+  Provides a DigitalOcean Floating IP resource.
+---
+
+# digitalocean\_floating_ip
+
+Provides a DigitalOcean Floating IP to represent a publicly-accessible static IP addresses that can be mapped to one of your Droplets.
+
+## Example Usage
+
+```
+resource "digitalocean_droplet" "foobar" {
+    name = "baz"
+    size = "1gb"
+    image = "centos-5-8-x32"
+    region = "sgp1"
+    ipv6 = true
+    private_networking = true
+}
+
+resource "digitalocean_floating_ip" "foobar" {
+    droplet_id = "${digitalocean_droplet.foobar.id}"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional) The region that the Floating IP is reserved to. 
+* `droplet_id` - (Optional) The ID of Droplet that the Floating IP will be assigned to.
+
+~> **NOTE:** A Floating IP can be assigned to a region OR a droplet_id. If both region AND droplet_id are specified, then the Floating IP will be assigned to the droplet and use that region
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `ip_address` - The IP Address of the resource
