+## Extend scripts
+
+Here's quick information for you who want to add more scripts.
+
+You have two alternatives:
+
+1. [Create an issue](https://github.com/undergroundwires/privacy.sexy/issues/new/choose) and ask for someone else to add the script for you.
+2. Or send a PR yourself. This would make it faster to get your code into the project. You need to add scripts to related OS in [collections](src/application/collections/) folder. Then you'd sent a pull request, see [pull request process](#pull-request-process).
+   - 📖 If you're unsure about the syntax, check [collection-files.md](docs/collection-files.md).
+   - 📖 If you wish to use templates, use [templating.md](./docs/templating.md).

 ## Structure
 
-- [`/src/` **`application/`**](./../src/application/): Contains all application related code.
+Application layer code exists in [`/src/application`](./../src/application/) and includes following structure:
-  - [**`collections/`**](./../src/application/collections/): Holds [collection files](./collection-files.md)
+
-  - [**`Common/`**](./../src/application/Common/): Contains common functionality that is shared in application layer.
+- [**`collections/`**](./../src/application/collections/): Holds [collection files](./collection-files.md).

+- [**`Common/`**](./../src/application/Common/): Contains common functionality in application layer.
+- `...`: rest of the application layer source code organized using folders-by-feature structure.
 
 ## Application state
 
-- [ApplicationContext.ts](./../src/application/Context/ApplicationContext.ts) holds the [CategoryCollectionState](./../src/application/Context/State/CategoryCollectionState.ts) for each OS
+It uses [state pattern](https://en.wikipedia.org/wiki/State_pattern) with context and state objects. [`ApplicationContext.ts`](./../src/application/Context/ApplicationContext.ts) the "Context" of state pattern provides an instance of [`CategoryCollectionState.ts`](./../src/application/Context/State/CategoryCollectionState.ts) (the "State" of the state pattern) for every supported collection.
-- Uses [state pattern](https://en.wikipedia.org/wiki/State_pattern)
+
-- Same instance is shared throughout the application to ensure consistent state
+Presentation layer uses a singleton (same instance of) [`ApplicationContext.ts`](./../src/application/Context/ApplicationContext.ts) throughout the application to ensure consistent state.
-- 📖 See [Application State | Presentation layer](./presentation.md#application-state) to read more about how the state should be managed by the presentation layer.
+
-- 📖 See [ApplicationContext.ts](./../src/application/Context/ApplicationContext.ts) to start diving into the state code.
+📖 Refer to [architecture.md | Application State](./architecture.md#application-state) to get an overview of event handling and [presentation.md | Application State](./presentation.md#application-state) for deeper look into how the presentation layer manages state.
 
 ## Application data
 
-- Compiled to [`Application`](./../src/domain/Application.ts) domain object.
+Application data is collection files using YAML. You can refer to [collection-files.md](./collection-files.md) to read more about the scheme and structure of application data files. You can also check the source code [collection yaml files](./../src/application/collections/) to directly see the application data using that scheme.
-- The scripts are defined and controlled in different data files per OS
-- Enables [data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming) and easier contributions
-- Application data is defined in collection files and
-- 📖 See [Application data | Presentation layer](./presentation.md#application-data) to read how the application data is read by the presentation layer.
-- 📖 See [collection files documentation](./collection-files.md) to read more about how the data files are structured/defined and see [collection yaml files](./../src/application/collections/) to directly check the code.
 
-## Parsing
+Application layer [parses and compiles](#parsing-and-compiling) application data into [`Application`](./../src/domain/Application.ts)). Once parsed, application layer provides the necessary functionality to presentation layer based on the application data. You can read more about how presentation layer consumes the application data in [presentation.md | Application Data](./presentation.md#application-data).
 
