-# GCAuth_OAuth
-The in-game login system for Grasscutter is based on oauth and GCAuth.
+# GCAuth OAuth
+
+The in-game login system for [Grasscutter](https://github.com/Grasscutters/Grasscutter) is based on oauth and [GCAuth](https://github.com/exzork/GCAuth).
+
+## Current Features:
+
+- [x] Use twitter oauth to login
+- [ ] Error page
+
+## Important Notes:
+
+This plugin is made to run on the current [Development](https://github.com/Grasscutters/Grasscutter/tree/development) branch of Grasscutter. \
+
+This plugin is in very early development and only have the backend now. Frontend is extermely hardcore.
+
+## Setup
+
+### Download Plugin Jar
+
+See releases.
+
+### Compile yourself
+
+1. Pull the latest code from github using ``git clone https://github.com/Xtao-Team/GCAuth-OAuth`` in your terminal of choice.
+2. Locate your grasscutter server and copy the ``grasscutter`` server jar into the newly created ``GCAuth-OAuth/lib`` folder
+3. Navigate back into the project root folder called ``GCAuth-OAuth`` folder and run ``gradlew build`` (cmd) **or** ``./gradlew build`` (Powershell, Linux & Mac).
+4. Assuming the build succeeded, in your file explorer navigate to the ``GCAuth-OAuth`` folder, you should have a ``gcauth_oauth.jar`` file, copy it.
+5. Navigate to your ``Grasscutter`` server, find the ``plugins`` folder and paste the ``gcauth_oauth.jar`` into it.
+6. Start your server.
+
+...Jump to next section...
+
+### Usage
+
+7. Put the all the [frontend](#Frontend) files into the folder `GRASSCUTTER_RESOURCE/plugins/GCAuth/OAuth`. Note that your must have `login.html` for now. You are free to put any other dynamiclly loaded file(e.g. `.js`, `.css`) in that folder. Check the last section for current available frontend.
+
+8. Put the ``gcauth.jar`` file into the ``plugins`` folder of your grasscutter server. [GCAuth](https://github.com/exzork/GCAuth)
+
+9. Log in to your server and you should be able to log in with Twitter account. (make sure `webapi-os.account.hoyoverse.com` is in your proxy list)
+
+Your final plugins' folder's directory structure should look similar to this
+```
+plugins
+│   gcauth.jar
+│   gcauth_oauth.jar
+│   ...
+└───GCAuth
+    │   config.json
+    └───OAuth
+        │   login.html
+        │   ...
+```

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
