 This project has minimal dependency on Xcode-only features (e.g. InterfaceBuilder, Playgrounds). You can build it by doing:

 * `scripts/codesign/setup_local.sh` to generate a local self-signed certificate, to avoid having to re-check the `System Preferences > Security & Privacy` permissions on every build
 * Either open `alt-tab-macos.xcworkspace` with XCode, or use the cli: `xcodebuild -workspace alt-tab-macos.xcworkspace -scheme Debug` to build the .app with the `Debug` build configuration

+## Mac development

 Mac development ecosystem is pretty terrible in general. They keep piling on the tech stacks on top of each other, so you have C APIs, ObjC APIs, Swift APIs, Interface builder, Playgrounds, Swift UI, Mac Catalyst. All these are bridging with each other with a bunch of macros, SDKs glue, compiler flags, compatibility mode, XCode legacy build system, etc. For alt-tab, we are on Swift 5.0. Note that swift just recently started being stable, but overall any change of version breaks a lot of stuff. Swift itself is the mainstream language with the worst governance I’ve seen in modern times.

 OS APIs are quite limited for the kind of low-level, system-wide app AltTab is. This means often we just don’t have an API to do something. For instance, there is no API to ask the OS “how many Spaces does the user have?” or “Can you focus the window on Space 2?”. There are however, retro-engineered private APIs which you can call. These are not documented at all, not guaranteed to be there in future macOS releases, and prevent us from releasing AltTab on the Mac AppStore. We have tried our best to [document the ones we are using](https://github.com/lwouis/alt-tab-macos/blob/master/src/api-wrappers/private-apis/README.md), as well as [the ones we investigated](https://github.com/lwouis/alt-tab-macos/blob/master/src/experimentations/PrivateApis.swift) in the past.

+## Can it show, or hide, this window?
+
+It's sometimes hard to say that some dialog, HUD, UI element, is a window or not. Not everyone will agree that a particular window is a window. AltTab does its best to decide what a window is, and show it to the user.
+
+Some apps are not native macOS apps, or poorly programmed. Such apps will use "windows" to code things like menus, and play tricks like hidding a window instead of closing it. Notorious examples: Electron apps (e.g. Slack, Discord, etc) and apps using cross-platform SDKs (e.g. Adobe apps, Steam, IntelliJ, etc).
+
+If a window is showing, and you think it shouldn't, please contact the app maker so they can fix their product.
+
+## Can it show individual browser tabs?
+
+Browser windows are not standard windows or tabs. They are custom UI painted by each browser, in their own unique way. There is no macOS API to screenshot a browser tab. Some browser may not even render a tab that's not active, so there are no pixels to screenshot. 
+
+Browser may offer custom integration to know about tabs, screenshot, active them. However, each browser is unique, and it would require to write these integrations for each one, as well as to maintain them. Browsers evolve fast, so maintaining multiple fast-changing integrations is not attainable.
+
+## Can we add window-management features?
+
+AltTab is not intended to be a window manager. It will not add features such as: resizing windows, organizing them into tiles, Dock enhancements.
+
+[Other apps](http://localhost:4000/#alternatives) offer such experiences.
+
+AltTab aims at being the best at the Windows-style alt+tab experience.
+
+## Can it be on the App Store?
+
+AltTab uses **many** private APIs. This prevents us from publishing on the App Store. It's a shame. Many more casual users would benefit from it. However, without these private APIs, the user experience would be crippled. We use private APIs for refined details, but also for basic functionality.  
+
+## Where are settings stored?
+
+The app uses the standard macOS API to store settings. You can interact with them from the Terminal, using the `defaults` command:
+* List current settings: `defaults read com.lwouis.alt-tab-macos.plist`
+* Update a setting: `defaults write com.lwouis.alt-tab-macos.plist AppleAccentColor -int 4`
+* Export settings to a file: `defaults export com.lwouis.alt-tab-macos.plist /tmp/my-export.plist`
+
+## Can I share an idea or report a bug?
+
+Please open an issue on [GitHub](https://github.com/lwouis/alt-tab-macos/issues)

-## Privacy and respecting the user
+## Privacy

-* AltTab doesn’t upload or download any data without the user explicitly asking for it (e.g. asking to update the app, sending a crash report, etc)
-* AltTab uses as few resources as possible: CPU, memory, disk, etc. The app footprint is small (e.g. small disk size, minimal CPU use in the background, etc)
+AltTab doesn’t communicate to any server for so-called telemetry. AltTab will only use the network if it's absolutely required (e.g. checking for updates).
+
+## Performance
+
+AltTab has been designed to take as few resources as possible on the user computer. The app itself is kept as small as possible. CPU usage is kept to a minimum, especially while in the background. The goal is to respect the user and try to have no negative impact on their experience.
