+= How to Contribute to the Reference Manual
+
+The Spring Framework reference manual uses http://asciidoctor.org/[asciidoctor]. This
+document describes how to contribute documentation updates.
+
+== Building with Gradle
+
+You can build the documentation using Gradle using the `asciidoctor` task. For example,
+from the project root execute the following command:
+
+[indent=0]
+----
+	./gradlew asciidoctor
+----
+
+The generated reference manual will then be available at
+`build/asciidoc/html5/index.html`.
+
+== Live Editing
+
+One of the nice features about using Asciidoctor is the support for live editing.
+
+You will find a Guardfile already present at
+`spring-framework/src/docs/asciidoc/Guardfile`. First, follow the setup instructions
+within the
+http://asciidoctor.org/docs/editing-asciidoc-with-live-preview/[Editing AsciiDoc
+with Live Preview] document. Once you have done that, there are additional gems to
+install to make it work (assuming that you are using http://livereload.com/[LiveReload]):
+
+[indent=0]
+----
+	gem install guard-rspec guard-livereload
+----
+
+When running `guard start` within the `src/asciidoc/` folder, any changes to the
+`src/asciidoc/index.adoc` file are automatically written to
+`src/asciidoc/build/index.html`.
+
+== Troubleshooting
+
+* If you are using LiveReload, select _Allow access to file URLs_ in the
+LiveEdit plugin options of your browser.
+* The icon used to enable _LiveReload_ can be a bit confusing. The dot is empty when it
+is disabled and full when the plugin is active. Make sure to enable it on the tab
+displaying the `index.html` file.
+* Ensure you are _not_ running `guard start` at all, as two instances could not run at
+the same time. To exit a current session in a clean way, type `e` in the shell.
+
+== Documentation Notes
+
+Some notes on the documentation.
+
+* Documentation is wrapped at 90 chars. Ensure that you manually wrap your edits.
+* Tabs are used for indentation. Do not use spaces.
+* Follow the existing style when inserting `source` blocks.
+
+Here are some useful resources for working with Asciidoctor:
+* http://asciidoctor.org/docs/asciidoc-syntax-quick-reference/[Asciidoctor Quick Reference]
+* http://asciidoctor.org/docs/user-manual/[Asciidoctor Manual]

+## Take Your First Steps

-### Code of Conduct
+### Understand the basics

-This project is governed by the [Spring Code of Conduct](CODE_OF_CONDUCT.adoc).
-By participating you are expected to uphold this code.
-Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
+Not sure what a pull request is, or how to submit one? Take a look at GitHub's
+excellent [help documentation][] first.

-### How to Contribute
+### Search Stack Overflow first; discuss if necessary

-#### Discuss
+If you're unsure why something isn't working or wondering if there is a better
+way of doing it please check on Stack Overflow first and if necessary start
+a discussion. This is the official list of
+[Spring project tags](https://spring.io/questions). In short the issue tracker
+should be used to report issues and make feature requests.

-If you have a question, check StackOverflow using
-[this list of tags](https://spring.io/questions), organized by Spring project.
-Find an existing discussion or start a new one if necessary.
+### Search JIRA; create an issue if necessary

-If you suspect an issue, perform a search in the
-[JIRA issue tracker](https://jira.spring.io/browse/SPR), using a few different keywords.
-When you find related issues and discussions, prior or current, it helps you to learn and
-it helps us to make a decision.
+Is there already an issue that addresses your concern? Do a bit of searching
+in our [JIRA issue tracker][] to see if you can find something similar. If you
+do not find something similar, please create a new JIRA issue before submitting
+a pull request unless the change is truly trivial -- for example: typo fixes,
+removing compiler warnings, etc.

-#### Create a Ticket
+### Sign the Contributor License Agreement (CLA)

-Reporting an issue or making a feature request is a great way to contribute. Your feedback
-and the conversations that result from it provide a continuous flow of ideas. 
+If you have not previously done so, please sign the [Contributor License Agreement][].
+If you forget to do so, you'll be reminded when you submit a pull request.

