 # Rubix Server
-Rubix Server is a library for bringing your trained [Rubix ML](https://github.com/RubixML/ML) models into production. Inference servers are stand-alone services that run on your private or public network and wrap your trained estimator in an API that can be queried locally or over the network in real-time using standard protocols. In addition, the library provides async-compatible client implementations for making queries to the server from your PHP applications.

-### Clients
-Clients allow you to communicate directly with a model server using a friendly object-oriented interface inside your PHP applications. Under the hood, clients handle all the networking communication and content negotiation for you so you can write programs *as if* the model was directly accessible in your applications.
-
-Return the predictions from the model:
-```php
-public predict(Dataset $dataset) : array
-```
-
-```php
-use Rubix\Server\RESTClient;
-
-$client = new RESTClient('127.0.0.1', 8080);
-
-// Import a dataset
-
-$predictions = $client->predict($dataset);
-```
-
-Calculate the joint probabilities of each sample in a dataset:
-```php
-public proba(Dataset $dataset) : array
-```
-
-Calculate the anomaly scores of each sample in a dataset:
-```php
-public score(Dataset $dataset) : array
-```
-
-### Async Clients
-Clients that implement the Async Client interface have asynchronous versions of all the standard client methods. All asynchronous methods return a [Promises/A+](https://promisesaplus.com/) object that resolves to the return value of the response. Promises allow you to perform other work while the request is processing or to execute multiple requests in parallel. Calling the `wait()` method on the promise will block until the promise is resolved and return the value.
-
-```php
-public predictAsync(Dataset $dataset) : Promise
-```
-
-```php
-$promise = $client->predictAsync($dataset);
-
-// Do something else
-
-$predictions = $promise->wait();
-```
-
-Return a promise for the probabilities predicted by the model:
-```php
-public probaAsync(Dataset $dataset) : Promise
-```
-
-Return a promise for the anomaly scores predicted by the model:
-```php
-public scoreAsync(Dataset $dataset) : Promise
-```
-
-### REST Client
-The REST Client communicates with the [HTTP Server](#http-server) through the JSON REST API it exposes.
-
-Interfaces: [Client](#clients), [AsyncClient](#async-clients)
-
-#### Parameters
-| # | Param | Default | Type | Description |
-|---|---|---|---|---|
-| 1 | host | '127.0.0.1' | string | The IP address or hostname of the server. |
-| 2 | port | 8000 | int | The network port that the HTTP server is running on. |
-| 3 | secure | false | bool | Should we use an encrypted HTTP channel (HTTPS)? |
-| 4 | middlewares | | array | The stack of client middleware to run on each request/response.  |
-| 5 | timeout | | float | The number of seconds to wait before giving up on the request. |
-| 6 | verify certificate | true | bool | Should we try to verify the server's TLS certificate? |
-
-**Example**
-
-```php
-use Rubix\Server\RESTClient;
-use Rubix\Server\HTTP\Middleware\Client\BasicAuthenticator;
-use Rubix\Server\HTTP\Middleware\Client\CompressRequestBody;
-use Rubix\Server\HTTP\Middleware\Client\BackoffAndRetry;
-use Rubix\Server\HTTP\Encoders\Gzip;
-
-$client = new RESTClient('127.0.0.1', 443, true, [
-	new BasicAuthenticator('user', 'password'),
-	new CompressRequestBody(new Gzip(1)),
-	new BackoffAndRetry(),
-], 0.0, true);
-```
-
-### Client Middleware
-Similarly to Server middleware, client middlewares are functions that hook into the request/response cycle but from the client end. Some of the server middlewares have accompanying client middleware such as [Basic Authenticator](#basic-authenticator) and [Shared Token Authenticator](#shared-token-authenticator).
-
-### Backoff and Retry
-The Backoff and Retry middleware handles Too Many Requests (429) and Service Unavailable (503) responses by retrying the request after waiting for a period of time to avoid overloading the server even further. An acceptable backoff period is gradually achieved by multiplicatively increasing the delay between retries.
-
-#### Parameters
-| # | Param | Default | Type | Description |
-|---|---|---|---|---|
-| 1 | max retries | 3 | int | The maximum number of times to retry the request before giving up. |
-| 2 | initial delay | 0.5 | float | The number of seconds to delay between retries before exponential backoff is applied. |
-
-**Example**
-
-```php
-use Rubix\Server\HTTP\Middleware\Client\BackoffAndRetry;
-
-$middleware = new BackoffAndRetry(5, 0.5);
-```
-
-### Basic Authenticator (Client Side)
-Adds the necessary authorization headers to the request using the Basic scheme.
-
-#### Parameters
-| # | Param | Default | Type | Description |
-|---|---|---|---|---|
-| 1 | username | | string | The user's name. |
-| 2 | password | | string | The user's password. |
-
-**Example**
-
-```php
-use Rubix\Server\HTTP\Middleware\Client\BasicAuthenticator;
-
-$middleware = new BasicAuthenticator('morgan', 'secret');
-```
-
-### Compress Request Body
-Apply the Gzip compression algorithm to the request body.
-
-#### Parameters
-| # | Param | Default | Type | Description |
-|---|---|---|---|---|
-| 1 | level | 1 | int | The compression level between 0 and 9 with 0 meaning no compression. |
-| 2 | threshold | 65535 | int | The minimum size of the request body in bytes in order to be compressed. |
-
-**Example**
-
-```php
-use Rubix\Server\HTTP\Middleware\Client\CompressRequestBody;
-
-$middleware = new CompressRequestBody(5, 65535);
-```
-
-### Shared Token Authenticator (Client Side)
-Adds the necessary authorization headers to the request using the Bearer scheme.
-
-#### Parameters
-| # | Param | Default | Type | Description |
-|---|---|---|---|---|
-| 1 | token | | string | The shared token to authenticate the request. |
-
-**Example**
-
-```php
-use Rubix\Server\HTTP\Middleware\Client\SharedtokenAuthenticator;
-
-$middleware = new SharedTokenAuthenticator('secret');
-```
-
-### Loggers
+## Loggers
 PSR-3 compatible loggers for capturing important server events.
 
-#### File
+### File
 A simple append-only file logger.
