docker
-
-Pull and run the docker image with
-
-``` bash
-docker pull matrixconduit/matrix-conduit:latest
-docker run -d -p 8448:8000 -v db:/srv/conduit/.local/share/conduit matrixconduit/matrix-conduit:latest
-```
-
-Or build and run it with docker or docker-compose. [Read more](docker/README.md)
-
-#### What is it build on?
-
-- [Ruma](https://www.ruma.io): Useful structures for endpoint requests and
-  responses that can be (de)serialized
-- [Sled](https://github.com/spacejam/sled): A simple (key, value) database with
-  good performance
-- [Rocket](https://rocket.rs): A flexible web framework
-
-#### What are the biggest things still missing?
-
-- Appservices (Bridges and Bots)
-- Most federation features (invites, e2ee)
-- Push notifications on mobile
-- Notification settings
-- Lots of testing
-
-Also check out the [milestones](https://git.koesters.xyz/timo/conduit/milestones).
 
 #### How can I contribute?
 
 1. Look for an issue you would like to work on and make sure it's not assigned
    to other users
 2. Ask someone to assign the issue to you (comment on the issue or chat in
-   #conduit:matrix.org)
-3. Fork the repo and work on the issue. #conduit:matrix.org is happy to help :)
-4. Submit a PR
+   #conduit:nordgedanken.dev)
+3. Fork the repo and work on the issue. #conduit:nordgedanken.dev is happy to help :)
+4. Submit a MR

+Conduit for Debian
+==================
+
+Configuration
+-------------
+
+When installed, Debconf generates the configuration of the homeserver
+(host)name, the address and port it listens on. This configuration ends up in
+/etc/matrix-conduit/conduit.toml.
+
+You can tweak more detailed settings by uncommenting and setting the variables
+in /etc/matrix-conduit/conduit.toml. This involves settings such as the maximum
+file size for download/upload, enabling federation, etc.
+
+Running
+-------
+
+The package uses the matrix-conduit.service systemd unit file to start and
+stop Conduit. It loads the configuration file mentioned above to set up the
+environment before running the server.
+
+This package assumes by default that Conduit will be placed behind a reverse
+proxy such as Apache or nginx. This default deployment entails just listening
+on 127.0.0.1 and the free port 6167 and is reachable via a client using the URL
+http://localhost:6167.
+
+At a later stage this packaging may support also setting up TLS and running
+stand-alone.  In this case, however, you need to set up some certificates and
+renewal, for it to work properly.

 ### 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

-- **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 `HEAD`.
+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
-docker run -d -p 8448:8000 -v db:/srv/conduit/.local/share/conduit -e ROCKET_SERVER_NAME="localhost:8000" matrixconduit/matrix-conduit:latest
+```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
 ```
 
-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.
-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.
+or you can skip the build step and pull the image from one of the following registries:
 
+| Registry        | Image                                                           | Size                  |
+| --------------- | --------------------------------------------------------------- | --------------------- |
+| Docker Hub      | [matrixconduit/matrix-conduit:latest][dh]                       | ![Image Size][shield] |
+| GitLab Registry | [registry.gitlab.com/famedly/conduit/matrix-conduit:latest][gl] | ![Image Size][shield] |

+[gl]: https://gitlab.com/famedly/conduit/container_registry/
+[shield]: https://img.shields.io/docker/image-size/matrixconduit/matrix-conduit/latest
+
+The `-d` flag lets the container run in detached mode. You now need to supply a `conduit.toml` config file, an example can be found [here](../conduit-example.toml).
+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
+to 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.
 
 ## 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) including [`docker-compose.override.traefik.yml`](docker-compose.override.traefik.yml) or the normal [`docker-compose.yml`](../docker-compose.yml) for every other reverse proxy.

+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
+```bash
+docker-compose up
 ```
 
-This will also start the container right afterwards, so if want it to run in detached mode, you also should use the `-d` flag. For possible `build-args`, please take a look at the above `Build & Dockerfile` section.

+
+### Use Traefik as Proxy
+
+As a container user, you probably know about Traefik. It is a easy to use reverse proxy for making containerized app and services available through the web. With the
+two provided files, [`docker-compose.traefik.yml`](docker-compose.traefik.yml) and [`docker-compose.override.traefik.yml`](docker-compose.override.traefik.yml), it is
+equally easy to deploy and use Conduit, with a little caveat. If you already took a look at the files, then you should have seen the `well-known` service, and that is
+the little caveat. Traefik is simply a proxy and loadbalancer and is not able to serve any kind of content, but for Conduit to federate, we need to either expose ports
+`443` and `8448` or serve two endpoints `.well-known/matrix/client` and `.well-known/matrix/server`.
+
+With the service `well-known` we use a single `nginx` container that will serve those two files.
+
+So...step by step:
+
+1. Copy [`docker-compose.traefik.yml`](docker-compose.traefik.yml) and [`docker-compose.override.traefik.yml`](docker-compose.override.traefik.yml) from the repository and remove `.traefik` from the filenames.
+2. Open both files and modify/adjust them to your needs. Meaning, change the `CONDUIT_SERVER_NAME` and the volume host mappings according to your needs.
+3. Create the `conduit.toml` config file, an example can be found [here](../conduit-example.toml), or set `CONDUIT_CONFIG=""` and configure Conduit per env vars.
+4. Uncomment the `element-web` service if you want to host your own Element Web Client and create a `element_config.json`.
+5. Create the files needed by the `well-known` service.
+
+   - `./nginx/matrix.conf` (relative to the compose file, you can change this, but then also need to change the volume mapping)
+
+     ```nginx
+     server {
+         server_name <SUBDOMAIN>.<DOMAIN>;
+         listen      80 default_server;
+
+         location /.well-known/matrix/ {
+             root /var/www;
+             default_type application/json;
+             add_header Access-Control-Allow-Origin *;
+         }
+     }
+     ```
+
+   - `./nginx/www/.well-known/matrix/client` (relative to the compose file, you can change this, but then also need to change the volume mapping)
+     ```json
+     {
+       "m.homeserver": {
+         "base_url": "https://<SUBDOMAIN>.<DOMAIN>"
+       }
+     }
+     ```
+   - `./nginx/www/.well-known/matrix/server` (relative to the compose file, you can change this, but then also need to change the volume mapping)
+     ```json
+     {
+       "m.server": "<SUBDOMAIN>.<DOMAIN>:443"
+     }
+     ```
+
+6. Run `docker-compose up -d`
+7. Connect to your homeserver with your preferred client and create a user. You should do this immediatly after starting Conduit, because the first created user is the admin.
