+##### Built-in Formats
-  can be parsed.
+
+Open MCT on its own defines a handful of built-in formats:
+
+###### **Number Format (default):** 
+
+Applied to data with `format: 'number'`
+```js
+valueMetadata = {
+    format: 'number'
+    // ...
+};
+```
+
+```ts
+interface NumberFormatter extends Formatter {
+    parse: (x: any) => number;
+    format: (x: number) => string;
+    validate: (value: any) => boolean;
+}
+```
+###### **String Format**:
+
+Applied to data with `format: 'string'`
+```js
+valueMetadata = {
+    format: 'string'
+    // ...
+};
+```
+```ts
+interface StringFormatter extends Formatter {
+    parse: (value: any) => string;
+    format: (value: string) => string;
+    validate: (value: any) => boolean;
+}
+```
+
+###### **Enum Format**:
+Applied to data with `format: 'enum'`
+```js
+valueMetadata = {
+    format: 'enum',
+    enumerations: [
+    {
+        value: 1,
+        string: 'APPLE'
+    }, 
+    {
+        value: 2,
+        string: 'PEAR',
+    },
+    {
+        value: 3,
+        string: 'ORANGE'
+    }]
+    // ...
+};
+```
+
+Creates a two-way mapping between enum string and value to be used in the `parse` and `format` methods.
+Ex:
+- `formatter.parse('APPLE') === 1;`
+- `formatter.format(1) === 'APPLE';`
+
+```ts
+interface EnumFormatter extends Formatter {
+    parse: (value: string) => string;
+    format: (value: number) => string;
+    validate: (value: any) => boolean;
+}
+```
 
 ##### Registering Formats
 
+Formats implement the following interface (provided here as TypeScript for simplicity):
+
+
 Formats are registered with the Telemetry API using the `addFormat` function. eg.

+## Visibility-Based Rendering in View Providers
+
+To enhance performance and resource efficiency in OpenMCT, a visibility-based rendering feature has been added. This feature is designed to defer the execution of rendering logic for views that are not currently visible. It ensures that views are only updated when they are in the viewport, similar to how modern browsers handle rendering of inactive tabs but optimized for the OpenMCT tabbed display. It also works when views are scrolled outside the viewport (e.g., in a Display Layout).
+
+### Overview
+
+The show function is responsible for the rendering of a view. An [Intersection Observer](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API) is used internally to determine whether the view is visible. This observer drives the visibility-based rendering feature, accessed via the `renderWhenVisible` function provided in the `viewOptions` parameter.
+
+### Implementing Visibility-Based Rendering
+
+The `renderWhenVisible` function is passed to the show function as part of the `viewOptions` object. This function can be used for all rendering logic that would otherwise be executed within a `requestAnimationFrame` call. When called, `renderWhenVisible` will either execute the provided function immediately (via `requestAnimationFrame`) if the view is currently visible, or defer its execution until the view becomes visible.
+
+Additionally, `renderWhenVisible` returns a boolean value indicating whether the provided function was executed immediately (`true`) or deferred (`false`).
+
+Monitoring of visibility begins after the first call to `renderWhenVisible` is made.
+
+Here’s the signature for the show function:
+
+`show(element, isEditing, viewOptions)`
+
+  * `element` (HTMLElement) - The DOM element where the view should be rendered.
+  * `isEditing` (boolean) - Indicates whether the view is in editing mode.
+  * `viewOptions` (Object) - An object with configuration options for the view, including:
+    * `renderWhenVisible` (Function) - This function wraps the `requestAnimationFrame` and only triggers the provided render logic when the view is visible in the viewport.
+
+### Example
+
+An OpenMCT view provider might implement the show function as follows:
+
+```js
+// Define your view provider
+const myViewProvider = {
+  // ... other properties and methods ...
+  show: function (element, isEditing, viewOptions) {
+    // Callback for rendering view content
+    const renderCallback = () => {
+      // Your view rendering logic goes here
+    };
+    
+    // Use the renderWhenVisible function to ensure rendering only happens when view is visible
+    const wasRenderedImmediately = viewOptions.renderWhenVisible(renderCallback);
+
+    // Optionally handle the immediate rendering return value
+    if (wasRenderedImmediately) {
+      console.debug('🪞 Rendering triggered immediately as the view is visible.');
+    } else {
+      console.debug('🛑 Rendering has been deferred until the view becomes visible.');
+    }
+  }
+};
+```
+
+
+Note that `renderWhenVisible` defers rendering while the view is not visible and caters to the latest execution call. This provides responsiveness for dynamic content while ensuring performance optimizations.
+
+Ensure your view logic is prepared to handle potentially multiple deferrals if using this API, as only the last call to renderWhenVisible will be queued for execution upon the view becoming visible.

 Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. It is developed at NASA's Ames Research Center, and is being used by NASA for data analysis of spacecraft missions, as well as planning and operation of experimental rover systems. As a generalizable and open source framework, Open MCT could be used as the basis for building applications for planning, operation, and analysis of any systems producing telemetry data.

 ## Code Coverage
 
-* 100% statement coverage is achievable and desirable.
+It's up to the individual developer as to whether they want to add line coverage in the form of a unit test or e2e test.
 
-Codecov.io will combine each of the above commands with [Codecov.io Flags](https://docs.codecov.com/docs/flags). Effectively, this allows us to combine multiple reports which are run at various stages of our CI Pipeline or run as part of a parallel process.
+Line Code Coverage is generated by our unit tests and e2e tests, then combined by ([Codecov.io Flags](https://docs.codecov.com/docs/flags)), and finally reported in GitHub PRs by Codecov.io's PR Bot. This workflow gives a comprehensive (if flawed) view of line coverage.
+
+### Karma-istanbul
+
+Line coverage is generated by our `karma-coverage-istanbul-reporter` package as defined in our `karma.conf.js` file:
+
+```js
+    coverageIstanbulReporter: {
+      fixWebpackSourcePaths: true,
+      skipFilesWithNoCoverage: true,
+      dir: 'coverage/unit', //Sets coverage file to be consumed by codecov.io
+      reports: ['lcovonly']
+    },
+```
+
+Once the file is generated, it can be published to codecov with
+
+```json
+    "cov:unit:publish": "codecov --disable=gcov -f ./coverage/unit/lcov.info -F unit",
+```
+
+### e2e
+The e2e line coverage is a bit more complex than the karma implementation. This is the general sequence of events:
+
+1. Each e2e suite will start webpack with the ```npm run start:coverage``` command with config `webpack.coverage.js` and the `babel-plugin-istanbul` plugin to generate code coverage during e2e test execution using our custom [baseFixture](./baseFixtures.js). 
+1. During testcase execution, each e2e shard will generate its piece of the larger coverage suite. **This coverage file is not merged**. The raw coverage file is stored in a `.nyc_report` directory.
+1. [nyc](https://github.com/istanbuljs/nyc) converts this directory into a `lcov` file with the following command `npm run cov:e2e:report`
+1. Most of the tests are run in the '@stable' configuration and focus on chrome/ubuntu at a single resolution. This coverage is published to codecov with `npm run cov:e2e:stable:publish`.
+1. The rest of our coverage only appears when run against `@unstable` tests, persistent datastore (couchdb), non-ubuntu machines, and non-chrome browsers with the `npm run cov:e2e:full:publish` flag. Since this happens about once a day, we have leveraged codecov.io's carryforward flag to report on lines covered outside of each commit on an individual PR.
 
-This e2e coverage is combined with our unit test report to give a comprehensive (if flawed) view of line coverage.
 
