### Calling asynchronous methods
Some methods, such as `dew.command`, will need to communicate with the game in order to operate.
Because JavaScript code is executed in a separate process, these methods will immediately return a `Promise` that will be fulfilled once the operation completes.
If you aren't familiar with promises, here is very a basic skeleton for you to use:
dew.methodName(arguments).then(function (result) {
// This will be called once the method completes.
// result is the value returned by the method.
}).catch(function (error) {
// This will be called if an error occurs.
// If you don't care to handle errors, then there is no need to use catch().
### Running console commands
**Do not use RCON to run console commands. It is slow, unreliable, and the protocol is subject to change in the future.**

### Getting the ElDewrito version
Since all communications with ElDewrito are asynchronous, you have to call the getVersion function with a success callback:
You can use `dew.getVersion` to get the current version of ElDewrito. Remember that this runs asynchronously.
dew.getVersion(function (version) {
dew.getVersion().then(function (version) {
