+# A library for tracking statistics and metrics
+
+A simple library for measuring incremental parameters in C++ programs based on the key-value principle.
+
+## Features
+
+- Object oriented
+- Thread safe
+- Easy access to counters using the [] operator
+- Simple incrementing of counters using the ++ operator
+- Initial setup of the list of counters and values
+- List of counter names
+- Retrieving the status of all counters
+- Reset all counters
+- Retrieving the state of all counters and resetting the counters
+## Installation
+
+Just download the latest release and unzip it into your project. You can turn it on with:
+
+```
+#include "metrics/lib/metrics.hpp"
+using namespace marcelb;
+```
+
+## Usage
+
+```c++
+// init
+Metrics stats;
+// operator [] and increment ++
+stats["access"]++;
+// print couter access
+cout << stats["access"];
+// get counters names
+auto listCounterNames = stats.keys();
+// get all couters
+auto data = stats.get_data();
+// reset counters
+stats.clear();
+// set counters
+map<string, uint> MyStats = {{"access", 3},{ "error", 0}};
+stats.set(MyStats);
+// get and clear all counters
+auto dataWithClear = stats.get_data_and_clear();
+```
