 ## Example usage
 
+Most basic usage with default settings:
+
 ```go
 import "gitea.larvit.se/pwrpln/go_log"
 
 func main() {
-	log := Log{}
+	log := go_log.Log{}
 	log.SetDefaultValues{}
-	log.Info("My little log message")
+	log.Error("Apocalypse! :O"); // stderr
+	log.Warn("The chaos is near"); // stderr
+	log.Info("All is well, but this message is important"); // stdout
+
+	// Will not be shown due to default log level-limit is "info"
+	log.Verbose("Extra info, likely good in a production environment"); // stdout
+	log.Debug("A lot of detailed logs to debug your application"); // stdout
 }
 ```
+
+Set log level:
+
+```go
+log := go_log.Log{MinLogLvl: go_log.Debug}
+log.SetDefaultValues{}
+
+// Will now show on stdout
+log.Debug("A lot of detailed logs to debug your application");
+// 2022-10-11 07:13:49 [Deb] A lot of detailed logs to debug your application
+```
+
+Using metadata for structured logging:
+
+```go
+log.InfoM("My log msg", []go_log.Metadata{{Name: "foo", Value: "bar"}})
+// 2022-10-11 07:13:49 [Inf] My log msg foo: bar
+```
+
+Setting a logging context to prepend metadata on all log entries:
+
+```go
+log := go_log.Log{}
+log.SetDefaultValues{}
+log.Context = []go_log.Metadata{{Name: "some", Value: "thing"}}
+
+log.Info("A message")
+// 2022-10-11 07:13:49 [Inf] A message some: thing
+
+log.InfoM("Zep", []go_log.Metadata{{Name: "other", Value: "stuff"}})
+// 2022-10-11 07:13:49 [Inf] A message some: thing other: stuff
+```
+
+All available options, and their defaults:
+
+```go
+loc, _ := time.LoadLocation("UTC")
+log := go_log.Log{
+	Context:      []go_log.Metadata{},  // Will be prepended to metadata on all log entries
+	MinLogLvl:    go_log.Info,          // Minimal log level to output
+	Fmt:          go_log.DefaultFmt,    // Log message formatter
+	Stderr:       go_log.DefaultStderr, // Log message outputter for Debug, Verbose and Info
+	Stdout:       go_log.DefaultStdout, // Log message outputter for Warning and Error
+	TimeLocation: loc,                  // Timestamp location/time zone setting
+}
+// Don't run log.SetDefaultValues{} since it will override your settings
+```
