+# Contributing
+## Where should I start?
+Checkout [This Kanban Board](https://github.com/Suwayomi/Tachidesk/projects/1) to see the rough development roadmap.
+
+**Note to potential contributors:** Notify the developers on Suwayomi discord (#programming channel) or open a WIP pull request before starting if you decide to take on working on anything from/not from the roadmap in order to avoid parallel efforts on the same issue/feature.
+
+## How does Tachidesk work?
+This project has two components: 
+1. **server:** contains the implementation of [tachiyomi's extensions library](https://github.com/tachiyomiorg/extensions-lib) and uses an Android compatibility library to run apk extensions. All this concludes to serving a REST API to `webUI`.
+2. **webUI:** A react SPA(`create-react-app`) project that works with the server to do the presentation.
+
+## Why a web app?
+This structure is chosen to
+- Achieve the maximum multi-platform-ness
+- Gives the ability to acces Tachidesk from a remote web browser e.g. your phone, tablet or smart TV
+- Eaise development of alternative user intefaces for Tachidesk
+
+## User Interfaces for Tachidesk server
+Currently there are three known interfaces for Tachidesk:
+1. [webUI](https://github.com/Suwayomi/Tachidesk/tree/master/webUI/react): The react SPA that Tachidesk is traditionally shipped with.
+2. [TachideskJUI](https://github.com/Suwayomi/TachideskJUI): A Jetbrains Compose Native app, re-uses components made for the upcoming Tachiyomi 1.x
+3. [Equinox](https://github.com/Suwayomi/Equinox): A web user interface made with Vue.js, in super early stages of development.
+
+## Building from source
+### Prerequisites
+You need these software packages installed in order to build the project
+### Server
+- Java Development Kit and Java Runtime Environment version 8 or newer(both Oracle JDK and OpenJDK works)
+- Android stubs jar
+    - Manual download: Download [android.jar](https://raw.githubusercontent.com/Suwayomi/Tachidesk/android-jar/android.jar) and put it under `AndroidCompat/lib`.
+    -  Automated download: Run `AndroidCompat/getAndroid.sh`(MacOS/Linux) or `AndroidCompat/getAndroid.ps1`(Windows) from project's root directory to download and rebuild the jar file from Google's repository.
+### webUI
+- Nodejs LTS or latest
+- Yarn
+- Git
+### building the full-blown jar
+Run `./gradlew :webUI:copyBuild server:shadowJar`, the resulting built jar file will be `server/build/Tachidesk-vX.Y.Z-rxxx.jar`.
+### building without `webUI` bundled(server only)
+Delete the `server/src/main/resources/react` directory if exists from previous runs, then run `./gradlew server:shadowJar`, the resulting built jar file will be `server/build/Tachidesk-vX.Y.Z-rxxx.jar`.
+### building the Windows package
+Run `./gradlew :server:windowsPackage` to build a server only bundle and `./gradlew :webUI:copyBuild :server:windowsPackage` to get a full bundle , the resulting built zip package file will be `server/build/Tachidesk-vX.Y.Z-rxxx-win32.zip`.
+## Running in development mode
+First satistify [the prerequisites](#prerequisites)
+### server
+run `./gradlew :server:run --stacktrace` to run the server
+### webUI
+How to do it is described in `webUI/react/README.md` but for short,
+ first cd into `webUI/react` then run `yarn` to install the node modules(do this only once)
+ then `yarn start` to start the development server, if a new browser window doesn't get opned automatically,
+ then open `http://127.0.0.1:3000` in a modern browser. This is a `create-react-app` project
+ and supports HMR and all the other goodies you'll need.

-You should have The Java Runtime Environment(JRE) 8 or newer and a modern browser installed. Also an internet connection is required as almost everything this app does is downloading stuff. 
+You should have The Java Runtime Environment(JRE) 8 or newer and a modern browser installed(Google is your friend for seeking assitance). Also an internet connection is required as almost everything this app does is downloading stuff. 
 
