+# Contributing
+
+- Love your input! Contributing to this project should be as easy and transparent as possible, whether it's:
+  - Reporting a bug
+  - Discussing the current state of the code
+  - Submitting a fix
+  - Proposing new features
+  - Becoming a maintainer
+
+## Pull Request Process
+
+- [GitHub flow](https://guides.github.com/introduction/flow/index.html) is used
+- Your pull requests are actively welcomed.
+- The steps:
+  1. Fork the repo and create your branch from master.
+  2. If you've added code that should be tested, add tests.
+  3. If you've changed APIs, update the documentation.
+  4. Ensure the test suite passes.
+  5. Make sure your code lints.
+  6. Issue that pull request!
+- 🙏 DO
+  - Document your changes in the pull request
+- ❗ DON'T
+  - Do not update the versions, current version is only [set by the maintainer](./img/architecture/gitops.png) and updated automatically by [bump-everywhere](https://github.com/undergroundwires/bump-everywhere)
+
+## Guidelines
+
+### Handle the state in presentation layer
+
+- There are two types of components:
+  - **Stateless**, extends `Vue`
+  - **Stateful**, extends [`StatefulVue`](./src/presentation/StatefulVue.ts)
+    - The source of truth for the state lies in application layer (`./src/application/`) and must be updated from the views if they're mutating the state
+    - They mutate or/and reacts to changes in [application state](src/application/State/ApplicationState.ts).
+    - You can react by getting the state and listening to it and update the view accordingly in [`mounted()`](https://vuejs.org/v2/api/#mounted) method.

   - **Application Layer**
     - Keeps the application state
       - The [state](src/application/State/ApplicationState.ts) is a mutable singleton & event producer.
     - The application is defined & controlled in a [single YAML file](src/application/application.yaml) (see [Data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming))

+# Application file
+
+- privacy.sexy is a data-driven application where it reads the necessary OS-specific logic from [`application.yaml`](./../src/application/application.yaml)
+- 💡 Best practices
+  - If you repeat yourself, try to utilize [YAML-defined functions](#function)
+  - Always try to add documentation and a way to revert a tweak in [scripts](#script)
+- 📖 Types in code: [`application.d.ts`](./../src/application/application.yaml.d.ts)
+
+## Objects
+
+### `Application`
+
+- Application file simply defines different categories and their scripts in a tree structure.
+- Application file also allows defining common [function](#function)s to be used throughout the application if you'd like different scripts to share same code.
+
+#### `Application` syntax
+
+- `actions: [` ***[`Category`](#Category)*** `, ... ]` **(required)**
+  - Each [category](#category) is rendered as different cards in card presentation.
+  - ❗ Application must consist of at least one category.
+- `functions: [` ***[`Function`](#Function)*** `, ... ]`
+  - Functions are optionally defined to re-use the same code throughout different scripts.
+
+### `Category`
+
+- Category has a parent that has tree-like structure where it can have subcategories or subscripts.
+- It's a logical grouping of different scripts and other categories.
+
+#### `Category` syntax
+
+- `category:` *`string`*  (**required**)
+  - Name of the category
+  - ❗ Must be unique throughout the application
+- `children: [` ***[`Category`](#category)*** `|` [***`Script`***](#Script) `, ... ]`  (**required**)
+  - ❗ Category must consist of at least one subcategory or script.
+  - Children can be combination of scripts and subcategories.
+
+### `Script`
+
+- Script represents a single tweak.
+- A script must include either:
+  - A `code` and `revertCode`
+  - Or `call` to call YAML-defined functions
+- 🙏 For any new script, please add `revertCode` and `docs` values if possible.
+
+#### `Script` syntax
+
+- `name`: *`string`* (**required**)
+  - Name of the script
+  - ❗ Must be unique throughout the application
+  - E.g. `Disable targeted ads`
+- `code`: *`string`* (may be **required**)
+  - Batch file commands that will be executed
+  - 💡 If defined, best practice to also define `revertCode`
+  - ❗ If not defined `call` must be defined, do not define if `call` is defined.
+- `revertCode`: `string`
+  - Code that'll undo the change done by `code` property.
+  - E.g. let's say `code` sets an environment variable as `setx POWERSHELL_TELEMETRY_OPTOUT 1`
+    - then `revertCode` should be doing `setx POWERSHELL_TELEMETRY_OPTOUT 0`
+  - ❗ Do not define if `call` is defined.
+- `call`: ***[`FunctionCall`](#FunctionCall)*** | `[` ***[`FunctionCall`](#FunctionCall)*** `, ... ]` (may be **required**)
+  - A shared function or sequence of functions to call (called in order)
+  - ❗ If not defined `code` must be defined
+- `docs`: *`string`* | `[`*`string`*`, ... ]`
+  - Single documentation URL or list of URLs for those who wants to learn more about the script
+  - E.g. `https://docs.microsoft.com/en-us/windows-server/`
+- `recommend`: `"standard"` | `"strict"` | `undefined` (default)
+  - If not defined then the script will not be recommended
+  - If defined it can be either
+    - `standard`: Only non-breaking scripts without limiting OS functionality
+    - `strict`: Scripts that can break certain functionality in favor of privacy and security
+
+### `FunctionCall`
+
+- Describes a single call to a function by optionally providing values to its parameters.
+- 👀 See [parameter substitution](#parameter-substitution) for an example usage
+
+#### `FunctionCall` syntax
+
+- `function`: *`string`* (**required**)
+  - Name of the function to call.
+  - ❗ Function with same name must defined in `functions` property of [Application](#application)
+- `parameters`: `[ parameterName:` *`parameterValue`*`, ... ]`
+  - Defines key value dictionary for each parameter and its value
+  - E.g.
+
+    ```yaml
+      parameters:
+        userDefinedParameterName: parameterValue
+        # ...
+        appName: Microsoft.WindowsFeedbackHub
+    ```
+
+### `Function`
+
+- Functions allow re-usable code throughout the defined scripts.
+- Functions are templates compiled by privacy.sexy and uses special expressions.
+- Expressions are defined inside mustaches (double brackets, `{{` and `}}`)
+- 👀 See [parameter substitution](#parameter-substitution) for an example usage
+
+#### Parameter substitution
+
+A simple function example
+
+```yaml
+  function: EchoArgument
+  parameters: [ 'argument' ]
+  code: Hello {{ $argument }} !
+```
+
+It would print "Hello world" if it's called in a [script](#script) as following:
+
+```yaml
+  script: Echo script
+  call:
+    function: EchoArgument
+    parameters:
+      argument: World
+```
+
+#### `Function` syntax
+
+- `name`: *`string`* (**required**)
+  - Name of the function that scripts will use.
+  - Convention is to use camelCase, and be verbs.
+  - E.g. `uninstallStoreApp`
+  - ❗ Function names must be unique
+- `parameters`: `[` *`string`* `, ... ]`
+  - Name of the parameters that the function has.
+  - Parameter values are provided by a [Script](#script) through a [FunctionCall](#functioncall)
+  - Parameter names must be defined to be used in expressions such as [parameter substitution](#parameter-substitution)
+  - ❗ Parameter names must be unique
+ `code`: *`string`* (**required**)
+  - Batch file commands that will be executed
+  - 💡 If defined, best practice to also define `revertCode`
+- `revertCode`: *`string`*
+  - Code that'll undo the change done by `code` property.
+  - E.g. let's say `code` sets an environment variable as `setx POWERSHELL_TELEMETRY_OPTOUT 1`
+    - then `revertCode` should be doing `setx POWERSHELL_TELEMETRY_OPTOUT 0`
