 While much of the syntax between the two is the same, there are many conventions supported by Asciidoctor that did not exist in AsciiDoc. While the Asciidoctor project has tried to provide back-compatibility with the older project, that may not be true forever. For this reason, it's strongly recommended to only use the Asciidoctor User Manual as a reference for any syntax that's not described here.

-
-The main published artifact of the Solr Reference Guide is a PDF document.
-
-The PDF version of the Ref Guide uses `asciidoctor-pdf` (indirectly) to convert the `.adoc` files to PDF.
-
-In order for all of the various files to be converted into a single, large, PDF file, another `.adoc` file must be created.
-
-== About asciidoctor-pdf
-
-Our PDF build process uses the https://github.com/asciidoctor/asciidoctor-ant[`asciidoctor-ant`] project to integrate Asciidoctor.
-
-The `asciidoctor-ant` project is really an Ant wrapper around https://github.com/asciidoctor/asciidoctorj[`asciidoctorj`]. This is a Java binding of several Asciidoctor projects that produces a .jar that includes Asciidoctor, Asciidoctor PDF and Asciidoctor EPub.
-
-Since it is a binding for the Ruby implementations of these three projects, they each work the same way they would if we were using the Ruby versions.
-
-== Configuring the PDF Theme
-
-Nearly all of the styling and layout of the PDF is controlled by a single YAML file that is called a theme.
-
-See the section <<Modifying the Theme>> for information on how to update the theme.
-
-=== Declaring the Theme to Use
-
-Our theme is `refguide-theme.yml`, found in `solr/solr-ref-guide/pdf/themes`.
-
-New themes must be named to include `-theme.yml` at the end. They must also be in proper YAML format.
-
-The theme to use when generating the PDF is defined with the `pdf-style` attribute. Only the first part of the file name is used. So, a theme file named `refguide-theme.yml` is selected by defining `pdf-style=refguide`.
-
-In the section <<Asciidoctor PDF Attributes>> below, we can see how we've declared this in our Ant target.
-
-=== Modifying the Theme
-
-All of the styling capabilities are described in the https://github.com/asciidoctor/asciidoctor-pdf/blob/master/docs/theming-guide.adoc[Asciidoctor PDF Theming Guide].
-
-== About the Uber-Document
-
-In order for all of the files in `.adoc` format to be compiled into a single PDF, we need to give the process one `.adoc` file (an "uber-document") that includes all of the content we want in the PDF. In other words, there is no command that says "take all the files in this directory and make one PDF".
-
-Asciidoctor has a nice feature called the _include directive_, which allows you to insert content from another file into the current file (more details in the http://asciidoctor.org/docs/user-manual/#include-directive[Asciidoctor documentation]).
-
-We wanted to make sure we didn't add to the burden of maintaining the PDF by asking everyone to update the uber-document or trying to institute some sort of check on if all the pages are included and in the right place in the hierarchy. Instead, the uber-document is build programmatically at build time.
-
-The uber-document is found in `solr/solr-ref-guide/src/pdf/SolrRefGuide-all.adoc`. This document is very simple - it includes only the Apache license statement and a single `include` directive to another file:
-
-[source]
-\include::_data/pdf-main-body.adoc[]
-
-The Ant target `build-pdf` includes a dependency on another target, `build-nav-data-files`. This target looks at each document and builds the `pdf-main-body.adoc` file with the proper hierarchy of all pages.
-
-NOTE: You will not see the `pdf-main-body.adoc` in `solr/solr-ref-guide/src/_data` directory. This file exists only once it has been built, and it is placed in the build directory, at `solr/solr-ref-guide/build/content_data`.
-
-== Configuring the build-pdf Ant Target
-
-Since most of the styling and layout is defined by the theme, the options that must be configured in the Ant target relate to where to find referenced files, font directories, image directories, and similar top-level document settings.
-
-There are two types of settings at work in our Ant target. First are the settings which are part of the `asciidoctor-ant` jar. Second, we are able to declare any Asciidoctor PDF attribute (setting) that we want to apply to the entire PDF.
-
-Our Ant target (`build-pdf`) uses the following settings:

