# Configuration
**Conduit** is configured using a TOML file. The configuration file is loaded from the path specified by the `CONDUIT_CONFIG` environment variable.
> **Note:** The configuration file is required to run Conduit. If the `CONDUIT_CONFIG` environment variable is not set, Conduit will exit with an error.
> **Note:** If you update the configuration file, you must restart Conduit for the changes to take effect
Conduit's configuration file is divided into the following sections:
- [Global](#global)
- [TLS](#tls)
- [Proxy](#proxy)
## Global
The `global` section contains the following fields:

### TLS
The `tls` table contains the following fields:
- `certs`: The path to the public PEM certificate
- `key`: The path to the PEM private key
#### Example
```toml
[global.tls]
certs = "/path/to/cert.pem"
key = "/path/to/key.pem"
```
### Proxy
You can choose what requests conduit should proxy (if any). The `proxy` table contains the following fields
#### Global
The global option will proxy all outgoing requests. The `global` table contains the following fields:
- `url`: The URL of the proxy server
##### Example
```toml
[global.proxy.global]
url = "https://example.com"
```
#### By domain
An array of tables that contain the following fields:
- `url`: The URL of the proxy server
- `include`: Domains that should be proxied (assumed to be `["*"]` if unset)
- `exclude`: Domains that should not be proxied (takes precedent over `include`)
Both `include` and `exclude` allow for glob pattern matching.
##### Example
In this example, all requests to domains ending in `.onion` and `matrix.secretly-an-onion-domain.xyz`
will be proxied via `socks://localhost:9050`, except for domains ending in `.myspecial.onion`. You can add as many `by_domain` tables as you need.
```toml
[[global.proxy.by_domain]]
url = "socks5://localhost:9050"
include = ["*.onion", "matrix.secretly-an-onion-domain.xyz"]
exclude = ["*.clearnet.onion"]
```
### Example
> **Note:** The following example is a minimal configuration file. You should replace the values with your own.
```toml
[global]
{{#include ../conduit-example.toml:22:}}
```
