+Tiny Go webserver that prints OS information and HTTP request to output.
 
 ## Usage
 
 ### Paths
 
-- `/data?size=n[&unit=u]`: creates a response with a size `n`. The unit of measure, if specified, accepts the following values: `KB`, `MB`, `GB`, `TB` (optional, default: bytes).
+#### `/[?wait=d]`
-- `/echo`: webSocket echo.
+
-- `/bench`: always return the same response (`1`).
+Returns the whoami information (request and network information).
-- `/[?wait=d]`: returns the whoami information (request and network information). The optional `wait` query parameter can be provided to tell the server to wait before sending the response. The duration is expected in Go's [`time.Duration`](https://golang.org/pkg/time/#ParseDuration) format (e.g. `/?wait=100ms` to wait 100 milliseconds).
+
-- `/api`: returns the whoami information as JSON.

-- `/health`: heath check

 - `GET`, `HEAD`, ...: returns a response with the status code defined by the `POST`
 - `POST`: changes the status code of the `GET` (`HEAD`, ...) response.
