# Add Your Own Builtins
As discussed in the [Node]() section, some service functionalities have ubiquitous demand making them suitable candidates to be directly deployed to a peer node. The [Aqua distributed hash table](https://github.com/fluencelabs/fluence/tree/master/deploy/builtins/aqua-dht) \(DHT\) is an example of builtin service. The remainder of this tutorial guides you through the steps necessary to create and deploy a Builtin service.

# Setting Up Your Environment
In order to develop within the Fluence solution, [Node](https://nodejs.org/en/), [Rust](https://www.rust-lang.org/tools/install) and small number of tools are required.
### NodeJs
Download the \[installer\]\([https://nodejs.org/en/download/](https://nodejs.org/en/download/)\) for your platform and follow the instructions.

Yep, checking once again for modules, the output confirms that the greeting service is available. Writing a small AIR script allows us to use the service:
```text
(xor
(seq
(call relay (service "greeting") [name] result)
(call %init_peer_id% (returnService "run") [result])
)
(call %init_peer_id% (returnService "run") [%last_error%])
)
service GreetingService("service-id"):
greeting: string -> string
func greeting(name:string, node:string, greeting_service_id: string) -> string:
on node:
GreetingService greeting_service_id
res <- GreetingService.greeting(name)
<- res
```
Copy and save the script to greeting.clj and we can use our trusted `fldist` tool:
Compile the script with [`aqua`](https://doc.fluence.dev/aqua-book/getting-started/quick-start) or `aqua-js` and use the resulting file with the`fldist` tool:
