 Oracle Cloud Free Tier offer includes Always Free resources, such as 2 VMs with 1 CPU and 1 GB RAM each or Ampere ARM based VMs equivalent to 4 CPU and 24 GB RAM per month, which is sufficient to run a Unifi Controller for a small installation with no charge and no expiration date

 Oracle uses "stacks" that automates the provisioning of an environment using Terraform.  Using only a single zip file, a Unifi Controller can be provisioned quickly with very little interaction.
 
+## Breaking Changes
+
+* The project name now only allows alphanumeric characters and no longer supports - or _.  This is due to enabling DNS on the VCN to allow for static IP assignment

 ## Configuration
 
 1) Download the .zip file.
 2) Register an account on Oracle Cloud.

-    * Recommended: Go to Menu>Compute>Instances>Create Instance. Click on "Edit" on the Placement panel and take note of the Availability domain number that is tagged with "Always Free Eligible". The process can then be cancelled. This number will be used later. (At this time, Ampere A1 can be created in any Availability Domain) ![Availability Domains](./images/availability-domain.jpg)

 3) Navigate to Menu>Storage>Object Storage & Archive>Buckets>Create Bucket. Give the bucket a name, such as "unifibackup". This will be used to store backup files outside of the VM Instance. Optional: Take note of the "Namespace: " value after creating the bucket as it will be used if mounting the bucket for autobackups.

-    * If the process encounters an error stating "shape VM.Standard.E2.1.Micro not found", verify the Availability Domain that is Always Free Eligible for your region, or try a different number 1-3.
-    * If the process encounters an error stating "Out of host capacity", your Region does not currently have available resources for Always Free instances. In the Oracle Forums regarding this error, they recommend trying again later as capacity is always being added.

You can also upgrade to "Pay As You Go" (PAYG) which makes the Ampere instances much more available, and as long as you stay under the Free Tier limits, continues to be free.
