+# Introduction
+
+The Syncbase Allocator service at
+[https://sb-allocator.v.io/](https://sb-allocator.v.io/) (log in with Google
+required) allows you to create and manage up to 3 free cloud Syncbase instances.
+
+Each instance is running in a dedicated container, isolated from all the other
+instances.  Access is restricted to the creator of the instance.
+
+{{# helpers.warning }}
+## Please note
+
+The instances are meant to be used for development.  There are no guarantees
+about availability or performance.  Data stored in the instances can be lost at
+any time.  No sensitive or personal data should be stored in the instances.
+{{/ helpers.warning }}
+
+# Usage
+
+## Viewing your Instances
+
+After logging in, you'll see a list of all your instances (sorted in reverse
+chronological order by creation time).  Each instance displays its address and
+blessing patterns.  You can manage your instances from this view.
+
+## Creating an Instance
+
+The `CREATE NEW` button spins up a new syncbase instance.  It takes about 25
+seconds, after which you'll see your newly created instance.  The instance is
+assigned a stable address that makes reachable from clients and peers.
+
+## Destroying an Instance
+
+The `DESTROY` button removes the instance.  Note, all data in the instance is
+lost; this operation cannot be undone.
+
+## Suspending/Resuming an Instance
+
+The `SUSPEND` button allows you to stop your instance.  `RESUME` restarts it.
+The data in the instance is preserved.
+
+## Resetting an Instance
+
+The `RESET` button re-creates the instance's persisted storage.  Note, all data
+in the instance is lost; this operation cannot be undone.  Resetting preserves
+the instance's address and blessing patterns, which makes it a suitable
+alternative to destroying and recreating an instance when stability of the
+address and blessing patterns is desired.
+
+## Inspecting an Instance
+
+The `DASHBOARD` button opens a page showing load and resource utilization for
+the instance.  The `DEBUG` button opens a page showing details about the
+instance like its blessings, stats, and a browse view of the databases.  See
+[Debugging] for more details.
