-# Encryption
-
-Based on https://github.com/circleci/encrypted-files
-
-In the CircleCI web UI, we have a secret variable called `KEY`
-https://circleci.com/gh/angular/angular/edit#env-vars
-which is only exposed to non-fork builds
-(see "Pass secrets to builds from forked pull requests" under
-https://circleci.com/gh/angular/angular/edit#advanced-settings)
-
-We use this as a symmetric AES encryption key to encrypt tokens like
-a GitHub token that enables publishing snapshots.
-
-To create the github_token file, we take this approach:
-- Find the angular-builds:token in the internal pw database
-- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime: `docker run --rm -it circleci/node:10.12`
-- echo "https://[token]:@github.com" > credentials
-- openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
-- If needed, base64-encode the result so you can copy-paste it out of docker: `base64 github_token`

-# the default `bash` shell).
-#
-# See also https://circleci.com/docs/2.0/env-vars/#using-bash_env-to-set-environment-variables.

-#   `setPublicVar_<name>`.
-# - `<code>`: The code to run to compute the value for the variable. Since this code should be

- * Triggers a notification webhook with CircleCI specific info.

- * It can be used for notifying external servers and trigger operations based on CircleCI job status
- * (e.g. triggering the creation of a preview based on previously stored build atrifacts).
- *
- * The body of the sent payload is of the form:
- * ```json

- *     "build_num": ${buildNumber}
- *     "build_parameters": {

- * {
- *   "statucCode": ${statusCode},
- *   "responseText": "${responseText}"

- * ```
- *
- * NOTE:
- * - When used from the cli, the command will exit with an error code if the response's status code
- *   is outside the [200, 400) range.
- * - When used from JS, the returned promise will be resolved, even if the response's status code is
- *   outside the [200, 400) range. It is up to the caller to decide how this should be handled.

-# VSCode Remote Development - Developing inside a Containers
-
-This folder contains configuration files that can be used to opt into working on this repository in a [Docker container](https://www.docker.com/resources/what-container) via [VSCode](https://code.visualstudio.com/)'s Remote Development feature (see below).
-
-Info on remote development and developing inside a container with VSCode:
-- [VSCode: Remote Development](https://code.visualstudio.com/docs/remote/remote-overview)
-- [VSCode: Developing inside a Container](https://code.visualstudio.com/docs/remote/containers)
-- [VSCode: Remote Development FAQ](https://code.visualstudio.com/docs/remote/faq)
-
-
-## Usage
-
-_Prerequisite: [Install Docker](https://docs.docker.com/install) on your local environment._
-
-To get started, read and follow the instuctions in [Developing inside a Container](https://code.visualstudio.com/docs/remote/containers). The [.devcontainer/](.) directory contains pre-configured `devcontainer.json` and `Dockerfile` files, which you can use to set up remote development with a docker container.
-
-In a nutshell, you need to:
-- Install the [Remote - Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension.
-- Copy [recommended-Dockerfile](./recommended-Dockerfile) to `Dockerfile` (and optionally tweak to suit your needs).
-- Copy [recommended-devcontainer.json](./recommended-devcontainer.json) to `devcontainer.json` (and optionally tweak to suit your needs).
-- Open VSCode and bring up the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette).
-- Type `Remote-Containers: Open Folder in Container` and choose your local clone of [angular/angular](https://github.com/angular/angular).
-
-The `.devcontainer/devcontainer.json` and `.devcontainer/Dockerfile` files are ignored by git, so you can have your own local versions. We may occasionally update the template files ([recommended-devcontainer.json](./recommended-devcontainer.json), [recommended-Dockerfile](./recommended-Dockerfile)), in which case you will need to manually update your local copies (if desired).
-
-
-## Updating `recommended-devcontainer.json` and `recommended-Dockerfile`
-
-You can update and commit the recommended config files (which people use as basis for their local configs), if you find that something is broken, out-of-date or can be improved.
-
-Please, keep in mind that any changes you make will potentially be used by many people on different environments. Try to keep these config files cross-platform compatible and free of personal preferences.