-- Application data is parsed to domain object [`Application.ts`](./../src/domain/Application.ts)
+Application layer enables [data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming) by leveraging the data to the rest of the source code. It makes it easy for community to contribute on the project by using a declarative language used in collection files.
-- Steps
-  1. (Compile time) Load application data from [collection yaml files](./../src/application/collections/) using webpack loader
-  2. (Runtime) Parse and compile application and make it available to presentation layer by [`ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts)
 
-### Compiling
+### Parsing and compiling
+
+Application layer parses the application data to compile the domain object [`Application.ts`](./../src/domain/Application.ts).
+
+A webpack loader loads (or injects) application data ([collection yaml files](./../src/application/collections/)) into the application layer in compile time. Application layer ([`ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts)) parses and compiles this data in runtime.
+
+Application layer compiles templating syntax during parsing to create the end scripts. You can read more about templating syntax in [templating.md](./templating.md) and how application data uses them through functions in [collection-files.md | Function](./collection-files.md#function).
+
+The steps to extend the templating syntax:
 
-- Parsing the application files includes compiling scripts using [collection file defined functions](./collection-files.md#function)
-- To extend the syntax:
 1. Add a new parser under [SyntaxParsers](./../src/application/Parser/Script/Compiler/Expressions/SyntaxParsers) where you can look at other parsers to understand more.
-  2. Register your in [CompositeExpressionParser](./../src/application/Parser/Script/Compiler/Expressions/Parser/CompositeExpressionParser.ts)

+# Architecture overview
+
+This repository consists of:
+
+- A [layered application](#layered-application).
+- [AWS infrastructure](#aws-infrastructure) as code and instructions to host the website.
+- [GitOps](#gitops) practices for development, maintenance and deployment.
+
+## Layered application
+
+Application is
+
+- powered by **TypeScript**, **Vue.js** and **Electron** 💪,
+- and driven by **Domain-driven design**, **Event-driven architecture**, **Data-driven programming** concepts.
+
+Application uses highly decoupled models & services in different DDD layers:
+
+- presentation layer (see [presentation.md](./presentation.md)),
+- application layer (see [application.md](./application.md)),
+- and domain layer.
+
+Application layer depends on and consumes domain layer. [Presentation layer](./presentation.md) consumes and depends on application layer along with domain layer. Application and presentation layers can communicate through domain model.
+
+![DDD + vue.js](./../img/architecture/app-ddd.png)
+
+### Application state
+
+State handling uses an event-driven subscription model to signal state changes and special functions to register changes. It does not depend on third party packages.
+
+Each layer treat application layer differently.
+
+![State](./../img/architecture/app-state.png)
+
+*[Presentation layer](./presentation.md)*:
+
+- Each component holds their own state about presentation-related data.
+- Components register shared state changes into application state using functions.
+- Components listen to shared state changes using event subscriptions.
+- 📖 Read more: [presentation.md | Application state](./presentation.md#application-state).
+
+*[Application layer](./application.md)*:
+
+- Stores the application-specific state.
+- The state it exposed for read with getter functions and set using setter functions, setter functions also fire application events that allows other parts of application and the view in presentation layer to react.
+- So state is mutable, and fires related events when mutated.
+- 📖 Read more: [application.md | Application state](./application.md#application-state).
+
+It's comparable with flux ([`redux`](https://redux.js.org/)) or flux-like ([`vuex`](https://vuex.vuejs.org/)) patterns. Flux component "view" is [presentation layer](./presentation.md) in Vue. Flux functions "dispatcher", "store" and "action creation" functions lie in the [application layer](./application.md). A difference is that application state in privacy.sexy is mutable and lies in single flux "store" that holds app state and logic. The "actions" mutate the state directly which in turns act as dispatcher to notify its own event subscriptions (callbacks).
+
+## AWS infrastructure
+
+The web-site runs on serverless AWS infrastructure. Infrastructure is open-source and deployed as code. [aws-static-site-with-cd](https://github.com/undergroundwires/aws-static-site-with-cd) project includes the source code.
+
+[![AWS solution](../img/architecture/aws-solution.png)](https://github.com/undergroundwires/aws-static-site-with-cd)

+This project includes [GitHub Actions](../.github/workflows/) to automatically provision the infrastructure with zero-touch and without any "hidden" steps, ensuring everything is open-source and transparent.