-Before you create a ticket, please take the time to [research first](#discuss).
+## Create a Branch

-If creating a ticket after a discussion on StackOverflow, please provide a self-sufficient description in the ticket, independent of the details on StackOverview. We understand this is extra work but the issue tracker is an important place of record for design discussions and decisions that can often be referenced long after the fix version, for example to revisit decisions, to understand the origin of a feature, and so on.
+### Branch from `master`

-When ready create a ticket in the [JIRA issue tracker](https://jira.spring.io/browse/SPR).
+Master currently represents work toward Spring Framework 5.0. Please submit
+all pull requests there, even bug fixes and minor improvements. Backports to
+`4.3.x` will be considered on a case-by-case basis.

-#### Ticket Lifecycle

-When an issue is first created, it may not be assigned and will not have a fix version.
-Within a day or two, the issue is assigned to a specific committer and the target
-version is set to "Waiting for Triage". The committer will then review the issue, ask for
-further information if needed, and based on the findings, the issue is either assigned a fix
-version or rejected.
+### Use short branch names

-When a fix is ready, the issue is marked "Resolved" and may still be re-opened. Once a fix
-is released, the issue is permanently "Closed". If necessary, you will need to create a new,
-related ticket with a fresh description.
+Branches used when submitting pull requests should preferably be named
+according to JIRA issues, e.g. 'SPR-1234'. Otherwise, use succinct, lower-case,
+dash (-) delimited names, such as 'fix-warnings', 'fix-typo', etc. In
+[fork-and-edit][] cases, the GitHub default 'patch-1' is fine as well. This is
+important, because branch names show up in the merge commits that result from
+accepting pull requests and should be as expressive and concise as possible.

-#### Submit a Pull Request
+## Use Spring Framework Code Style

-You can contribute a source code change by submitting a pull request.
+The complete [Spring Framework Code Style][] reference is available on the wiki, but
+here's a quick summary:

-1. If you have not previously done so, please sign the
-[Contributor License Agreement](https://cla.pivotal.io/sign/spring). You will also be reminded
-automatically when you submit a pull request.
+### Mind the whitespace

-1. For all but the most trivial of contributions, please [create a ticket](#create-a-ticket).
-The purpose of the ticket is to understand and discuss the underlying issue or feature.
-We use the JIRA issue tracker as the preferred place of record for conversations and
-conclusions. In that sense discussions directly under a PR are more implementation detail
-oriented and transient in nature.
+Please carefully follow the whitespace and formatting conventions already
+present in the framework.

-1. Always check out the `master` branch and submit pull requests against it
-(for target version see [settings.gradle](settings.gradle)).
-Backports to prior versions will be considered on a case-by-case basis and reflected as
-the fix version in the issue tracker.
+1. Tabs, not spaces
+1. Unix (LF), not DOS (CRLF) line endings
+1. Eliminate all trailing whitespace
+1. Wrap Javadoc at 90 characters
+1. Aim to wrap code at 90 characters, but favor readability over wrapping
+1. Preserve existing formatting; i.e. do not reformat code for its own sake
+1. Search the codebase using `git grep` and other tools to discover common
+    naming conventions, etc.
+1. UTF-8 encoding for Java sources

-1. Use short branch names, preferably based on the JIRA issue (e.g. `SPR-1234`), or
-otherwise using succinct, lower-case, dash (-) delimited names, such as `fix-warnings'.

-1. Choose the granularity of your commits consciously and squash commits that represent
-multiple edits or corrections of the same logical change. See
-[Rewriting History section of Pro Git](https://git-scm.com/book/en/Git-Tools-Rewriting-History)
-for an overview of streamlining commit history.
+### Add Apache license header to all new classes

-1. Format commit messages using 55 characters for the subject line, 72 lines for the
-description, followed by related issues, e.g. `Issues: SPR-1234, SPR-1235`.
-See the
-[Commit Guidelines section of Pro Git](https://git-scm.com/book/en/Distributed-Git-Contributing-to-a-Project#Commit-Guidelines)
-for best practices around commit messages and use `git log` to see some examples.

