+# GCGM - Grasscutter Game Master Dashboard
+GCGM is the first [Grasscutter](https://github.com/Grasscutters/Grasscutter) plugin (Apart from Magix's test plugin) and it's goal is to implement a dashboard into the dispatch server so that game masters/server administrators can easily administor their server.
+
+## Currently Planned Features: 
+- [x] Loading basic web page
+- [ ] Nice looking CSS
+- [ ] Server performance stats
+- [ ] See players registered to dispatch server
+- [ ] See players currently online
+- [ ] Send mail to all players
+- [ ] Give players items
+- [ ] Summon enemies near players
+
+The features listed are to achieve an MVP for the first release.
+
+## 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 the web dashboard only displays the default react webpage. \
+**If you require support please ask on the [Grasscutter Discord](https://discord.gg/T5vZU6UyeG). However, support is not guarenteed.**
+
+## Setup 
+### Download Plugin Jar
+Coming soon!
+
+### Compile yourself
+1. Pull the latest code from github using ``git clone https://github.com/Grasscutters/gcgm-plugin`` in your terminal of choice.
+2. Navigate into the newly created ``gcgm-plugin`` folder and run ``gradlew build`` (cmd) **or** ``./gradlew build`` (Powershell, Linux & Mac).
+3. Assuming the build succeeded, in your file explorer navigate to the ``gc-plugin`` folder, you should have a ``gcgm-plugin.jar`` file, copy it.
+4. Navigate to your ``Grasscutter`` server, find the ``plugins`` folder and paste the ``gcgm-plugin.jar`` into it. 
+5. Start your server.
+6. Your server should then start and after a few seconds, you should be greated with these messages and the server will quit.
+```
+[WARN] The './plugins/gcgm/www' folder does not exist.
+[WARN] Please extract the contents of 'DefaultWebApp.zip' from within './plugins/gcgm' to './plugins/gcgm/www
+[WARN] Your server will now exit to allow this process to be completed
+```
+7.  Inside the ``plugins`` folder there now should be a new folder with the name of ``gcgm``, when you open the folder, there should be a ``.zip`` file called ``DefaultWebApp.zip``. Extract the contents of this zip into a folder called ``www``.
+
+Your final plugins folder's directory structure should look similar to this
+```
+plugins
+│   gcgm-plugin.jar
+│   ...
+└───gcgm
+    │   DefaultWebApp.zip
+    │
+    └───www
+        │   asset-manifest.json
+        │   favicon.ico
+        │   index.html
+        │   logo192.png
+        │   logo512.png
+        │   manifest.json
+        │   robot.txt
+        └───static
+            └───css
+            │   ...
+            └───js
+            │   ...
+            └───media
+            │   ...
+```

+#   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

+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+
+The page will reload when you make changes.\
+You may also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
+
+If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
+
+You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
