## Before Starting

1. Make sure you set up your domain by following this documentation: [Dendrite Domain Name Setup](https://element-hq.github.io/dendrite/installation/domainname).

2. Ensure you have `docker` and `docker compose` installed on your server.

3. All commands will be executed in the project root, i.e., the directory where the repository was cloned.

## Installation

1. Clone this repository and enter the directory:

```sh
git clone https://gitlab.com/rogs/dendrite-docker-bridges.git
cd dendrite-docker-bridges
```

2. Run `setup.sh`:

```sh
./setup.sh
```

This script will:
- Prompt you for your domain (the one you configured in "Before Starting")
- Generate a secure database password
- Create your private key and config in the `./config/dendrite` directory
- Display two important pieces of information:
  - The "Registration shared secret"
  - The Database URI

**Important**: Make sure to save both the registration shared secret AND the Database URI in a secure location. The Database URI will be needed later when configuring the bridges for WhatsApp, Telegram, and Discord.

3. Open your configuration file located at `./config/dendrite/dendrite.yaml`. **You may need `sudo` to edit this file.** Search for `registration_shared_secret` and paste the registration secret you copied in the previous step. The section should look similar to this:

```yaml
client_api:
  registration_disabled: true
  registration_requires_token: false
  registration_shared_secret: "YourBigCopiedKey123" # This is your key!
  guests_disabled: false
  enable_registration_captcha: false
  recaptcha_api_js_url: ""
```

4. Start Dendrite (only the DB and the monolith!):

```sh
docker compose up -d postgres monolith
```

5. Run `setup-db.sh`:

```sh
./setup-db.sh
```

This script will create three new databases: `whatsapp`, `telegram`, and `discord`. These will be used later for the bridges.

6. Verify the setup by navigating to `http://your-ip-address:8008` in your browser. You should see a screen similar to this:

7. Create your first user using the provided script:

```sh
./create-user.sh
```

The script will:
- Prompt you for a username
- Ask if the user should be an admin
- Create the account in your Dendrite server

You can run this script multiple times to create additional users as needed.

## That's It!

Dendrite is now up and running! You can proceed with setting up the bridges:

- [WhatsApp Bridge](./config/mautrix-whatsapp/README.md)
- [Telegram Bridge](./config/mautrix-telegram/README.md)
- [Discord Bridge](./config/mautrix-discord/README.md)

**Note**: When configuring each bridge, you'll need to use the Database URI that was displayed during the setup process. Make sure you have saved it somewhere secure!
