 #### Telemetry Formats
 
 Telemetry format objects define how to interpret and display telemetry data.
-They have a simple structure:
+They have a simple structure, provided here as a TypeScript interface:
 
-- `key`: A `string` that uniquely identifies this formatter.
-- `format`: A `function` that takes a raw telemetry value, and returns a
-  human-readable `string` representation of that value. It has one required
-  argument, and three optional arguments that provide context and can be used
-  for returning scaled representations of a value. An example of this is
-  representing time values in a scale such as the time conductor scale. There
-  are multiple ways of representing a point in time, and by providing a minimum
-  scale value, maximum scale value, and a count, it's possible to provide more
-  useful representations of time given the provided limitations.  
-  - `value`: The raw telemetry value in its native type.
-  - `minValue`: An **optional** argument specifying the minimum displayed
-      value.
-  - `maxValue`: An **optional** argument specifying the maximum displayed
-      value.
-  - `count`: An **optional** argument specifying the number of displayed
-      values.
-- `parse`: A `function` that takes a `string` representation of a telemetry
-  value, and returns the value in its native type. **Note** parse might receive an already-parsed value.  This function should be idempotent.
-- `validate`: A `function` that takes a `string` representation of a telemetry
-  value, and returns a `boolean` value indicating whether the provided string
-  can be parsed.
+```ts
+interface Formatter {
+    key: string; // A string that uniquely identifies this formatter.
+
+    format: (
+        value: any, // The raw telemetry value in its native type.
+        minValue?: number, // An optional argument specifying the minimum displayed value.
+        maxValue?: number, // An optional argument specifying the maximum displayed value.
+        count?: number // An optional argument specifying the number of displayed values.
+    ) => string; // Returns a human-readable string representation of the provided value.
+
+    parse: (
+        value: string | any // A string representation of a telemetry value or an already-parsed value.
+    ) => any; // Returns the value in its native type. This function should be idempotent.
+
+    validate: (value: string) => boolean; // Takes a string representation of a telemetry value and returns a boolean indicating whether the provided string can be parsed.
+}
+```
+
+##### Built-in Formats
+
+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.

 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.

+## Troubleshooting CI
+The following is an evolving guide to troubleshoot CI and PR issues.
+
+### 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
+There are two ways to know if a test on your branch is historically flaky: 
+1. `deploysentinel`'s PR comment bot to give an accurate and historical view of e2e flakiness. Check your PR for a view of the test failures and flakes (with link to the failing test). Note: only a 7 day window of flake is available.
+2. (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>
+```

   1.  Avoid repeated setup to test a single assertion. Write longer tests with multiple soft assertions.
   This ensures that your changes will be picked up with large refactors.
 
+##### 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(
+        __dirname,
+        '../../../../test-data/display_layout_with_child_layouts.json'
+      );
+      test.use({
+        storageState: path.resolve(__dirname, LOCALSTORAGE_PATH)
+      });