-
-# ─── Example: A bug fix ──────────────────────────────────────────────────────────────────────────┤
-# fix(ngcc): ensure lockfile is removed when `analyzeFn` fails
-#
-# Previously an error thrown in the `analyzeFn` would cause the ngcc process to exit immediately
-# without removing the lockfile, and potentially before the unlocker process had been successfully
-# spawned resulting in the lockfile being orphaned and left behind.
-#
-# Now we catch these errors and remove the lockfile as needed.

-# ─── Example: Breaking change ────────────────────────────────────────────────────────────────────┤
-# feat(bazel): simplify ng_package by dropping esm5 and fesm5
-#
-# esm5 and fesm5 distributions are no longer needed and have been deprecated in the past.
-#
-# https://v9.angular.io/guide/deprecations#esm5-and-fesm5-code-formats-in-angular-npm-packages
-#
-# This commit modifies ng_package to no longer distribute these two formats in npm packages built by
-# ng_package (e.g. @angular/core).
-#
-# This commit intentionally doesn't fully clean up the ng_package rule to remove all traces of esm5
-# and fems5 build artifacts as that is a bigger cleanup and currently we are narrowing down the
-# scope of this change to the MVP needed for v10, which in this case is 'do not put esm5 and fesm5'
-# into the npm packages.
-#
-# More cleanup to follow: https://angular-team.atlassian.net/browse/FW-2143
-#
-# BREAKING CHANGE: esm5 and fesm5 format is no longer distributed in Angular's npm packages e.g.
-# @angular/core
-#
-# Angular CLI will automatically downlevel the code to es5 if differential loading is enabled in the
-# Angular project, so no action is required from Angular CLI users.
-#
-# If you are not using Angular CLI to build your application or library, and you need to be able to
-# build es5 artifacts, then you will need to downlevel the distributed Angular code to es5 on your
-# own.
-#
-#
-# Fixes #1234

-# VSCode Configuration
-
-This folder contains opt-in [Workspace Settings](https://code.visualstudio.com/docs/getstarted/settings), [Tasks](https://code.visualstudio.com/docs/editor/tasks), [Launch Configurations](https://code.visualstudio.com/Docs/editor/debugging#_launch-configurations) and [Extension Recommendations](https://code.visualstudio.com/docs/editor/extension-gallery#_workspace-recommended-extensions) that the Angular team recommends using when working on this repository.
-
-## Usage
-
-To use the recommended configurations follow the steps below:
-
-- install the recommneded extensions in `.vscode/extensions.json`
-- copy (or link) `.vscode/recommended-settings.json` to `.vscode/settings.json`
-- copy (or link) `.vscode/recommended-launch.json` to `.vscode/launch.json`
-- copy (or link) `.vscode/recommended-tasks.json` to `.vscode/tasks.json`
-- restart the editor
-
-If you already have your custom workspace settings you should instead manually merge the file contents.
-
-This isn't an automatic process so you will need to repeat it when settings are updated.
-
-To see the recommended extensions select "Extensions: Show Recommended Extensions" in the [Command Palette](https://code.visualstudio.com/docs/getstarted/userinterface#_command-palette).
-
-## Editing `.vscode/recommended-*.json` files
-
-If you wish to add extra configuration items please keep in mind any modifications you make here will be used by many users.
-
-Try to keep these settings/configuations to things that help facilitate the development process and avoid altering the user workflow whenever possible.

-To update to the latest version of Yarn as our vendored version:
-- Run this command

 ## <a name="question"></a> Got a Question or Problem?
 
-Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests.
-Instead, we recommend using [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) to ask support-related questions. When creating a new question on Stack Overflow, make sure to add the `angular` tag.
+Please, do not open issues for the general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) where the questions should be tagged with tag `angular`.
 
