def requirements_instructions(prefs_file, prefs):
    return f"""
Requirements:
1. Updated docs to reference the new release version where appropriate.
2. JDK8 and JDK17 compilers and libraries
3. Your Apache ID, already configured with SSH keys on id.apache.org and SSH keys available in this shell session
4. All issues in the target release resolved with valid resolutions (if not, this script will report the problematic JIRAs)
5. A GPG key used for signing the release. This key should have been added to public Apache servers and the KEYS file on the Kafka site
6. Standard toolset installed -- git, gpg, gradle, sftp, etc.
7. ~/.gradle/gradle.properties configured with the signing properties described in the release process wiki, i.e.

      mavenUrl=https://repository.apache.org/service/local/staging/deploy/maven2
      mavenUsername=your-apache-id
      mavenPassword=your-apache-passwd
      signing.keyId=your-gpgkeyId
      signing.password=your-gpg-passphrase
      signing.secretKeyRingFile=/Users/your-id/.gnupg/secring.gpg (if you are using GPG 2.1 and beyond, then this file will no longer exist anymore, and you have to manually create it from the new private key directory with "gpg --export-secret-keys -o ~/.gnupg/secring.gpg")
8. ~/.m2/settings.xml configured for pgp signing and uploading to apache release maven, i.e.,
       <server>
          <id>apache.releases.https</id>
          <username>your-apache-id</username>
          <password>your-apache-passwd</password>
        </server>
        <server>
            <id>your-gpgkeyId</id>
            <passphrase>your-gpg-passphrase</passphrase>
        </server>
        <profile>
            <id>gpg-signing</id>
            <properties>
                <gpg.keyname>your-gpgkeyId</gpg.keyname>
                <gpg.passphraseServerId>your-gpgkeyId</gpg.passphraseServerId>
            </properties>
        </profile>
9. You may also need to update some gnupgp configs:
        ~/.gnupg/gpg-agent.conf
        allow-loopback-pinentry

        ~/.gnupg/gpg.conf
        use-agent
        pinentry-mode loopback

        echo RELOADAGENT | gpg-connect-agent

If any of these are missing, see https://cwiki.apache.org/confluence/display/KAFKA/Release+Process for instructions on setting them up.

Some of these may be used from these previous settings loaded from {prefs_file}:

Do you have all of these setup?"""

---------------------------------------------------------------------------------------------------


Apache Kafka is a distributed streaming platform with four core APIs:


** The Producer API allows an application to publish a stream of records to
one or more Kafka topics.

** The Consumer API allows an application to subscribe to one or more
topics and process the stream of records produced to them.

** The Streams API allows an application to act as a stream processor,
consuming an input stream from one or more topics and producing an
output stream to one or more output topics, effectively transforming the
input streams to output streams.

** The Connector API allows building and running reusable producers or
consumers that connect Kafka topics to existing applications or data
systems. For example, a connector to a relational database might
capture every change to a table.


With these APIs, Kafka can be used for two broad classes of application:

** Building real-time streaming data pipelines that reliably get data
between systems or applications.

** Building real-time streaming applications that transform or react
to the streams of data.


Apache Kafka is in use at large and small companies worldwide, including
Capital One, Goldman Sachs, ING, LinkedIn, Netflix, Pinterest, Rabobank,
Target, The New York Times, Uber, Yelp, and Zalando, among others.

def deploy_instructions():

Next, we need to get the Maven artifacts we published into the staging repository.
Go to https://repository.apache.org/#stagingRepositories and hit 'Close' for the new repository that was created by uploading artifacts.
There will be more than one repository entries created, please close all of them.
In some cases, you may get errors on some repositories while closing them, see KAFKA-15033.
If this is not the first RC, you need to 'Drop' the previous artifacts.
Confirm the correct artifacts are visible at https://repository.apache.org/content/groups/staging/org/apache/kafka/ and build the
jvm and native Docker images following these instructions: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=34840886#ReleaseProcess-CreateJVMApacheKafkaDockerArtifacts(Forversions>=3.7.0)

Ok. We've built and staged everything for the {rc_tag}.

Now you should sanity check it before proceeding. All subsequent steps start making RC data public.

Some suggested steps:

 * Grab the source archive and make sure it compiles: https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka-{release_version}-src.tgz
 * Grab one of the binary distros and run the quickstarts against them: https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka_2.13-{release_version}.tgz
 * Extract and verify one of the site docs jars: https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka_2.13-{release_version}-site-docs.tgz
 * Build a sample against jars in the staging repo: (TODO: Can we get a temporary URL before "closing" the staged artifacts?)
 * Validate GPG signatures on at least one file:
      wget https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka-{release_version}-src.tgz &&
      wget https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka-{release_version}-src.tgz.asc &&
      wget https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka-{release_version}-src.tgz.md5 &&
      wget https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka-{release_version}-src.tgz.sha1 &&
      wget https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/kafka-{release_version}-src.tgz.sha512 &&
      gpg --verify kafka-{release_version}-src.tgz.asc kafka-{release_version}-src.tgz &&
      gpg --print-md md5 kafka-{release_version}-src.tgz | diff - kafka-{release_version}-src.tgz.md5 &&
      gpg --print-md sha1 kafka-{release_version}-src.tgz | diff - kafka-{release_version}-src.tgz.sha1 &&
      gpg --print-md sha512 kafka-{release_version}-src.tgz | diff - kafka-{release_version}-src.tgz.sha512 &&
      rm kafka-{release_version}-src.tgz* &&
      echo "OK" || echo "Failed"
 * Validate the javadocs look ok. They are at https://dist.apache.org/repos/dist/dev/kafka/{rc_tag}/javadoc/
