+#   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.

+# Multiplatform library template
+
+## What is it?
+
+It is the barebones library project intended to quickly bootstrap a Kotlin Multiplatform library, that is deployable to Maven Central.
+
+It has only one function: generate the [Fibonacci sequence](https://en.wikipedia.org/wiki/Fibonacci_sequence) starting from platform-provided numbers. Also, it has a test for each platform just to be sure that tests run.
+
+Note that no other actions or tools usually required for the library development are set up, such as [tracking of backwards compatibility]
+(https://kotlinlang.org/docs/jvm-api-guidelines-backward-compatibility.html#tools-designed-to-enforce-backward-compatibility), explicit API mode,
+licensing, contribution guideline, code of conduct and others.
+
+## How do I build it?
+
+1. - [x] Clone this repository ot just [use it as template](https://github.com/Kotlin/multiplatform-library-template/generate)
+1. - [x] Edit library module name and include it in [`settings.gradle.kts`](settings.gradle.kts#L18)
+1. - [x] Edit [`groupId` and `version`](convention-plugins/src/main/kotlin/module.publication.gradle.kts#L10-L11)
+    1. If you need the Android support update namespace [there](library/build.gradle.kts#L38) too
+    1. If you don't need an Android support delete the [`android` section](library/build.gradle.kts#L37-L43)
+1. - [ ] Edit [build targets you need](library/build.gradle.kts#L9-L21)
+
+At this stage, you have everything set to work with Kotlin Multiplatform. The project should be buildable (but you might need to provide actual starting values for the platforms you need).
+
+## How do I make it build on GitHub Actions?
+
+To make it work on GitHub actions, you need to update the [`matrix` section in `gradle.yml`](.github/workflows/gradle.yml#L25-L34). If you didn't change platforms in `build.gradle.kts` you don't need to touch anything. But still read it to understand how it works.
+
+Also, currently, it only runs tests, but you can change this behaviour as you wish by modifying `matrix` and the Gradle [build command](.github/workflows/gradle.yml#L52)
+
+## How do I deploy it to Maven Central?
+
+The most part of the job is already automated for you. However, deployment to Maven Central requires some manual work from your side. 
+
+1. - [ ] Create an account at [Sonatype issue tracker](https://issues.sonatype.org/secure/Signup!default.jspa)
+1. - [ ] [Create an issue](https://issues.sonatype.org/secure/CreateIssue.jspa?issuetype=21&pid=10134) to create new project for you
+1. - [ ] You will have to prove that you own your desired namespace
+1. - [ ] Create a GPG key with `gpg --gen-key`, use the same email address you used to sign up to the Sonatype Jira
+1. - [ ] Find your key id in the output of the previous command looking like `D89FAAEB4CECAFD199A2F5E612C6F735F7A9A519`
+1. - [ ] Upload your key to a keyserver, for example 
+    ```bash
+    gpg --send-keys --keyserver keyserver.ubuntu.com "<your key id>"
+    ```
+1. - [ ] Now you should create secrets available to your GitHub Actions
+    1. via `gh` command
+    ```bash
+    gh secret set OSSRH_GPG_SECRET_KEY -a actions --body "$(gpg --export-secret-key --armor "<your key id>")"
+    gh secret set OSSRH_GPG_SECRET_KEY_ID -a actions --body "<your key id>"
+    gh secret set OSSRH_GPG_SECRET_KEY_PASSWORD -a actions --body "<your key password>"
+    gh secret set OSSRH_PASSWORD -a actions --body "<your sonatype account password>"
+    gh secret set OSSRH_USERNAME -a actions --body "<your sonatype account username>"
+    ```
+    1. Or via the interface in `Settings` → `Secrets and Variables` → `Actions`, same variables as in 1.
+1. - [ ] Edit deployment pom parameters in [`module.publication.gradle.kts`](convention-plugins/src/main/kotlin/module.publication.gradle.kts#L25-L44)
+1. - [ ] Edit deploy targets in [`deploy.yml`](.github/workflows/deploy.yml#L23-L36)
+1. - [ ] Call deployment manually when ready [in Actions](../../actions/workflows/deploy.yml) → `Run Workflow`
+1. - [ ] When you see in your account on https://oss.sonatype.org that everything is fine, you can release your staging repositories and add target `releaseSonatypeStagingRepository` to `deploy.yml` [after this line](.github/workflows/deploy.yml#L60). This way artifacts will be published to central automatically when tests pass.