 ### Limitations in our code coverage reporting
+Our code coverage implementation has some known limitations:
+- [Variability](https://github.com/nasa/openmct/issues/5811)
+- [Accuracy](https://github.com/nasa/openmct/issues/7015)

+## Troubleshooting CI
-- [Variability and accuracy](https://github.com/nasa/openmct/issues/5811)
+The following is an evolving guide to troubleshoot CI and PR issues.
-- [Vue instrumentation](https://github.com/nasa/openmct/issues/4973)
+
+### Github Checks failing
+There are a few reasons that your GitHub PR could be failing beyond simple failed tests.
+* Required Checks. We're leveraging required checks in GitHub so that we can quickly and precisely control what becomes and informational failure vs a hard requirement. The only way to determine the difference between a required vs information check is check for the `(Required)` emblem next to the step details in GitHub Checks.
+* Not all required checks are run per commit. You may need to manually trigger addition GitHub checks with a `pr:<label>` label added to your PR.
+
+### Flaky tests
+
+(CircleCI's test insights feature)[https://circleci.com/blog/introducing-test-insights-with-flaky-test-detection/] collects historical data about the individual test results for both unit and e2e tests. Note: only a 14 day window of flake is available.
+
+### Local=Pass and CI=Fail
+Although rare, it is possible that your test can pass locally but fail in CI.
+
+#### Busting Cache
+In certain circumstances, the CircleCI cache can become stale. In order to bust the cache, we've implemented a runtime boolean parameter in Circle CI creatively name BUST_CACHE. To execute:
+1. Navigate to the branch in Circle CI believed to have stale cache.
+1. Click on the 'Trigger Pipeline' button.
+1. Add Parameter -> Parameter Type = boolean , Name = BUST_CACHE ,Value = true
+1. Click 'Trigger Pipeline'
+
+#### Run tests in the same container as CI
+
+In extreme cases, tests can fail due to the constraints of running within a container. To execute tests in exactly the same way as run in CircleCI. 
+
+```sh
+// Replace {X.X.X} with the current Playwright version 
+// from our package.json or circleCI configuration file
+docker run --rm --network host --cpus="2" -v $(pwd):/work/ -w /work/ -it mcr.microsoft.com/playwright:v{X.X.X}-focal /bin/bash
+npm install
+```
+
+At this point, you're running inside the same container and with 2 cpu cores. You can specify the unit tests:
+```sh
+npm run test
+```
+or e2e tests:
+
+```sh
+npx playwright test --config=e2e/playwright-ci.config.js --project=chrome --grep <the testcase name>
+```

+# Release of NASA Open MCT NPM Package
+
+This document outlines the process and key considerations for releasing a new version of the NASA Open MCT project as an NPM (Node Package Manager) package.
+
+## 1. Pre-requisites
+
+Before releasing a new version of the NASA Open MCT NPM package, ensure all dependencies are updated, and comprehensive tests are performed. This ensures compatibility and performance of the Open MCT within the Node.js ecosystem.
+
+## 2. Versioning
+
+Versioning is a critical step for package release. The Open MCT team follows [Semantic Versioning (SemVer)](https://semver.org) that consists of three major components: MAJOR.MINOR.PATCH. These ensure a structured process for updating, bug fixes, backward compatibility, and software progress.
+
+## 3. Changelog Maintenance
+
+A comprehensive changelog file, `CHANGELOG.md`, documents any changes, adding a high level of transparencies for anyone desiring to look into the status of new and past progress. It includes the summation of any major new enhancements, changes, bug fixes, and the credits to the users responsible for each unique progress.
+
+## 4. Notable Changes Labels on GitHub PRs
+
+For the Open MCT package, we leverage GitHub's Pull Request (PR) mechanisms extensively, with three important PR labels dedicated to signifying 'notable_changes':
+
+- **Breaking Change** Highlights the integration of changes that are suspected to break, or without a doubt will break, backward compatibility. These should signal to users the upgrade might be seamless only if dependency and integration factors are properly managed, if not, one should expect to manage atypical technical snags.
+- **API change** Signifies when a contribution makes any complete or under layer changes to the communication or its supporting access processes. This label flags required see-through insight on how the web-based control panel sees and manipulates any value and or network logs.
+- **Default Behavior Change:** In the incident an update either adjusts a form to or integrates a not previously kept setting or plugin. i.e. autoscale is enabled by default when working with plots.
+
+## 6. Community & Contributions
+
+A flat community and the rounded center are kept in continuous celebration, with the given station open for two open-specifying dialogues, research, and all-for development probing. State the ownership for a handed looped, a welcome for even structure-core and architectural draft and impend.
+
+Thank you for your collaboration and commitment to moving the project onto a text big club.