-</asciidoctor:convert>
-----
-
-There are a lot of options here. Note that some include the `<attribute>` tag and some do not. Those that do not are options provided by `asciidoctor-ant` so don't need any special syntax. The options with the `<attribute>` tag are not provided by `asciidoctor-ant` but are supported by `asciidoctor-pdf` so will be applied when the target is run. A few of these are custom variables that we have defined ourselves.
-
-=== Asciidoctor Ant Attributes
-
-`sourceDirectory="${build.content.dir}/pdf"`:: Defines where to find the source file to build the PDF. The variable is declared earlier in `build.xml`.
-`sourceDocumentName="SolrRefGuide-all.adoc"`:: The source file name, which in our case will be built as described in the section <<About the Uber-Document>>.
-`baseDir="${build.content.dir}"`:: The root path for any included files.
-`outputDirectory="${build.dir}"`:: Defines where the resulting PDF file should go. In this case, the
-`backend="pdf"`:: The output format. The `asciidoctor-ant` jar is also capable of outputting DocBook format, so we must declare we want a PDF.
-`extensions="adoc"`:: The file extensions to allow for the source document.
-`sourceHighlighter="coderay"`:: The library to use for syntax highlighting source code.
-`imagesDir="${build.content.dir}"`:: The directory to use to find images referenced in the documents.
-`doctype="book"`:: Adds support for book-style format and sections, such as a preface, colophon, glossary, index, etc.
-`safemode="unsafe">`:: Allows including resources that are external to the parent directory of the source file. For example, source examples could be pulled from Solr's source code instead of copied to documentation. This setting allows that to happen.
-
-=== Asciidoctor PDF Attributes
-
-`<attribute key="icons" value="font" />`:: The style of icons.
-`<attribute key="icon-set" value="fa" />`:: The icon set to use. We use the Font Awesome font set.
-`<attribute key="pdf-stylesDir" value="./pdf/themes"/>`:: The directory to find PDF themes. See the section <<Configuring the PDF Theme>> for more details on themes.
-`<attribute key="pdf-style" value="refguide"/>`:: The theme to use. The theme must be saved in the directory referenced with the `pdf-stylesDir` attribute, and must be named `<pdf-style>-theme.yml`.
-`<attribute key="pdf-fontsDir" value="./pdf/fonts"/>`:: The directory where to find fonts declared in the theme.
-`<attribute key="figure-caption!" value='' />`:: Sets caption labels and numbers (such as "Figure 1") to block images. The exclamation at the end of this setting in our config _disables_ figure captioning.
-`<attribute key="idprefix" value='' />`:: Sets the prefix for auto-generated section IDs, such as those from headings in a page. In our config, this is effectively "null", so auto-generated section IDs do not have any prefix.
-`<attribute key="idseparator" value='-' />`:: Sets the separator between words in auto-generated section IDs to a hyphen (`-`).
-
-=== Custom Attributes
-
-These attributes use variables that are inserted by Ant during the PDF creation process. This allows us to pull from standard Lucene/Solr build files, and not have to update several places for any release. The Ant build process updates the `_config.yml` file from the `_config.yml.template`, then these attributes pull the proper value from that file.
-
-`<attribute key="solr-guide-draft-status" value="${solr-guide-draft-status}" />`:: Indicates if this is a `DRAFT` PDF or not.
-`<attribute key="solr-guide-version" value="${solr-guide-version}" />`:: The version of the Guide itself.
-`<attribute key="solr-docs-version" value="${solr-docs-version}" />`:: The version of Solr covered by this guide.
-`<attribute key="solr-javadocs" value="${solr-javadocs}" />`:: Sets the path for Solr javadoc links to include the right path for the current release version.
-`<attribute key="lucene-javadocs" value="${lucene-javadocs}" />`:: Sets the path for Lucene javadoc links to the right path for the current release version.
-`<attribute key="build-date" value="$\{DSTAMP}" />`:: Sets the date of the build to add the date to the footer of each page of the PDF.
-`<attribute key="build-year" value="${current.year}" />`:: Sets the year of the build to add the date to the copyright notice.

+. Build and publish the DRAFT version.
+. Continue to update docs as needed while Lucene/Solr artifact VOTE thread is ongoing.
+. After VOTE has passed, build and publish final version to overwrite DRAFT watermarked pages.
 
 == Pre-Requisites
 
-The PDF version of the Solr Reference Guide is the *official* version. As such, it is voted on by the community before release, and is treated as an official artifact of the Lucene/Solr project.
+In order to build the Ref Guide, you must have the following:
 
-=== Pre-Requisites for PDF
+* You have checked out the Lucene/Solr source code on the machine you will be doing the release from.
+* You have Subversion installed. This is needed for committing the HTML files to the production website repo.
+* You have installed Ruby and several gems described in the README file located at `solr/solr-ref-guide/README.adoc` in your Lucene/Solr checkout.
+* All builds must be done from the release branch the Guide is for.
 
-The build process downloads the required .jar to build the PDF version, so the only pre-requisites are for the publication process:
+NOTE: Builds are available via https://builds.apache.org/view/L/view/Lucene/[Jenkins] for several branches. However, these HTML pages will have the `DRAFT` status noted in them and are not suitable for final production publishing.
 