-Download the latest jar release from [the releases section](https://github.com/Suwayomi/Tachidesk/releases).
+Download the latest "Stable" jar release from [the releases section](https://github.com/Suwayomi/Tachidesk/releases) or a preview jar build from [the preview branch](https://github.com/Suwayomi/Tachidesk/tree/preview).
 
-Double click on the jar file or run `java -jar Tachidesk-vX.Y.Z-rxxx.jar` from a Terminal/Command Prompt window to run the app which will open a new browser window automatically. Also the System Tray Icon is your friend if you need to open the browser window again or close Tachidesk.

 ### Windows
 Download the latest win32 release from [the releases section](https://github.com/Suwayomi/Tachidesk/releases).
 
-The Windows specific build has java bundled inside, so you don't have to install java to use it. Unzip `Tachidesk-vX.Y.Z-rxxx-win32.zip` and run `server.exe`. The rest works like the previous section.

 ### Arch Linux
 You can install Tachidesk from the AUR
 ```
 yay -S tachidesk
 ```
+Or the latest preview version
+```
+yay -S tachidesk-preview

 ### Docker
 Check [arbuilder's repo](https://github.com/arbuilder/Tachidesk-docker) out for more details and the dockerfile.
 
-## General troubleshooting
-If the app breaks try deleting the directory below and re-running the app (**This will delete all your data!**) and if the problem persists open an issue. 
+### Using Tachidesk Remotely
+You can run Tachidesk on your computer or a server and connect to it remotely through the web interface with a web browser on any device including a mobile or tablet or even your smart TV!, this method of using Tachidesk is only recommended if you are a power user and know what you are doing.

-## How does it work?
-This project has two components: 
-1. **server:** contains the implementation of [tachiyomi's extensions library](https://github.com/tachiyomiorg/extensions-lib) and uses an Android compatibility library to run apk extensions. All this concludes to serving a REST API to `webUI`.
-2. **webUI:** A react SPA project that works with the server to do the presentation.
-
-## Building from source
-### Prerequisite: Get Android stubs jar
-#### Manual download
-Download [android.jar](https://raw.githubusercontent.com/Suwayomi/Tachidesk/android-jar/android.jar) and put it under `AndroidCompat/lib`.
-#### Automated download(needs `bash`, `curl`, `base64`, `zip` to work)
-Run `AndroidCompat/getAndroid.sh`(MacOS/Linux) or `AndroidCompat/getAndroid.ps1`(Windows) from project's root directory to download and rebuild the jar file from Google's repository.
-### Prerequisite: Software dependencies
-You need this software packages installed in order to build this project:
-- Java Development Kit and Java Runtime Environment version 8 or newer(both Oracle JDK and OpenJDK works)
-- Nodejs LTS or latest
-- Yarn
-### building the full-blown jar
-Run `./gradlew server:shadowJar`, the resulting built jar file will be `server/build/Tachidesk-vX.Y.Z-rxxx.jar`.
-### building without `webUI` bundled
-Delete the `server/src/main/resources/react` directory if exists from previous runs, then run `./gradlew server:shadowJar -x :webUI:copyBuild`, the resulting built jar file will be `server/build/Tachidesk-vX.Y.Z-rxxx.jar`.
-### building the Windows package
-Run `./gradlew windowsPackage`, the resulting built zip package file will be `server/build/Tachidesk-vX.Y.Z-rxxx-win32.zip`.
-## Running for development purposes
-### `server` module
-Follow [Get Android stubs jar](#prerequisite-get-android-stubs-jar) then run `./gradlew :server:run -x :webUI:copyBuild --stacktrace` to run the server
-### `webUI` module
-How to do it is described in `webUI/react/README.md` but for short,
- first cd into `webUI/react` then run `yarn` to install the node modules(do this only once)
- then `yarn start` to start the client if a new browser window doesn't start automatically,
- then open `http://127.0.0.1:3000` in a modern browser. This is a `create-react-app` project
- and supports HMR and all the other goodies you'll need.
