+# wizard4j
+
+## Introduction
+
+wizard4j: A Java 1.8 library offering a robust collection of utility functions for streamlined development.
+
+## Features
+
+- Comprehensive set of utility functions.
+- Written in Java 1.8.
+- Well-documented code for easy understanding.
+- Regular updates and maintenance.
+
+## Installation
+
+```bash
+git clone --depth 1 https://github.com/sivaosorg/wizard4j.git
+```
+
+## Generation Plugin Java
+
+```bash
+curl https://gradle-initializr.cleverapps.io/starter.zip -d type=groovy-gradle-plugin  -d testFramework=testng -d projectName=wizard4j -o wizard4j.zip
+```
+
+## Modules
+
+Explain how users can interact with the various modules.
+
+### Tidying up
+
+To tidy up the project's Java modules, use the following command:
+
+```bash
+./gradlew clean
+```
+
+or
+
+```bash
+make clean
+```
+
+### Building SDK
+
+```bash
+./gradlew jar
+```
+
+or
+
+```bash
+make jar
+```
+
+### Upgrading version
+
+- file `gradle.properties`
+
+```sh
+ng.name=wizard4j
+ng.version=v1.0.0
+```
+
+## Integration
+
+1. Add dependency into file `build.gradle`
+
+```gradle
+implementation files('libs/wizard4j-v1.0.0.jar') // filename based on ng.name and ng.version
+```
+
+2. Edit file `main Spring Boot application` (optional)
+
+```java
+
+@SpringBootApplication
+@ComponentScan(basePackages = {"org.wizard4j"}) // root name of package wizard4j
+public class ApiApplication {
+    public static void main(String[] args) {
+        SpringApplication.run(ApiApplication.class, args);
+    }
+}
+```

+# Version Releases
+
+## Semantic Versioning (SemVer): `vMAJOR.MINOR.PATCH`
+
+Example:
+
+- v1.0.0
+- v1.0.1
+- v1.1.1
+
+## Pre-release versions: `vMAJOR.MINOR.PATCH-<BETA/RC/SNAPSHOT>.<number>`
+
+Example:
+
+- v1.0.0-beta.1
+- v1.0.0-beta.2
+- v1.2.3-rc1
+- v1.2.3-SNAPSHOT
+
+## Post-release versions: `vMAJOR.MINOR.PATCH-POST.<number>`
+
+Example:
+
+- v1.2.3-post.1
+- v1.2.3-post.2
+
+## Local versions: `vMAJOR.MINOR.PATCH+LOCAL`
+
+Example:
+
+- v1.0.0+local
+- v1.1.0+local
+
+## Caret range versions: `^MAJOR.MINOR.PATCH`
+
+Example:
+
+- ^1.2.3 (similar `>=1.2.3 < 2.0.0`)
+
+## Tilde range versions: `~MAJOR.MINOR.PATCH`
+
+Example:
+
+- ~1.2.3 (similar `>=1.2.3 <1.3.0`)
+
+---
+
+Notes:
+
+- `MAJOR`: major version.
+- `MINOR`: Minor version, often adding new features.
+- `PATCH`: Patch version, typically fixing bugs.
+- `SNAPSHOT`: Indicates a version under development or in progress. It is often used to represent the latest state of the codebase and may include ongoing changes and features that are not yet finalized. This allows developers to work with the most recent developments in a project.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