-* You have checked out the Lucene/Solr source code on the machine you will be doing the release from. You will need scripts in the `dev-tools` directory.
-* You have generated a GPG key. See the Apache documentation on https://www.apache.org/dev/release-signing.html#generate[generating a code signing key].
-* You have Python 3 installed. This is needed to poll the mirrors after release to be sure it's propagated enough to make the announcement.
-* You have Subversion installed. This is needed for committing the PDF to `dist/dev` and `dist/releases` repos.
+== Build the DRAFT Guide
 
-=== Additional Pre-Requisites for HTML
+The build process generates the page hierarchy and builds the HTML pages with custom templates the Lucene/Solr project has defined.
 
-To build the PDF locally, you need several required dependencies, listed in `solr-ref-guide/README.adoc`. If you do not have these dependencies locally, you cannot build and publish the Ref Guide.
+To build the HTML:
 
-NOTE: Builds are available via Jenkins for several branches. However, these HTML pages will have the `DRAFT` status noted in them and will not be suitable for publishing.
-
-== Generate the PDF & HTML
-
-No local dependencies are required to build the PDF. The Ant target will download the jars and other items it requires.
-
-The build process generates the PDF, including the page hierarchy, and then runs an optimization script on the PDF to make it smaller.
-
-To build the PDF:
-
-. Run `ant clean default -Dsolr-guide-version=X.Y`, where `X.Y` is the version you want to publish (i.e., `7.4`).
-. The resulting PDF will be in `solr/build/solr-ref-guide`. The HTML files will be in `solr/build/solr-ref-guide/html-site`.
-
-IMPORTANT: The `-Dsolr-guide-version` system property is optional. By default the build system uses the `version.properties` of the current branch and assumes this is a `DRAFT` build. Including this system property ensures the DRAFT watermark and labels are removed from the HTML files.
-
-== Prepare & Upload Release Candidate
-
-=== Upload PDF to dist/dev 
-
-The `dist/dev` Subversion repository includes a directory for the Solr Ref Guide at https://dist.apache.org/repos/dist/dev/lucene/solr/ref-guide/[`lucene/solr/ref-guide`] which can host the release candidate (RC) during the VOTE stage of the process.
-
-These steps walk through checking out this directory and uploading the Guide to it.
-
-. Checkout the directory: `svn co https://dist.apache.org/repos/dist/dev/lucene/solr/ref-guide solr-ref-guide-rc`
-* If you have already checked out this directory, you can simply update it: `svn update solr-ref-guide-rc`
-. Change directories so `solr-ref-guide-rc` is your working directory (`cd solr-ref-guide-rc`).
-
-IMPORTANT: The next step requires that you have already generated your GPG keys. Your GPG passphrase will be required.
-
-[start=3]
-. Run the Prep Ref Guide script to prepare the RC. This script ensures proper naming of the PDF file, generates 
- `.sha512` and `.asc` files and creates the proper RC sub-directories under `solr-ref-guide-rc`.
-.. The structure of the input is: `prep-solr-ref-guide-rc.sh <path/PDFfilename> <Solrversion-RC#> GPGkey`.
-.. From the `solr-ref-guide-rc` directory, it will look something like this:
+. Navigate to `./solr/solr-ref-guide`, where the Guide's `build.xml` is located.
+. Run:

-==== Step 3: Push Staging extpaths.txt to Production
+*Step 3: Push Staging extpaths.txt to Production*
 
 The `extpaths.txt` works by listing paths that should be ignored when the CMS syncs the staging and production repositories. Publishing staging to production will only succeed if the paths listed in `extpaths.txt` exist in production. At the same time, if a path exists in production but not in staging it will be deleted unless it is defined in `extpaths.txt`.

-== Hold a VOTE
-Votes must be sent to the lucene-dev mailing list (`dev@lucene.apache.org`).
-
-. Send an email to `dev@lucene.apache.org` with subject, "VOTE: Release Apache Solr Ref Guide for Solr X.Y".
-. The body of the email should include the full URL of the RC directory in the `dist/dev` repo. Such as: https://dist.apache.org/repos/dist/dev/lucene/solr/ref-guide/apache-solr-ref-guide-7.0-RC0
-. You can add your own +1 to the vote announcement email.
-. If there are issues that need to be resolved, you can start the process over, using RC1, RC2, etc., as needed.
-
-NOTE: Ideally, the HTML version will also be available for voters to review.
-
 == Publish the Guide
 
-=== Move the PDF to dist/releases
+There are two steps to publishing the Guide: first, uploading the DRAFT pages with the production-ready version; and second, updating links to point to the new Guide.
 
