## Configuration
Copy `serves3.toml.example` to `serves3.toml` from this project's sources and adjust your settings. If the project was built and installed via CMake, a copy of the example settings file is in `/usr/share/doc/serves3`.
Copy `Settings.toml.example` to `Settings.toml` and adjust your settings.
For instance:
```toml
# apply this configuration to Rocket's "default" profile

# the bucket name
name = ""
# the API endpoint address
endpoint = "https://eu-central-1.linodeobjects.com"

You can also use the same file to customize the server options. See the [Rocket documentation](https://rocket.rs/v0.5-rc/guide/configuration/#rockettoml) for a list of understood values.
You can also add a `Rocket.toml` file to customize the server options. See the [Rocket documentation](https://rocket.rs/v0.5-rc/guide/configuration/#rockettoml).

# Changelog
## 1.1.0 Reworked configuration file logic
* **Breaking change**: configuration file renamed to `serves3.toml`. Please note that the format changed slightly; have a look at the provided `serves3.toml.example` file for reference.
* Fixes #2: URLs to directories not ending with a slash are not redirected properly
## 1.0.0
* Initial release.
