+## How gob works
+`Gob` takes everything defined in the `gob.yaml` as plugin.

+### gob init
+Initialize gob for the project, it will do following initializations 
+1. generate file `gob.yaml`
+2. generate file `.golangci.yaml`, which is the configuration for [golangci-lint](https://github.com/golangci/golangci-lint)
+3. setup `git hooks` if project in the source control.
+   4. commit-msg
+   5. pre-commit
+   6. pre-push
+```shell
+gob init
+```
+`gob.yaml`
+```yaml
+exec:
+    commit-msg-hook: ^#[0-9]+:\s*.{10,}$
+    pre-commit-hook:
+        - lint
+        - test
+    pre-push-hook:
+        - test
+plugins:
+    golangci-lint:
+        alias: lint #When : when issue `gob lint`
+        args: run ./... #What: execute `golangci-lint run ./...`
+        url: github.com/golangci/golangci-lint/cmd/golangci-lint@v1.55.2 #Where: where to download the plugin
+    gotestsum:
+        alias: test
+        args: --format testname -- -coverprofile=target/cover.out ./...
+        url: gotest.tools/gotestsum@v1.11.0
+```
+in most cases you don't need to edit the configuration manually. you can achieve this by [plugin commands](#gob-plugin-install)