-Once at least three PMC members have voted for release (see https://www.apache.org/foundation/voting.html#ReleaseVotes[Apache Voting Process] for details on the rules for votes), the release candidate can be released.
+=== Update DRAFT for Release
 
-. Use the Publish Solr Ref Guide script (`publish-solr-ref-guide.sh`) to generate the proper SVN commands to be run to execute a remote move of the RC files to the final `dist/releases` repository.
-.. The script takes only the version and _RC number that passed the vote_ as inputs, such as `7.0-RC0`.
-.. The input and output of the script will look like this:
+Since the Guide has already been published, you need to update the production
+website repository and overwrite the existing files:
+
+*Build Production Guide*
+
+Build the Guide locally with a parameter for the Guide version. This requires the same <<Pre-Requisites,pre-requisites>> from above.
+
+[source,bash]
+$ant clean default -Dsolr-guide-version=X.Y
+
+where `X.Y` is the version you want to publish (i.e., `7.7`).
+
+IMPORTANT: The `-Dsolr-guide-version` system property is optional if you build drafts locally or as pre-publication DRAFTs (i.e., not for publication). By default the build system uses the `lucene/version.properties` file in the current branch and assumes this is a `DRAFT` build which will have a DRAFT watermark and other labels on the pages. Including the `-Dsolr-guide-version` system property ensures the DRAFT watermark and labels are removed from the HTML files.
+
+*Pull Production Repo and Upload New Files*
+
+. Checkout the directory you need to update from the production repo:

-. The release should propagate to as many mirrors as possible before announcing the release, generally 24 hours is long enough. Use the Poll Mirrors script (`poll-mirrors.py`) to check the status:
+$ svn co https://svn.apache.org/repos/infra/websites/production/lucene/content/solr/guide/<dir>
 +
-[source,bash]
-python3 -u ~/lucene-source/dev-tools/scripts/poll-mirrors.py -details -p lucene/solr/ref-guide/apache-solr-ref-guide-X.Y.pdf
+* This command checks out the Guide version directory into a local subdirectory with the same name as the version (such as "7_7"). You can provide a better name locally if you prefer by adding it to the end of the command shown above.
+* Don't shortcut this and download the whole production website. It will take an incredibly long time and that will feel like _forever_.
+. Copy the files from the build location to the checked out Guide directory. For example, if we needed to replace the Guide for Solr 7.7, we'd do `cp -r ./solr/build/solr-ref-guide/html-site 7_7/.`
+. Use `svn status` to see the files modified. If there are any pages added or deleted, use `svn add <file>` or `svn rm <file>` as needed.
+. Commit the changes: `svn commit -m "Update production 7.7 Ref Guide"`
 
-* This script requires Python 3 to be installed on your machine.
-* If you have over 85% of the mirrors with the file, it's OK to go ahead with the announcement.
-. You may get an automated email about updating the ASF release repository; you can safely ignore this email.
+*Verify Upload Successful*
 
-=== Archive Old PDF Versions
-. The `dist/releases` repo is only meant to keep the latest releases. Shortly after new releases are mirrored, they are copied to `archive.apache.org`, so older releases can safely be deleted from `dist/releases` since they have been backed up in the archives.
-.. Run the Archive Ref Guide script (`archive-solr-ref-guide.sh`) using the X.Y version of the Ref Guide that has just been published. Older RCs will also be removed.
-.. Again, this script doesn't do any direct removal of files, it only outputs SVN commands for you to copy and paste:

-The Lucene PMC is pleased to announce that the Solr Reference Guide
-for 7.0 is now available.
-
-This 1,035-page PDF is the definitive guide to using Apache Solr, the
-search server built on Lucene.
-
-The PDF Guide can be downloaded from:
-https://www.apache.org/dyn/closer.cgi/lucene/solr/ref-guide/apache-solr-ref-guide-7.0.pdf.
-
-It is also available online at https://lucene.apache.org/solr/guide/7_0.
-----
-
-If the Guide is being published more than a day or two after the application itself, you should update the Solr website news page with the announcement (https://lucene.apache.org/solr/news.html).
-
-== Updating HTML Files after Publication
-
-If you need to re-publish an existing online copy of the Guide, you will need to checkout the directory in production website repository and overwrite the existing files:
-
-. Build the new HTML files locally (`ant clean build-site`), or download them from Jenkins.
-. Checkout the directory you need to update from the production repo: `svn co https://svn.apache.org/repos/infra/websites/production/lucene/content/solr/guide/<dir>`.
-* This command checks out the Guide version directory into a local subdirectory with the same name as the version (such as "6_5"). You can provide a better name locally if you prefer by adding it to the end of the command shown above.
-* Don't shortcut this and download the whole production website. It will take an incredibly long time and that will feel like _forever_.
-. Copy the files from the build location to the checked out Guide directory. For example, if we needed to replace the current Guide for Solr 6.5, we'd do `cp -r <checkoutroot>/solr/build/html-site 6_5/.`
-. Use `svn status` to see the files modified.
-. If there are any pages added or deleted, use `svn add <file>` or `svn rm <file>` as needed.
-. Commit the changes: `svn commit -m "Update production 6.5 Ref Guide"`
+In the above example, you would change the `7_7` part of the path to the right version (`8_0`, etc.).
