# Settings
!!! info "Settings generator tool"
To help you tune BunkerWeb, we have made an easy-to-use settings generator tool available at [config.bunkerweb.io](https://config.bunkerweb.io/?utm_campaign=self&utm_source=doc).
This section contains the full list of settings supported by BunkerWeb. If you are not yet familiar with BunkerWeb, you should first read the [concepts](concepts.md) section of the documentation. Please follow the instructions for your own [integration](integrations.md) on how to apply the settings.
As a general rule when multisite mode is enabled, if you want to apply settings with multisite context to a specific server, you will need to add the primary (first) server name as a prefix like `www.example.com_USE_ANTIBOT=captcha` or `myapp.example.com_USE_GZIP=yes` for example.
When settings are considered as "multiple", it means that you can have multiple groups of settings for the same feature by adding numbers as suffix like `REVERSE_PROXY_URL_1=/subdir`, `REVERSE_PROXY_HOST_1=http://myhost1`, `REVERSE_PROXY_URL_2=/anotherdir`, `REVERSE_PROXY_HOST_2=http://myhost2`, ... for example.