 Stack Overflow is a much better place to ask questions since:
 
 - there are thousands of people willing to help on Stack Overflow

 ### <a name="submit-issue"></a> Submitting an Issue
 
 Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
 
-We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it.
-In order to reproduce bugs, we require that you provide a minimal reproduction.
-Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.
+We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs we will systematically ask you to provide a minimal reproduction scenario using http://plnkr.co. Having a live, reproducible scenario gives us wealth of important information without going back & forth to you with additional questions like:
 
-A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
+- version of Angular used
+- 3rd-party libraries and their versions
+- and most importantly - a use-case that fails
 
-We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs.
-Often, developers find coding problems themselves while preparing a minimal reproduction.
-We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
+A minimal reproduce scenario using http://plnkr.co/ allows us to quickly confirm a bug (or point out coding problem) as well as confirm that we are fixing the right problem. If plunker is not a suitable way to demonstrate the problem (for example for issues related to our npm packaging), please create a standalone git repository demonstrating the problem.
 
-Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.

-##### Updating the commit message
-
-A reviewer might often suggest changes to a commit message (for example, to add more context for a change or adhere to our [commit message guidelines](#commit)).
-In order to update the commit message of the last commit on your branch:
-
-1. Check out your branch:
-
-    ```shell
-    git checkout my-fix-branch
-    ```
-
-2. Amend the last commit and modify the commit message:
-
-    ```shell
-    git commit --amend
-    ```
-
-3. Push to your GitHub repository:
-
-    ```shell
-    git push --force-with-lease
-    ```
-
-> NOTE:<br />
-> If you need to update the commit message of an earlier commit, you can use `git rebase` in interactive mode.
-> See the [git docs](https://git-scm.com/docs/git-rebase#_interactive_mode) for more details.

 ## <a name="rules"></a> Coding Rules
 To ensure consistency throughout the source code, keep these rules in mind as you are working:
 
 * All features or bug fixes **must be tested** by one or more specs (unit-tests).
-* All public API methods **must be documented**.
-* We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at **100 characters**.
+* All public API methods **must be documented**. (Details TBC).

+## <a name="commit"></a> Commit Message Guidelines
 
+We have very precise rules over how our git commit messages can be formatted.  This leads to **more
+readable messages** that are easy to follow when looking through the **project history**.  But also,
+we use the git commit messages to **generate the Angular change log**.
 
-## <a name="commit"></a> Commit Message Format
-
-*This specification is inspired and supersedes the [AngularJS commit message format][commit-message-format].*
-
-We have very precise rules over how our Git commit messages must be formatted.
-This format leads to **easier to read commit history**.
-
-Each commit message consists of a **header**, a **body**, and a **footer**.
-
+### Commit Message Format
+Each commit message consists of a **header**, a **body** and a **footer**.  The header has a special
+format that includes a **type**, a **scope** and a **subject**:
 
 ```
-<header>
+<type>(<scope>): <subject>
 <BLANK LINE>
 <body>
 <BLANK LINE>
 <footer>
 ```
 
-The `header` is mandatory and must conform to the [Commit Message Header](#commit-header) format.
+The **header** is mandatory and the **scope** of the header is optional.
 
-The `body` is mandatory for all commits except for those of scope "docs".
-When the body is required it must be at least 20 characters long.
+Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
+to read on GitHub as well as in various git tools.
 
-The `footer` is optional.
+Footer should contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages/) if any.
 
