# Setting up ChatGPT (optional)
The playbook can install and configure [matrix-chatgpt-bot ](https://github.com/matrixgpt/matrix-chatgpt-bot ) for you.
Talk to [ChatGPT ](https://openai.com/blog/chatgpt/ ) via your favourite Matrix client!
## 1. Register the bot account
The playbook does not automatically create users for you. The bot requires an access token to be able to connect to your homeserver.
You **need to register the bot user manually** before setting up the bot.
Choose a strong password for the bot. You can generate a good password with a command like this: `pwgen -s 64 1` .
You can use the playbook to [register a new user ](registering-users.md ):
```
ansible-playbook -i inventory/hosts setup.yml --extra-vars='username=bot.chatgpt password=PASSWORD_FOR_THE_BOT admin=no' --tags=register-user
```
## 2. Get an access token
Refer to the documentation on [how to obtain an access token ](obtaining-access-tokens.md ).
## 3. Adjusting the playbook configuration
Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file (adapt to your needs):
```yaml
matrix_bot_chatgpt_enabled: true
# See instructions on
# https://www.npmjs.com/package/chatgpt
matrix_bot_chatgpt_openai_email: ''
matrix_bot_chatgpt_openai_password: ''
matrix_bot_chatgpt_openai_login_type: google
# This is the default username
# matrix_bot_chatgpt_matrix_bot_username_localpart: 'bot.chatgpt'
# Matrix access token (from bot user above)
# see: https://webapps.stackexchange.com/questions/131056/how-to-get-an-access-token-for-element-riot-matrix
matrix_bot_chatgpt_matrix_access_token: ''
```
You will need to get tokens for ChatGPT.
## 4. Installing
After configuring the playbook, run the [installation ](installing.md ) command again:
```sh
ansible-playbook -i inventory/hosts setup.yml --tags=install-all,start
```
## Usage
To use the bot, invite the `@bot.chatgpt:DOMAIN` to the room you specified in a config, after that start speaking to it, use the prefix if you configured one or mention the bot.
You can also refer to the upstream [documentation ](https://github.com/matrixgpt/matrix-chatgpt-bot ).
