-# Automation Utilities
-
-## 1. Purpose
-Automation Framework that simplifies release process of Docker Images.
-
-## 2. Build
-The application could be built using Gradle Wrapper.
-```
-./gradlew clean build
-```
-
-
-## 3. Execution
-
-```
-./gradlew <option> --args="<parameters>"
-```
-Example:
-```
-./gradlew clean build run --args="validate jetbrains/teamcity-agent:2022.10.2-windowsservercore-2004"
-...
-##teamcity[buildStatisticValue key='SIZE-teamcity-agent:windowsservercore-2004' value='5066342155']
-jetbrains/teamcity-agent:2022.10.2-windowsservercore-2004-windows-10.0.19041.1415-amd64: 
-	 - Original size: 5066342155 (jetbrains/teamcity-agent:2022.10.2-windowsservercore-2004)
-	 - Previous size: 5067986140 (2022.10.1-windowsservercore-2004)
-	 - Percentage change: 0.03% (max allowable - 5.0%)
-```
-
-### 3.1 Available Options
-
-| Action           | Parameter                                                                                                                                  | Description                                                                           |
-|------------------|--------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------|
-| `validate`       | - [`String`] `original Docker image` <br/> - [`String`] `(optional) Dockerhub username` <br/> - [`String`] `(optional) Dockerhub password` | Performs the actions of validating Docker images.                                     |
-| `get-size-trend` | - [`String`] `Docker image`     <br/> - [`String`] `(optional) Dockerhub username` <br/> - [`String`] `(optional) Dockerhub password`      | Print out the trend (CSV) for the size of specified Docker Image using Dockerhub API. |
-
-### 3.2 A note on Dockerhub's authentication
-Dockerhub REST API allows to access private repositories using [JSON Web Token (JWT)](https://docs.docker.com/registry/spec/auth/jwt/).
-Inside of code, the provided credentials - username and persistent access-token - are converted into JWT, which will be used throughout
-the session.
-
-
-### 3.3 TeamCity statistics
-Image size is reported into TeamCity via Service Message using the following pattern: `"SIZE-$currentName"`.
-Please, note that each repository-tag pair might have multiple associated images, whose differences may include:
-* Operating System;
-* Version of Operating System;
-* Architecture;
-Each associated image is being validated within the framework.
-
-### 3.4 A note on automation's dependencies / assumptions
-
-* **Version pattern**. TeamCity Releases following the name pattern: `<year>.<month number>-<platform / OS>`. If previous image
-wasn't explicitly specified, the application would try to determine it automatically. Please, note that automatic determination works
-with minor releases only, e.g. `2022.04.2` -> `2022.04.1`.

-##############################################################################
-#
-#   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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.
