+# @cisl/zepto-logger
+
+A minimalistic, zero-dependency logger that writes messages to the console with
+the current timestamp. Good for debugging, but for a production grade
+application, probably worth looking elsewhere.
+
+## Installation
+
+```bash
+npm install @cisl/zepto-logger
+```
+
+## Usage
+
+```javascript
+const {setLogLevel, logExpression} = require('@cisl/zepto-logger');
+
+// by default the logLevel starts at 1
+logExpression('This message will print', 1);
+logExpression('This message will not print', 2);
+
+setLogLevel(2);
+logExpression('This message will now print', 2);
+
+// can also log objects and other types, not just strings
+logExpression({foo: 1, bar: 2, baz: {a: 1, b: 2}}, 1);
+```
