# Configuring Capsul-Flask
Create a `.env` file to set up the application configuration:
```
nano .env
```
You can enter any environment variables referenced in [`__init__.py`](../capsulflask/__init__.py) to this file.
For example you may enter your SMTP credentials like this:
```
MAIL_USERNAME=forest@nullhex.com
MAIL_DEFAULT_SENDER=forest@nullhex.com
MAIL_PASSWORD=**************
```
## <a name="example"></a>Example configuration from capsul.org (production):
```
#LOG_LEVEL=DEBUG
BASE_URL="https://capsul.org"
# hub url is used by the SPOKE_MODE to contact the hub. Since this server is the hub,
# this is fine. In fact it runs into problems (routing related?) when I set it to capsul.org.
# similarly the baikal "spoke" (set up in the hosts table in the db) has "http://localhost:5000" as the https_url
HUB_URL="http://localhost:5000"
HUB_MODE_ENABLED="t"
SPOKE_MODE_ENABLED="t"
HUB_MODEL="capsul-flask"
SPOKE_MODEL="shell-scripts"
SPOKE_HOST_ID="baikal"
SPOKE_HOST_TOKEN="<redacted>"
HUB_TOKEN="<redacted>"
# smtp.. see https://flask-mail.readthedocs.io/en/latest/#configuring-flask-mail
MAIL_SERVER="smtp.nullhex.com"
# MAIL_USE_SSL means SMTP with STARTTLS
MAIL_USE_SSL=true
# MAIL_USE_TLS means SMTP wrapped in TLS
MAIL_USE_TLS=false
MAIL_PORT="465"
MAIL_USERNAME="capsul@nullhex.com"
