+# Pulumi DigitalOcean Droplets
+
+Starting point for building a Pulumi sample architecture on DigitalOcean.
+
+## Running the App
+
+1. Create a new stack:
+
+ ```
+ $ pulumi stack init digitalocean-ts-loadbalanced-droplets
+ ```
+
+1. Configure the project:
+
+ ```
+ $ pulumi config set --secret digitalocean:token YOURDIGITALOCEANTOKEN
+ ```
+
+1. Restore NPM dependencies:
+
+ ```
+ $ npm install
+ ```
+
+1. Run `pulumi up` to preview and deploy changes:
+
+ ``` 
+ $ pulumi up
+ Previewing update (digitalocean-ts-loadbalanced-droplets):
+ ...
+
+Updating (digitalocean-ts-loadbalanced-droplets):