+ * limitations under the License.
+ */

-1. List the JIRA issue number in the PR description.
+package ...;
+```

-If accepted, your contribution may be heavily modified as needed prior to merging.
-You will likely retain author attribution for your Git commits granted that the bulk of
-your changes remain intact. You may also be asked to rework the submission.
+### Update Apache license header in modified files as necessary

-If asked to make corrections, simply push the changes against the same branch, and your
-pull request will be updated. In other words, you do not need to create a new pull request
-when asked to make changes.
+Always check the date range in the license header. For example, if you've
+modified a file in 2017 whose header still reads:

-### Build from Source
+```java
+/*
+ * Copyright 2002-2011 the original author or authors.
+```

-See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source)
-wiki page for instructions on how to check out, build, and import the Spring Framework
-source code into your IDE.
+Then be sure to update it to 2017 accordingly:

-### Source Code Style
+```java
+/*
+ * Copyright 2002-2017 the original author or authors.
+```

-The wiki pages
-[Code Style](https://github.com/spring-projects/spring-framework/wiki/Code-Style) and
-[IntelliJ IDEA Editor Settings](https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings)
-defines the source file coding standards we use along with some IDEA editor settings we customize.
+### Use @since tags for newly-added public API types and methods

-### Reference Docs
+For example:

-The reference documentation is in the [src/docs/asciidoc](src/docs/asciidoc) directory and, in
-[Asciidoctor](https://asciidoctor.org/) format. For trivial changes, you may be able to browse,
-edit source files, and submit directly from Github.
+```java
+/**
+ * ...
+ *
+ * @author First Last
+ * @since 5.0
+ * @see ...
+ */
+```

-When making changes locally, use `./gradlew asciidoctor` and then browse the result under
-`build/asciidoc/html5/index.html`.
+## Prepare Your Commit

-Asciidoctor also supports live editing. For more details read
-[Editing AsciiDoc with Live Preview](https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/).
-Note that if you choose the
-[System Monitor](https://asciidoctor.org/docs/editing-asciidoc-with-live-preview/#using-a-system-monitor)
-option, you can find a Guardfile under `src/docs/asciidoc`.
+### Submit JUnit test cases for all behavior changes
+
+Search the codebase to find related tests and add additional `@Test` methods
+as appropriate. It is also acceptable to submit test cases on a per JIRA issue
+basis, for example:
+
+```java
+package org.springframework.beans.factory.support;
+
+/**
+ * Unit tests for SPR-8954, in which a custom {@link InstantiationAwareBeanPostProcessor}
+ * forces the predicted type of a FactoryBean, effectively preventing retrieval of the
+ * bean from calls to #getBeansOfType(FactoryBean.class). The implementation of
+ * {@link AbstractBeanFactory#isFactoryBean(String, RootBeanDefinition)} now ensures
+ * that not only the predicted bean type is considered, but also the original bean
+ * definition's beanClass.
+ *
+ * @author Chris Beams
+ */
+public class Spr8954Tests {
+
+    @Test
+    public void cornerSpr8954() {
+        // ...
+    }
+}
+```
+
+
+### Squash commits
+
+Use `git rebase --interactive --autosquash`, `git add --patch`, and other tools
+to "squash" multiple commits into a single atomic commit. In addition to the man
+pages for git, there are many resources online to help you understand how these
+tools work. The [Rewriting History section of Pro Git][] provides a good overview.
+
+
+### Use real name in git commits
+
+Please configure git to use your real first and last name for any commits you
+intend to submit as pull requests. For example, this is not acceptable:
+
+    Author: Nickname <user@mail.com>
+
+Rather, please include your first and last name, properly capitalized, as
+submitted against the Spring Individual Contributor License Agreement (ICLA):
+
+    Author: First Last <user@mail.com>
+
+This helps ensure traceability against the ICLA and also goes a long way to
+ensuring useful output from tools like `git shortlog` and others.
+
+You can configure this via the account admin area in GitHub (useful for
+fork-and-edit cases); _globally_ on your machine with
+
+    git config --global user.name "First Last"
+    git config --global user.email user@mail.com
+
+or _locally_ for the `spring-framework` repository only by omitting the
+'--global' flag:
+
+    cd spring-framework
+    git config user.name "First Last"
+    git config user.email user@mail.com
+
+
+### Format commit messages
+
+Please read and follow the [Commit Guidelines section of Pro Git][].
+
+Most importantly, please format your commit messages in the following way
+(adapted from the commit template in the link above):
+
+    Short (50 chars or less) summary of changes
+
+    More detailed explanatory text, if necessary. Wrap it to about 72
+    characters or so. In some contexts, the first line is treated as the
+    subject of an email and the rest of the text as the body. The blank
+    line separating the summary from the body is critical (unless you omit
+    the body entirely); tools like rebase can get confused if you run the
+    two together.
+
+    Further paragraphs come after blank lines.
+
+     - Bullet points are okay, too
+
+     - Typically a hyphen or asterisk is used for the bullet, preceded by a
+       single space, with blank lines in between, but conventions vary here
+
+    Issue: SPR-1234, SPR-1235
+
+
+1. Use imperative statements in the subject line, e.g. "Fix broken Javadoc link".
+1. Begin the subject line with a capitalized verb, e.g. "Add, Prune, Fix,
+    Introduce, Avoid, etc."
+1. Do not end the subject line with a period.
+1. Restrict the subject line to 50 characters or less if possible.
+1. Wrap lines in the body at 72 characters or less.
+1. Mention associated JIRA issue(s) at the end of the commit comment, prefixed
+    with "Issue: " as above.
+1. In the body of the commit message, explain how things worked before this
+    commit, what has changed, and how things work now.
+
+For examples of this style, issue a `git log --author=cbeams` in the
+`spring-framework` git repository. For convenience, here are several such commits:

