-Polyfill for [RFC 566 "@cached decorator"][rfc-566].
-
-[rfc-566]: https://github.com/emberjs/rfcs/pull/566
-
-## Installation
-
-```bash
-ember install ember-cached-decorator-polyfill
-```
-
-For addons, pass the `-S` flag.
-
-## Compatibility
-
-* Ember.js v3.13 or above
-* Ember CLI v2.13 or above
-* Node.js v10 or above
-
-## Summary
-
-Add a `@cached` decorator for memoizing the result of a getter based on
-autotracking. In the following example, `fullName` would only recalculate if
-`firstName` or `lastName` is updated.
-
-```js
-import { tracked, cached } from '@glimmer/tracking';
-
-class Person {
-  @tracked firstName = 'Jen';
-  @tracked lastName = 'Weber';
-
-  @cached
-  get fullName() {
-    return `${this.firstName} ${this.lastName}`;
-  }
-}
-```
-
-For detailed usage instructions, refer to the
-[RFC 566 "@cached decorator"][rfc-566].
-
-## TypeScript Usage
-
-TypeScript's normal type resolution for an import from `@glimmer/tracking`
-will **not** find this the types provided by this package (since TypeScript
-would attempt to resolve it as `node_modules/@glimmer/tracking` or under
-the Definitely Typed location for `@glimmer/tracking`).
-
-Once the addition to the `@glimmer/tracking` API is a documented part of Ember's
-API, the types will be available upstream, but in the meantime users will need
-to modify their `tsconfig.json` to tell TypeScript where these types are.
-
-Add the following to your `tsconfig.json`:
-
-```js
-{
-  // ...snip...
-  "paths": {
-    // ...snip...
-    "@glimmer/tracking": [
-      "node_modules/ember-cached-decorator-polyfill",
-      "node_modules/@glimmer/tracking/dist/types"
-    ],
-  }
-}

-# Release
-
-Releases are mostly automated using
-[release-it](https://github.com/release-it/release-it/) and
-[lerna-changelog](https://github.com/lerna/lerna-changelog/).
-
-
-## Preparation
-
-Since the majority of the actual release process is automated, the primary
-remaining task prior to releasing is confirming that all pull requests that
-have been merged since the last release have been labeled with the appropriate
-`lerna-changelog` labels and the titles have been updated to ensure they
-represent something that would make sense to our users. Some great information
-on why this is important can be found at
-[keepachangelog.com](https://keepachangelog.com/en/1.0.0/), but the overall
-guiding principle here is that changelogs are for humans, not machines.
-
-When reviewing merged PR's the labels to be used are:
-
-* breaking - Used when the PR is considered a breaking change.
-* enhancement - Used when the PR adds a new feature or enhancement.
-* bug - Used when the PR fixes a bug included in a previous release.
-* documentation - Used when the PR adds or updates documentation.
-* internal - Used for internal changes that still require a mention in the
-  changelog/release notes.
-
-
-## Release
-
-Once the prep work is completed, the actual release is straight forward:
-
-* First, ensure that you have installed your projects dependencies:
-
-```
-yarn install
-```
-
-* Second, ensure that you have obtained a
-  [GitHub personal access token][generate-token] with the `repo` scope (no
-  other permissions are needed). Make sure the token is available as the
-  `GITHUB_AUTH` environment variable.
-
-  For instance:
-
-  ```bash
-  export GITHUB_AUTH=abc123def456
-  ```
-
-[generate-token]: https://github.com/settings/tokens/new?scopes=repo&description=GITHUB_AUTH+env+variable
-
-* And last (but not least 😁) do your release.
-
-```
-npx release-it
-```
-
-[release-it](https://github.com/release-it/release-it/) manages the actual
-release process. It will prompt you to to choose the version number after which
-you will have the chance to hand tweak the changelog to be used (for the
-`CHANGELOG.md` and GitHub release), then `release-it` continues on to tagging,
-pushing the tag and commits, etc.

+# Release
+
+Releases are mostly automated using
+[release-it](https://github.com/release-it/release-it/) and
+[lerna-changelog](https://github.com/lerna/lerna-changelog/).
+
+
+## Preparation
+
+Since the majority of the actual release process is automated, the primary
+remaining task prior to releasing is confirming that all pull requests that
+have been merged since the last release have been labeled with the appropriate
+`lerna-changelog` labels and the titles have been updated to ensure they
+represent something that would make sense to our users. Some great information
+on why this is important can be found at
+[keepachangelog.com](https://keepachangelog.com/en/1.0.0/), but the overall
+guiding principle here is that changelogs are for humans, not machines.
+
+When reviewing merged PR's the labels to be used are:
+
+* breaking - Used when the PR is considered a breaking change.
+* enhancement - Used when the PR adds a new feature or enhancement.
+* bug - Used when the PR fixes a bug included in a previous release.
+* documentation - Used when the PR adds or updates documentation.
+* internal - Used for internal changes that still require a mention in the
+  changelog/release notes.
+
+
+## Release
+
+Once the prep work is completed, the actual release is straight forward:
+
+* First, ensure that you have installed your projects dependencies:
+
+```
+yarn install
+```
+
+* Second, ensure that you have obtained a
+  [GitHub personal access token][generate-token] with the `repo` scope (no
+  other permissions are needed). Make sure the token is available as the
+  `GITHUB_AUTH` environment variable.
+
+  For instance:
+
+  ```bash
+  export GITHUB_AUTH=abc123def456
+  ```
+
+[generate-token]: https://github.com/settings/tokens/new?scopes=repo&description=GITHUB_AUTH+env+variable
+
+* And last (but not least 😁) do your release.
+
+```
+npx release-it
+```
+
+[release-it](https://github.com/release-it/release-it/) manages the actual
+release process. It will prompt you to to choose the version number after which
+you will have the chance to hand tweak the changelog to be used (for the
+`CHANGELOG.md` and GitHub release), then `release-it` continues on to tagging,
+pushing the tag and commits, etc.
