 ## Usage
 
-Install [SAO](https://github.com/egoist/sao) first.
+### Available commands
+
+**Dev**
 
-```bash
-yarn global add sao
-# or
-npm i -g sao
 ```
+# only need run once
+make setup
+
+# start local server
+make dev
+
 
-### From git
+# build binary
+make build
+
+
+# run all unit test
+make test
+
+```
+
+**Migration**
 
 ```bash
-sao dwarvesf/template-go my-project
+# create a new migration
+make migration-new name=example-alter-table
+
+# apply new migrations
+make migrate-up
+
+# rollback a migration version
+make migrate-down
+
+```
+
+### Monitoring
+
+- Get logger instance
+
+```go
+import "github.com/dwarvesf/go-template/pkg/monitoring"
+
+m := monitoring.FromContext(ctx)
+```
+
+- Do logging in handlers and entities package
+
+- Log string format `[package.Function] invokingMethod(param1, param2=%v)`
+
+```go
+// example
+m.Errorf(err, "[entity.LoginUser] GetUserByEmail(ctx, email=%v)", email)
+
+m.Infof("[entity.LoginUser] GetUserByEmail(ctx, email=%v)", email)
+
 ```
 
+### Testing
+
+- Use mockery to generate mock for testing
+- Command: `make mock`
+- Repository testing (DB testing) required an docker DB instance running
+- check example in `repo/user` for db integration testing
+  - sql seed file in testdata
+  - the seed file loaded by testutils