-Any line of the commit message cannot be longer than 100 characters.
-

-The `<type>` and `<summary>` fields are mandatory, the `(<scope>)` field is optional.
-
-
-##### Type
+### Revert
+If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
 
+### Type
 Must be one of the following:
 
 * **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
-* **ci**: Changes to our CI configuration files and scripts (example scopes: Circle, BrowserStack, SauceLabs)
+* **ci**: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
 * **docs**: Documentation only changes
 * **feat**: A new feature
 * **fix**: A bug fix
 * **perf**: A code change that improves performance
 * **refactor**: A code change that neither fixes a bug nor adds a feature
+* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
 * **test**: Adding missing tests or correcting existing tests
 
-
-##### Scope
-The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages).
+### Scope

 There are currently a few exceptions to the "use package name" rule:
 
-* `packaging`: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
+* **packaging**: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
+* **changelog**: used for updating the release notes in CHANGELOG.md
+* **aio**: used for docs-app (angular.io) related changes within the /aio directory of the repo
+* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all packages (e.g. `style: add missing semicolons`)
 
-* `changelog`: used for updating the release notes in CHANGELOG.md
-
-* `dev-infra`: used for dev-infra related changes within the directories /scripts, /tools and /dev-infra
-
-* `docs-infra`: used for docs-app (angular.io) related changes within the /aio directory of the repo
-
-* `migrations`: used for changes to the `ng update` migrations.
-
-* `ngcc`: used for changes to the [Angular Compatibility Compiler](./packages/compiler-cli/ngcc/README.md)
-
-* `ve`: used for changes specific to ViewEngine (legacy compiler/renderer).
-
-* none/empty string: useful for `test` and `refactor` changes that are done across all packages (e.g. `test: add missing unit tests`) and for docs changes that are not related to a specific package (e.g. `docs: fix typo in tutorial`).
-
-
-##### Summary
-
-Use the summary field to provide a succinct description of the change:
+### Subject
+The subject contains succinct description of the change:
 
 * use the imperative, present tense: "change" not "changed" nor "changes"
-* don't capitalize the first letter
+* don't capitalize first letter
 * no dot (.) at the end
 
+### Body
+Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
+The body should include the motivation for the change and contrast this with previous behavior.
 
-#### Commit Message Body
+### Footer
+The footer should contain any information about **Breaking Changes** and is also the place to
+reference GitHub issues that this commit **Closes**.
 
-Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".
-
-Explain the motivation for the change in the commit message body. This commit message should explain _why_ you are making the change.
-You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.
-
-
-#### Commit Message Footer
-
-The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.
-
-```
-BREAKING CHANGE: <breaking change summary>
-<BLANK LINE>
-<breaking change description + migration instructions>
-<BLANK LINE>
-<BLANK LINE>
-Fixes #<issue number>
-```
-
-Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
-
-
-### Revert commits
-
-If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit.
-
-The content of the commit message body should contain:
-
-- information about the SHA of the commit being reverted in the following format: `This reverts commit <SHA>`,
-- a clear description of the reason for reverting the commit message.
+**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
 
+A detailed explanation can be found in this [document][commit-message-format].

 * `yarn start` - run a development web server that watches the files; then builds the doc-viewer and reloads the page, as necessary.
 * `yarn serve-and-sync` - run both the `docs-watch` and `start` in the same console.
 * `yarn lint` - check that the doc-viewer code follows our style rules.
 * `yarn test` - watch all the source files, for the doc-viewer, and run all the unit tests when any change.

-> Setting up the examples involves creating some [symbolic links](https://en.wikipedia.org/wiki/Symbolic_link) (see [here](./tools/examples/README.md#symlinked-node_modules) for details). On Windows, this requires to either have [Developer Mode enabled](https://blogs.windows.com/windowsdeveloper/2016/12/02/symlinks-windows-10) (supported on Windows 10 or newer) or run the setup commands as administrator.

 ## Using ServiceWorker locally
 
-Running `yarn start` (even when explicitly targeting production mode) does not set up the
-ServiceWorker. If you want to test the ServiceWorker locally, you can use `yarn build` and then
-serve the files in `dist/` with `yarn http-server dist -p 4200`.
+Since abb36e3cb, running `yarn start -- --prod` will no longer set up the ServiceWorker, which
+would require manually running `yarn sw-manifest` and `yarn sw-copy` (something that is not possible
+with webpack serving the files from memory).
