## Running
|
||||||
|
|
||||||
|
Once you've built Velocity, you can copy and run the `-all` JAR from
|
||||||
|
`proxy/build/libs`. Velocity will generate a default configuration file
|
||||||
|
and you can configure it from there.
|
||||||
|
|
||||||
|
Alternatively, you can get the proxy JAR from the [downloads](https://www.velocitypowered.com/downloads)
|
||||||
|
page.
