description: The Case For Node Native Services

# Add Your Own Node Native Service
As discussed in the [Node](../knowledge_knowledge/node/knowledge_node_services.md) section, some service functionalities useful to a large audience. Such services and can be directly deployed to a peer node as a Wasm module. The remainder of this tutorial guides you through the steps necessary to create and submit a Node Native Service candidate.
If you want to have a service that available out-of-the-box with startup script and scheduled scripts, you can use `builtins deployer` feature. It will upload modules, deploy service, run init script and schedule others.
You should put your service files in the corresponding folder specified in config as `builtins_base_dir`.
In order to have a service available out-of-the-box with the necessary startup and scheduling scripts, we can take advantage of the Fluence [deployer feature](https://github.com/fluencelabs/fluence/tree/master/deploy) for Node native Services. This feature handles the complete deployment process including
### Builtins directory structure
* module uploads,
* service deployment,
* script initialization and scheduling
Note that the deployment process is a fully automated workflow requiring you to merely submit your service assets in the appropriate structure as a PR to the appropriate GitHub repository. At this point you should have a solid grasp of creating service modules and their associated configuration files. See the [Developing Modules And Services](../development_development/) section for details.
Our first step is fork the ??? repo by clicking on the Fork button, upper right of the repo webpage, and follow the instructions to create a local copy. In your local repo copy, checkout a new branch with a new, unique branch name:
```text
git checkout -b MyBranchName
```
In your new branch create a new directory with the service name in the _builtin_ directory:
```text
cd builtins
mkdir my-new-super-service
cd new-super-service
```
Replace my-_new-super-service_ with your service name.
Now we can build and populate the required directory structure with your service assets. You should put your service files in the corresponding my-_new-super-service_ directory specified in config as `builtins_base_dir` **TODO: check if that applies to new repo approach.**
Asset Requirements
In order to deploy a builtin service, you need
* the wasm files for each module as the module build
* the blueprint file for the service
* start and schedule scripts
Just to recap, Blueprints capture module names, blueprint name, and blueprint id. -- builtins
```text
-- builtins
-- {service_alias}
-- scheduled
-- {script_name}_{interval_in_seconds}.air [optional]
