## Installation
You can install this library from Quicklisp, but you want to receive updates quickly, then install it from Ultralisp.org:
“‘
(ql-dist:install-dist "http://dist.ultralisp.org/"
:prompt nil)
(ql:quickload :reblocks-prometheus)
“‘
<a id="x-28REBLOCKS-PROMETHEUS-DOCS-2FINDEX-3A-3A-40USAGE-2040ANTS-DOC-2FLOCATIVES-3ASECTION-29"></a>
## Usage
Inherit your Reblocks application from [‘prometheus-app-mixin‘][db0d] class:
“‘
(defapp app
:subclasses (reblocks-prometheus:prometheus-app-mixin)
:prefix "/")
“‘
A new route ‘/metrics‘ will be added to serve metrics in Prometheus format.
