### Creating new nodes
The plugin nature of Node-RED means anyone can create a new node to extend
its capabilities. Eventually, the nodes will be npm-installable, but we're not
there yet.
its capabilities.
We want to avoid duplication as that can lead to confusion. Many of our existing
nodes offer a starting point of functionality. If they are missing features,
we would rather extend them than add separate 'advanced' versions. But the key
to that approach is getting the UX right to not lose the simplicity.
We are also going to be quite selective over what nodes are included in the main
repository - enough to be useful, but not so many that new user is overwhelmed.
To contribute a new node, please raise a pull-request against the
`node-red-nodes` repository.
Eventually, the nodes will be npm-installable, but we're not there yet. We'll
also have some sort of registry of nodes to help with discoverability.
