+# 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
+First Build the jar, then cd into the `scripts` directory and run `./windows<bits>-bundler.sh` (or `./windows<bits>-bundler.ps1` if you are on windows), the resulting built zip package file will be `server/build/Tachidesk-vX.Y.Z-rxxx-win64.zip`.
+## Running in development mode
+First satisfy [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 opened 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.
