+# Module `webcal`
+
+## Introduction
+
+The module `webcal` is a Java library that facilitates the generation and resolution of iCalendar content for web-based calendar applications. It provides a flexible and easy-to-use API for creating web calendars with customizable settings and events.
+
+### Key features
+
+- Create and manage web calendars with events, including event details such as summary, description, location, and more.
+- Define event classifications and categories for better organization and filtering of calendar data.
+- Set event start and end times, durations, and time zones to handle various scheduling scenarios.
+- Configure event priorities and completion percentages for visual representation in the calendar.
+- Generate iCalendar format output suitable for web calendar applications.
+
+With the `webcal` module, developers can easily integrate calendar functionality into web applications, enabling users to view, add, and manage events in a structured and standardized format. It is designed to simplify calendar-related tasks and enhance the overall user experience when dealing with calendar data on the web.
+
+Please note that the `webcal` module adheres to the iCalendar standard specified in RFC 5545, ensuring compatibility with other calendar applications that support this format.
+
+## Prerequisites
+
+- This whole `JDevKit` is developed by **JDK 17**, which means you have to use JDK 17 for better experience.
+
+## Installation
+
+## Installation
+
+### If you are using `Maven`
+
+It is quite simple to install this module by `Maven`. The only thing you need to do is find your `pom.xml` file in the project, then find the `` node in the `` node, and add the following codes to `` node:
+
+```xml
+
+ ${implementation-builder-group-id}
+ simple-jwt-${any-implementation}
+ ${simple-jwt-${any-implementation}.version}
+
+
+ cn.org.codecrafters
+ simple-jwt-spring-boot-starter
+ ${simple-jwt-spring-boot-starter.version}
+
+```
+
+And run `mvn dependency:get` in your project root folder(i.e., if your `pom.xml` is located at `/path/to/your/project/pom.xml`, then your current work folder should be `/path/to/your/project`), then `Maven` will automatically download the `jar` archive from `Maven Central Repository`. This could be **MUCH EASIER** if you are using IDE(i.e., IntelliJ IDEA), the only thing you need to do is click the refresh button of `Maven`.
+
+If you are restricted using the Internet, and have to make `Maven` offline, you could follow the following steps.
+
+1. Download the `jar` file from any place you can get and transfer the `jar` files to your work computer.
+2. Move the `jar` files to your local `Maven` Repository as the path of `/path/to/maven_local_repo/cn/org/codecrafters/simple-jwt-spring-boot-starter/` and `/path/to/maven_local_repo/${implementation-builder-group-seperated-by-system-seperator}/${implementation_artifact_id}`.
+
+### If you are using `Gradle`
+
+Add this module to your project with `Gradle` is much easier than doing so with `Maven`.
+
+Find `build.gradle` in the needed project, and add the following code to the `dependencies` closure in the build script:
+
+```groovy
+implementation '${implementation-builder-group-id}:simple-jwt-${any-implementation}:${simple-jwt-${any-implementation}.version}'
+implementation 'cn.org.codecrafters:simple-jwt-spring-boot-starter:${simple-jwt-spring-boot-starter.version}'
+```
+
+### If you are not using `Maven` or `Gradle`
+
+1. Download the `jar` file from the Internet.
+2. Create a folder in your project and name it as a name you like(i.e., for me, I prefer `vendor`).
+3. Put the `jar` file to the folder you just created in Step 2.
+4. Add this folder to your project `classpath`.
+
+## Create a web calendar
+
+```java
+var calendar = new WebCalendar()
+ // set the properties for web calendar here.
+ ;
+```
+
+## Add a calendar node to this calendar
+
+```java
+calendar.addNode(new WebCalendarNode()
+ // set properties for this node here.
+ );
+```
+
+## Resolve this calendar.
+
+```java
+var calendarString = calendar.resolve();
+```
