 ### Code Standards
 
-JavaScript sources in Open MCT must satisfy JSLint under its default
-settings. This is verified by the command line build.
+JavaScript sources in Open MCT must satisfy the ESLint rules defined in 
+this repository. This is verified by the command line build.
 
 #### Code Guidelines
 
-JavaScript sources in Open MCT should:
-
-* Use four spaces for indentation. Tabs should not be used.
-* Include JSDoc for any exposed API (e.g. public methods, constructors).
-* Include non-JSDoc comments as-needed for explaining private variables,
-  methods, or algorithms when they are non-obvious.
-* Define one public class per script, expressed as a constructor function
-  returned from an AMD-style module.
-* Follow “Java-like” naming conventions. These includes:
-  * Classes should use camel case, first letter capitalized
-    (e.g. SomeClassName).
-  * Methods, variables, fields, and function names should use camel case,
-    first letter lower-case (e.g. someVariableName).
-  * Constants (variables or fields which are meant to be declared and 
-    initialized statically, and never changed) should use only capital 
-    letters, with underscores between words (e.g. SOME_CONSTANT).
-  * File names should be the name of the exported class, plus a .js extension
-    (e.g. SomeClassName.js).
-* Avoid anonymous functions, except when functions are short (a few lines)
-  and/or their inclusion makes sense within the flow of the code
-  (e.g. as arguments to a forEach call).
-* Avoid deep nesting (especially of functions), except where necessary
-  (e.g. due to closure scope).
-* End with a single new-line character.
-* Expose public methods by declaring them on the class's prototype.
-* Within a given function's scope, do not mix declarations and imperative
-  code, and  present these in the following order:
-  * First, variable declarations and initialization.
-  * Second, function declarations.
-  * Third, imperative statements.
-  * Finally, the returned value.
+The following guidelines are provided for anyone contributing source code to the Open MCT project:
 
+1. Write clean code. Here’s a good summary - https://github.com/ryanmcdermott/clean-code-javascript.
+1. Include JSDoc for any exposed API (e.g. public methods, classes).
+1. Include non-JSDoc comments as-needed for explaining private variables,
+   methods, or algorithms when they are non-obvious. Otherwise code 
+   should be self-documenting.
+1. Classes and Vue components should use camel case, first letter capitalized
+   (e.g. SomeClassName).
+1. Methods, variables, fields, events, and function names should use camelCase,
+   first letter lower-case (e.g. someVariableName).
+1. Source files that export functions should use camelCase, first letter lower-case (eg. testTools.js)
+1. Constants (variables or fields which are meant to be declared and 
+   initialized statically, and never changed) should use only capital 
+   letters, with underscores between words (e.g. SOME_CONSTANT). They should always be declared as `const`s
+1. File names should be the name of the exported class, plus a .js extension
+   (e.g. SomeClassName.js).
+1. Avoid anonymous functions, except when functions are short (one or two lines)
+   and their inclusion makes sense within the flow of the code
+   (e.g. as arguments to a forEach call). Anonymous functions should always be arrow functions.
+1. Named functions are preferred over functions assigned to variables.
+   eg.
+   ```JavaScript
+   function renameObject(object, newName) {
+       Object.name = newName;
+   }
+   ```
+   is preferable to
+   ```JavaScript
+   const rename = (object, newName) => {
+       Object.name = newName;
+   }
+   ```
+1. Avoid deep nesting (especially of functions), except where necessary
+   (e.g. due to closure scope).
+1. End with a single new-line character.
+1. Always use ES6 `Class`es and inheritence rather than the pre-ES6 prototypal 
+   pattern.
+1. Within a given function's scope, do not mix declarations and imperative
+   code, and  present these in the following order:
+   * First, variable declarations and initialization.
+   * Secondly, imperative statements.
+   * Finally, the returned value. A single return statement at the end of the function should be used, except where an early return would improve code clarity.
+1. Avoid the use of "magic" values.
+   eg.
+   ```JavaScript
+   Const UNAUTHORIZED = 401
+   if (responseCode === UNAUTHORIZED)
+   ```
+   is preferable to
+   ```JavaScript
+   if (responseCode === 401)
+   ```
+1. Use the ternary operator only for simple cases such as variable assignment. Nested ternaries should be avoided in all cases.
+1. Test specs should reside alongside the source code they test, not in a separate directory.
+1. Organize code by feature, not by type.
+   eg.
+   ```
+   - telemetryTable
+       - row
+           TableRow.js
+           TableRowCollection.js
+           TableRow.vue
+       - column
+           TableColumn.js
+           TableColumn.vue
+       plugin.js
+       pluginSpec.js
+   ```
+   is preferable to
+   ```
+   - telemetryTable
+       - components
+           TableRow.vue
+           TableColumn.vue
+       - collections
+           TableRowCollection.js
+       TableColumn.js
+       TableRow.js
+       plugin.js
+       pluginSpec.js
+   ```

+
+### Testathons
+Testathons can be used as a means of performing per-sprint and per-release testing. 
+
+#### Timing
+For per-sprint testing, a testathon is typically performed at the beginning of the third week of a sprint, and again later that week to verify any fixes. For per-release testing, a testathon is typically performed prior to any formal testing processes that are applicable to that release.
+
+#### Process
+
+1. Prior to the scheduled testathon, a list will be compiled of all issues that are closed and unverified.
+2. For each issue, testers should review the associated PR for testing instructions. See the contributing guide for instructions on [pull requests](https://github.com/nasa/openmct/blob/master/CONTRIBUTING.md#merging).
+3. As each issue is verified via testing, any team members testing it should leave a comment on that issue indicating that it has been verified fixed.
+4. If a bug is found that relates to an issue being tested, notes should be included on the associated issue, and the issue should be reopened. Bug notes should include reproduction steps.
+5. For any bugs that are not obviously related to any of the issues under test, a new issue should be created with details about the bug, including reproduction steps. If unsure about whether a bug relates to an issue being tested, just create a new issue.
+6. At the end of the testathon, triage will take place, where all tested issues will be reviewed.
+7. If verified fixed, an issue will remain closed, and will have the “unverified” label removed.
+8. For any bugs found, a severity will be assigned.
+9. A second testathon will be scheduled for later in the week that will aim to address all issues identified as blockers, as well as any other issues scoped by the team during triage.
+10. Any issues that were not tested will remain "unverified" and will be picked up in the next testathon.
