+## FittedCloud
+Another example of the great community shared by the libStorage project, the
+talented people at FittedCloud have provided a driver for their EBS optimizer.
+
+<a class="headerlink hiddenanchor" name="fittedcloud-ebs"></a>
+<a class="headerlink hiddenanchor" name="fittedcloud-ebs-optimizer"></a>
+
+### EBS Optimizer
+The FittedCloud EBS Optimizer driver registers a storage driver named
+`fittedcloud` with the libStorage service registry and provides the ability to
+connect and manage thin-provisioned EBS volumes for EC2 instances.
+
+!!! note
+    This version of the FittedCloud driver only supports configurations where
+    client and server are on the same host.  The libStorage server must be
+    running on each node along side with the FittedCloud Agent.
+
+!!! note
+    This version of the FittedCloud driver does not support co-existing with the
+    ebs driver on the same host. As a result it also doesn't support optimizing
+    existing EBS volumes.	See the [Examples](#fittedcloud-examples) section
+    below for a running example.
+
+!!! note
+    The FittedCloud driver does not yet support snapshots or tags.
+
+#### Requirements
+This driver has the following requirements:
+
+* AWS account
+* VPC - EBS can be accessed within VPC
+* AWS Credentials
+* FittedCloud Agent software
+
+<a class="headerlink hiddenanchor" name="fittedcloud-getting-started"></a>
+
+#### Getting Started
+Before starting, please make sure to register as a user by visiting the
+FittedCloud [customer website](https://customer.fittedcloud.com/register).
+Once an account is activated it will be assigned a user ID, which can be found
+on the Settings page after logging into the web site.
+
+The following commands will download and install the latest FittedCloud Agent
+software. The flags `-o S -m` enable new thin volumes to be created via the
+docker command instead of optimizing existing EBS volumes.
+Please replace the `<User ID>` with a FittedCloud user ID.
+
+```sh
+$ curl -skSL 'https://customer.fittedcloud.com/downloadsoftware?ver=latest' \
+  -o fcagent.run
+$ sudo bash ./fcagent.run -- -o S -m -d <User ID>
+```
+
+Please refer to FittedCloud
+[website](https://customer.fittedcloud.com/download) for more details.
+
+<a class="headerlink hiddenanchor" name="fittedcloud-config"></a>
+
+#### Configuration
+The following is an example with all possible fields configured.  For a running
+example see the `Examples` section.
+
+```yaml
+ebs:
+  accessKey:      XXXXXXXXXX
+  secretKey:      XXXXXXXXXX
+  kmsKeyID:       abcd1234-a123-456a-a12b-a123b4cd56ef
+```
+
+##### Configuration Notes
+- FittedCloud driver shares the ebs driver's configuration
+parameters.
+- The `accessKey` and `secretKey` configuration parameters are optional and
+should be used when explicit AWS credentials configuration needs to be provided.
+FittedCloud driver uses official golang AWS SDK library and supports all other
+ways of providing access credentials, like environment variables or instance
+profile IAM permissions.
+- If the `kmsKeyID` field is specified it will be used as the encryption key for
+all volumes that are created with a truthy encryption request field.
+
+<a class="headerlink hiddenanchor" name="fittedcloud-examples"></a>
+
+#### Examples
+The following example illustrates how to configured the FittedCloud driver:
+
+```yaml
+libstorage:
+  service:    fittedcloud
+ebs:
+  accessKey:  XXXXXXXXXX
+  secretKey:  XXXXXXXXXX
+```
+

+at [this](https://goo.gl/I6mf20) location.
