+## structured logging
+_All usage of this package is the same as `log/slog`_
+
+### install
+```shell
+go get github.com/RealFax/slog@latest
+```
+
+### performance
+you can use build tags to declare which JSON serialization method to use
+
+e.g., use the jsoniter flag to declare the use of `json-iterator/go`
+
+### environment variables
+
+#### LOG_PURE
+type: boolean
+
+This variable declares whether colorful output is disabled.
+
+e.g., LOG_PURE=true
+
+#### LOG_LEVEL
+type: string
+
+- debug
+- info
+- warn
+- error
+
+default: info
+e.g., LOG_LEVEL=debug || LOG_LEVEL=DEBUG
