+# micro-analytics-adapter-memory
+
+This is an in-memory adapter for [micro-analytics][].
+
+#### Why would you want to to use an in memory adapter for micro-analytics?
+
+It can be useful for testing and when deploying test deployments to now.sh.
+now does not support writing to the filesystem, which makes micro-analytics
+unable to start with the flat-file-db-adapter. In production use, you would
+probably want to  use a real database if you care about the data collected.
+
+## Usage
+
+```
+npm install micro-analytics-cli micro-analytics-adapter-memory
+micro-analytics --adapter memory
+```
+
+and open [localhost:3000](https://localhost:3000).
