# Setting up Buscarron (optional)
The playbook can install and configure [buscarron ](https://gitlab.com/etke.cc/buscarron ) for you.
It's a bot you can use to setup **your own helpdesk on matrix**
It's a bot you can use to send any form (HTTP POST, HTML) to a (encrypted) matrix room
## Registering the bot user
By default, the playbook will set up the bot with a username like this: `@bot.buscarron:DOMAIN` .
(to use a different username, adjust the `matrix_bot_buscarron_login` variable).
You **need to register the bot user manually** before setting up the bot. You can use the playbook to [register a new user ](registering-users.md ):
```
ansible-playbook -i inventory/hosts setup.yml --extra-vars='username=bot.buscarron password=PASSWORD_FOR_THE_BOT admin=no' --tags=register-user
```
Choose a strong password for the bot. You can generate a good password with a command like this: `pwgen -s 64 1` .
## Adjusting the playbook configuration
Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file:
```yaml
matrix_bot_buscarron_enabled: true
# Adjust this to whatever password you chose when registering the bot user
matrix_bot_buscarron_password: PASSWORD_FOR_THE_BOT
# Adjust accepted forms
matrix_bot_buscarron_forms:
- name: contact # (mandatory) Your form name, will be used as endpoint, eg: buscarron.DOMAIN/contact
room: "!yourRoomID:DOMAIN" # (mandatory) Room ID where form submission will be posted
redirect: https://DOMAIN # (mandatory) To what page user will be redirected after the form submission
ratelimit: 1r/m # (optional) rate limit of the form, format: < max requests > r/< interval:s , m > , eg: 1r/s or 54r/m
hasemail: 1 # (optional) form has "email" field that should be validated
extensions: [] # (optional) list of form extensions (not used yet)
matrix_bot_buscarron_spamlist: [] # (optional) list of emails/domains/hosts (with wildcards support) that should be rejected automatically
```
You will also need to add a DNS record so that buscarron can be accessed.
By default buscarron will use https://buscarron.DOMAIN so you will need to create an CNAME record for `buscarron` .
See [Configuring DNS ](configuring-dns.md ).
If you would like to use a different domain, add the following to your configuration file (changing it to use your preferred domain):
```yaml
matrix_server_fqn_buscarron: "form.{{ matrix_domain }}"
```
## Installing
After configuring the playbook, run the [installation ](installing.md ) command again:
```
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
```
## Usage
To use the bot, invite the `@bot.buscarron:DOMAIN` to the room you specified in a config, after that any point your form to the form url, example for the `contact` form:
```html
< form method = "POST" action = "https://buscarron.DOMAIN/contact" >
<!-- your fields -->
< / form >
```
