 # commitlint-wizardoc
-Constraint rules that apply to the commit message for Wizardoc projects.
+commitlint-wizardoc is a configuration package for [commitlint](https://github.com/conventional-changelog/commitlint) that contain some rules and plugins to check that your commit message conform to the `Wizardoc` convention.
+
+## Usage
+If you have never used commitlint before, you can visit [commitlint document](https://commitlint.js.org/) for more detail.
+
+### Install
+You can install `commitlint-wizardoc` using NPM and YARN as well.
+
+```shell
+# NPM
+npm i commitlint-wizardoc -D
+
+# YARN
+yarn add commitlint-wizardoc -D
+```
+
+### Configuration
+Create a [commitlint](https://github.com/conventional-changelog/commitlint) config in the root path of your project, and you can extends the `wizardoc` config to do all configuration work.
+
+For instance, create `.commitlintrc.js` that looks like:
+
+```js
+module.exports = {
+  // This line config will read the NPM package named "commitlint-config-wizardoc", so please make sure you have installed it before config this line.
+  extends: 'wizardoc'
+}
+```
+
+Now, that's all you need to do.
+
+## Convention
+The commit message should consists of four parts:
+```
+![Feat::scope] some sentence
+^  ^      ^          ^
+|  |      |          |
+|  |      |          |
+|  |      |          |- Subject(required)
+|  |      |
+|  |      |- Scope(optional)
+|  |
+|  |- Type(required)
+|
+|- Break change symbol(optional)
+```
+
+- `Break change symbol`: it can indicate that the commit contains break change
+- `Type`: commit type that can only be one of the following types
+  - Feat
+  - Init
+  - Remove
+  - Delete
+  - Update
+  - Refactor
+  - Move
+  - New
+  - Add
+  - Patch
+  - Fix
+  - Test
+  - Stub
+  - Chore
+- `Scope`: scope of modification
+- `Subject`: description of the commit 
+
+## Override configs
+You can also override `Wizardoc` config to create your own configuration as well.
+
+```js
+module.exports = {
+  extends: 'wizardoc',
+  rules: [
+    // Set the $ as the third parameter if you wanna change break symbol to $
+    "break-change-prefix": [2, "always", '$'],
+  ]
+}
+```