+e2e testing describes the layer at which a test is performed without prescribing the assertions which are made. Generally, when writing an e2e test, we have five choices to make on an assertion strategy:
 
 1. Functional - Verifies the functional correctness of the application. Sometimes interchanged with e2e or regression testing.
 2. Visual - Verifies the "look and feel" of the application and can only detect _undesirable changes when compared to a previous baseline_.
 3. Snapshot - Similar to Visual in that it captures the "look" of the application and can only detect _undesirable changes when compared to a previous baseline_. **Generally not preferred due to advanced setup necessary.**
+4. Accessibility - Verifies that the application meets the accessibility standards defined by the [WCAG organization](https://www.w3.org/WAI/standards-guidelines/wcag/).
+5. Performance - Verifies that application provides a performant experience. Like Snapshot testing, these tests are generally not recommended due to their difficulty in providing a consistent result.
 
 When choosing between the different testing strategies, think only about the assertion that is made at the end of the series of test steps. "I want to verify that the Timer plugin functions correctly" vs "I want to verify that the Timer plugin does not look different than originally designed".

+## Automated Accessibility (a11y) Testing
+
+Open MCT incorporates accessibility testing through two primary methods to ensure its compliance with accessibility standards:
+
+1. **Usage of Playwright's Locator Strategy**: Open MCT utilizes Playwright's locator strategy, specifically the [page.getByRole('') function](https://playwright.dev/docs/api/class-framelocator#frame-locator-get-by-role), to ensure that web elements are accessible via assistive technologies. This approach focuses on the accessibility of elements rather than full adherence to a11y guidelines, which is covered in the second method.
+
+2. **Enforcing a11y Guidelines with Playwright Axe Plugin**: To rigorously enforce a11y guideline compliance, Open MCT employs the [playwright axe plugin](https://playwright.dev/docs/accessibility-testing). This is achieved through the `scanForA11yViolations` function within the visual testing suite. This method not only benefits from the existing coverage of the visual tests but also targets specific a11y issues, such as `color-contrast` violations, which are particularly pertinent in the context of visual testing.
+
+### a11y Standards (WCAG and Section 508)
+
+Playwright axe supports a wide range of [WCAG Standards](https://playwright.dev/docs/accessibility-testing#scanning-for-wcag-violations) to test against. Open MCT is testing against the [Section 508](https://www.section508.gov/test/testing-overview/) accessibility guidelines with the intent to support higher standards over time. As of 2024, Section508 requirements now map completely to WCAG 2.0 AA. In the future, Section 508 requirements may map to WCAG 2.1 AA.
+
+### Reading an a11y test failure
+
+When an a11y test fails, the result must be interpreted in the html test report or the a11y report json artifact stored in the `/test-results/` folder. The json structure should be parsed for `"violations"` by `"id"` and identified `"target"`. Example provided for the 'color-contrast-enhanced' violation.
+
+```json
+  "violations": 
+    {
+      "id": "color-contrast-enhanced",
+      "impact": "serious",
+      "html": "<span class=\"label c-indicator__label\">0 Snapshots <button aria-label=\"Show Snapshots\">Show</button></span>",

+##### Utilizing LocalStorage
+  1. In order to save test runtime in the case of tests that require a decent amount of initial setup (such as in the case of testing complex displays), you may use [Playwright's `storageState` feature](https://playwright.dev/docs/api/class-browsercontext#browser-context-storage-state) to generate and load localStorage states.
+  1. To generate a localStorage state to be used in a test:
+    - Add an e2e test to our generateLocalStorageData suite which sets the initial state (creating/configuring objects, etc.), saving it in the `test-data` folder:
+    ```js
+    // Save localStorage for future test execution
+    await context.storageState({
+      path: path.join(__dirname, '../../../e2e/test-data/display_layout_with_child_layouts.json')
+    });
+    ```
+    - Load the state from file at the beginning of the desired test suite (within the `test.describe()`). (NOTE: the storage state will be used for each test in the suite, so you may need to create a new suite):
+    ```js
+      const LOCALSTORAGE_PATH = path.resolve(