+
+## Run the Final Checklist
+
+### Run all tests prior to submission
+
+See the [building from source][] section of the `README` for instructions. Make
+sure that all tests pass prior to submitting your pull request.
+
+
+### Submit your pull request
+
+Subject line:
+
+Follow the same conventions for pull request subject lines as mentioned above
+for commit message subject lines.
+
+In the body:
+
+1. Explain your use case. What led you to submit this change? Why were existing
+    mechanisms in the framework insufficient? Make a case that this is a
+    general-purpose problem and that yours is a general-purpose solution, etc.
+1. Add any additional information and ask questions; start a conversation or
+    continue one from JIRA.
+1. Mention the JIRA issue ID.
+1. Also mention that you have submitted the ICLA as described above.
+
+Note that for pull requests containing a single commit, GitHub will default the
+subject line and body of the pull request to match the subject line and body of
+the commit message. This is fine, but please also include the items above in the
+body of the request.
+
+
+### Mention your pull request on the associated JIRA issue
+
+Add a comment to the associated JIRA issue(s) linking to your new pull request.
+
+
+### Expect discussion and rework
+
+The Spring team takes a very conservative approach to accepting contributions to
+the framework. This is to keep code quality and stability as high as possible,
+and to keep complexity at a minimum. Your changes, if accepted, may be heavily
+modified prior to merging. You will retain "Author:" attribution for your Git
+commits granted that the bulk of your changes remain intact. You may be asked to
+rework the submission for style (as explained above) and/or substance. Again, we
+strongly recommend discussing any serious submissions with the Spring Framework 
+team _prior_ to engaging in serious development work.
+
+Note that you can always force push (`git push -f`) reworked / rebased commits
+against the branch used to submit your pull request. In other words, you do not
+need to issue a new pull request when asked to make changes.

+## Spring Framework
+The Spring Framework provides a comprehensive programming and configuration
+model for modern Java-based enterprise applications -- on any kind of deployment
+platform. A key element of Spring is infrastructural support at the application
+level: Spring focuses on the "plumbing" of enterprise applications so that teams
+can focus on application-level business logic, without unnecessary ties to
+specific deployment environments.

-This is the home of the Spring Framework, the foundation for all
-[Spring projects](https://spring.io/projects). Together the Spring Framework and the family of Spring projects make up what we call "Spring". 
-
-Spring provides everything you need beyond the Java language to create enterprise
-applications in a wide range of scenarios and architectures. Please read the
-[Overview](https://docs.spring.io/spring/docs/current/spring-framework-reference/overview.html#spring-introduction)
-section in the reference for a more complete introduction.
+The framework also serves as the foundation for [Spring Integration][], [Spring Batch][]
+and the rest of the Spring [family of projects][]. Browse the repositories under
+the [Spring organization][] on GitHub for a full list.