+# CI/CD overview
+
+## GitOps
+
+CI/CD is fully automated using different Git events and GitHub actions. This repository uses [bump-everywhere](https://github.com/undergroundwires/bump-everywhere) to automate versioning, tagging, creation of `CHANGELOG.md` and GitHub releases. A dedicated workflow [release.desktop.yaml](./../.github/workflows/release.desktop.yaml) creates desktop installers and executables and attaches them into GitHub releases.
+
+Everything that's merged in the master goes directly to production.
+
+[![CI/CD using GitHub Actions](./../img/architecture/gitops.png)](../.github/workflows/)
+
+## Pipeline files
+
+privacy.sexy uses [GitHub actions](https://github.com/features/actions) to define and run pipelines as code.
+
+GitHub workflows i.e. pipelines exist in [`/.github/workflows/`](./../.github/workflows/) folder without any subfolders due to GitHub actions requirements [1] .
+
+Local GitHub actions are defined in [`/.github/actions/`](./../.github/actions/) and used to reuse same workflow steps.
+
+## Pipeline types
+
+We categorize pipelines into different categories. We use these names in convention when naming files and actions, see [naming conventions](#naming-conventions).
+
+The categories consist of:
+
+- `tests`: Different types of tests to verify functionality.
+- `checks`: Other controls such as vulnerability scans or styling checks.
+- `release`: Pipelines used for release of deployment such as building and testing.
+
+## Naming conventions
+
+Convention for naming pipeline files: **`<type>.<name>.yaml`**.
+
+**`type`**:
+
+- Sub-folders do not work for GitHub workflows [1] so we use `<type>.` prefix to organize them.
+- See also [pipeline types](#pipeline-types) for list of all usable types.
+
+**`name`**:
+
+- We name workflows using kebab-case.
+- E.g. file name `tests.unit.yaml`, pipeline file should set the naem as: `name: unit-tests`.
+- Kebab-case allows to have better URL references to them.
+  - [README.md](./../README.md) uses URL references to show status badges for actions.

+1. [Run unit tests](#testing)
+2. [Lint your code](#linting)
+
+You could run other types of tests as well, but they may take longer time and overkill for your changes. Automated actions executes the tests for a pull request or change in the main branch. See [ci-cd.md](./ci-cd.md) for more information.
+
+## Commands
+
+### Prerequisites
+
+- Install node >15.x.
+- Install dependencies using `npm install`.
+
+### Testing
+
+- Run unit tests: `npm run test:unit`
+- Run integration tests: `npm run test:integration`
+- Run e2e (end-to-end) tests
+  - Interactive mode with GUI: `npm run test:e2e`
+  - Headless mode without GUI: `npm run test:e2e -- --headless`
+
+📖 Read more about testing in [tests](./tests.md).
+
+### Linting
+
+- Lint all (recommended 💡): `npm run lint`
+- Markdown: `npm run lint:md`
+- Markdown consistency `npm run lint:md:consistency`
+- Markdown relative URLs: `npm run lint:md:relative-urls`
+- JavaScript/TypeScript: `npm run lint:eslint`
+- Yaml: `npm run lint:yaml`
+
+### Running
+
+- Run in local server: `npm run serve`
+  - 💡 Meant for local development with features such as hot-reloading.
+- Run using Docker:
+  1. Build: `docker build -t undergroundwires/privacy.sexy:latest .`
+  2. Run: `docker run -it -p 8080:80 --rm --name privacy.sexy undergroundwires/privacy.sexy:latest`
+
+### Building
+
+- Build web application: `npm run build`
+- Build desktop application: `npm run electron:build`
+- (Re)create icons (see [documentation](../img/README.md)): `npm run create-icons`
+
+## Recommended extensions
+
+You should use EditorConfig to follow project style.
+
+For Visual Studio Code, [`.vscode/extensions.json`](./../.vscode/extensions.json) includes list of recommended extensions.

 # Presentation layer
 
-- Consists of Vue.js components and other UI-related code.
+Presentation layer consists of UI-related code. It uses Vue.js as JavaScript framework and includes Vue.js components. It also includes [Electron](https://www.electronjs.org/) to provide functionality to desktop application.
-- Desktop application is created using [Electron](https://www.electronjs.org/).
+
-- Event driven as in components simply listens to events from the state and act accordingly.
+It's designed event-driven from bottom to top. It listens user events (from top) and state events (from bottom) to update state or the GUI.
