+
+## Installation
+
+```shell
+go get github.com/ankorstore/yokai/fxmetrics
+```
+
+## Documentation
+
+### Dependencies
+
+This module is intended to be used alongside:
+
+- the [fxconfig](https://github.com/ankorstore/yokai/tree/main/fxconfig) module
+- the [fxlog](https://github.com/ankorstore/yokai/tree/main/fxlog) module
+
+### Loading
+
+To load the module in your Fx application:
+
+```go
+package main
+
+import (
+	"github.com/ankorstore/yokai/fxconfig"
+	"github.com/ankorstore/yokai/fxlog"
+	"github.com/ankorstore/yokai/fxmetrics"
+	"github.com/prometheus/client_golang/prometheus"
+	"go.uber.org/fx"
+)
+
+func main() {
+	fx.New(
+		fxconfig.FxConfigModule,                        // load the module dependencies
+		fxlog.FxLogModule,
+		fxmetrics.FxMetricsModule,                      // load the module
+		fx.Invoke(func(registry *prometheus.Registry) { // invoke the metrics registry
+			// ...
+		}),
+	).Run()
+}
+```
+
+### Registration
+
+This module provides the possibility to register your metrics [collectors](https://github.com/prometheus/client_golang/blob/main/prometheus/collector.go) in a common `*prometheus.Registry` via `AsMetricsCollector()`:
+
+```go
+package main
+
+import (
+	"github.com/ankorstore/yokai/fxconfig"
+	"github.com/ankorstore/yokai/fxlog"
+	"github.com/ankorstore/yokai/fxmetrics"
+	"github.com/prometheus/client_golang/prometheus"
+	"go.uber.org/fx"
+)
+
+var SomeCounter = prometheus.NewCounter(prometheus.CounterOpts{
+	Name: "some_total",
+	Help: "some help",
+})
+
+func main() {
+	fx.New(
+		fxconfig.FxConfigModule,                       // load the module dependencies
+		fxlog.FxLogModule,
+		fxmetrics.FxMetricsModule,                     // load the module
+		fx.Options(
+			fxmetrics.AsMetricsCollector(SomeCounter), // register the counter
+		),
+		fx.Invoke(func() {
+			SomeCounter.Inc()                          // manipulate the counter
+		}),
+	).Run()
+}
+```
+
+**Important**: even if convenient, it's recommended to **NOT** use the [promauto](https://github.com/prometheus/client_golang/tree/main/prometheus/promauto) way of registering metrics,
+but to use instead `fxmetrics.AsMetricsCollector()`, as `promauto` uses a global registry that leads to data race
+conditions in testing.
+
+Also, if you want to register several collectors at once, you can use `fxmetrics.AsMetricsCollectors()`
+
+### Override
+
+By default, the `*prometheus.Registry` is created by the [DefaultMetricsRegistryFactory](factory.go).
+
+If needed, you can provide your own factory and override the module:
+
+```go
+package main
+
+import (
+	"github.com/ankorstore/yokai/fxconfig"
+	"github.com/ankorstore/yokai/fxlog"
+	"github.com/ankorstore/yokai/fxmetrics"
+	"github.com/prometheus/client_golang/prometheus"
+	"go.uber.org/fx"
+)
+
+type CustomMetricsRegistryFactory struct{}
+
+func NewCustomMetricsRegistryFactory() fxmetrics.MetricsRegistryFactory {
+	return &CustomMetricsRegistryFactory{}
+}
+
+func (f *CustomMetricsRegistryFactory) Create() (*prometheus.Registry, error) {
+	return prometheus.NewPedanticRegistry(), nil
+}
+
+func main() {
+	fx.New(
+		fxconfig.FxConfigModule,                        // load the module dependencies
+		fxlog.FxLogModule,
+		fxmetrics.FxMetricsModule,                      // load the module
+		fx.Decorate(NewCustomMetricsRegistryFactory),   // override the module with a custom factory
+		fx.Invoke(func(registry *prometheus.Registry) { // invoke the custom registry
+			// ...
+		}),
+	).Run()
+}
+```
+
+### Testing
+
+This module provides the possibility to easily test your metrics with the prometheus package [testutil](https://github.com/prometheus/client_golang/tree/main/prometheus/testutil) helpers.
+
+```go
+package main_test
+
+import (
+	"strings"
+	"testing"
+
+	"github.com/ankorstore/yokai/fxconfig"
+	"github.com/ankorstore/yokai/fxlog"
+	"github.com/ankorstore/yokai/fxmetrics"
+	"github.com/prometheus/client_golang/prometheus"
+	"github.com/prometheus/client_golang/prometheus/testutil"
+	"github.com/stretchr/testify/assert"
+	"go.uber.org/fx"
+	"go.uber.org/fx/fxtest"
+)
+
+var SomeCounter = prometheus.NewCounter(prometheus.CounterOpts{
+	Name: "some_total",
+	Help: "some help",
+})
+
+func TestSomeCounter(t *testing.T) {
+	t.Setenv("APP_CONFIG_PATH", "testdata/config")
+
+	var registry *prometheus.Registry
+
+	fxtest.New(
+		t,
+		fx.NopLogger,
+		fxconfig.FxConfigModule,
+		fxlog.FxLogModule,
+		fxmetrics.FxMetricsModule,
+		fx.Options(
+			fxmetrics.AsMetricsCollector(SomeCounter),
+		),
+		fx.Invoke(func() {
+			SomeCounter.Add(9)
+		}),
+		fx.Populate(&registry),
+	).RequireStart().RequireStop()
+
+	// metric assertions
+	expectedHelp := `
+		# HELP some_total some help
+		# TYPE some_total counter
+	`
+	expectedMetric := `
+		some_total 9
+	`
+
+	err := testutil.GatherAndCompare(
+		registry,
+		strings.NewReader(expectedHelp+expectedMetric),
+		"some_total",
+	)
+	assert.NoError(t, err)
+}
+```
