+# crycord
+
+Crycord is a modular Discord Client Mod written in Crystal.
+
+Uses [asar-cr](https://github.com/GeopJr/asar-cr).
+
+## Installation
+
+You can download the *statically* linked build from the releases page!
+
+## Building
+
+1. `shards install`
+2. `crystal build --release`
+
+*Note:* Static builds can only be built in AlpineLinux
+
+## Usage
+
+```
+$ ./crycord -h
+
+<== [Crycord] ==>
+    -v, --version                    Show version
+    -h, --help                       Show help
+    -gs, --groups                    Lists all available plugin groups
+    -p, --plugins                    Lists all available plugins
+    -c CSS_PATH, --css=CSS_PATH      Sets CSS location
+    -f CORE_ASAR_PATH, --force=CORE_ASAR_PATH
+                                     Forces an asar path
+    -g PLUGIN_GROUP, --group=PLUGIN_GROUP
+                                     Selects the plugin group(s) to install. Split multiple groups with commas(,).
+```
+
+```
+$ ./crycord -c ./Downloads/css.css
+
+Flatpak Detected:
+Make sure it has access to your CSS file
+Usually ~/Downloads is accessible
+Extracting core.asar...
+Installing enable_css...
+Installing enable_https...
+Packing core.asar...
+Done!
+Restart Discord to see the results!
+```
+
+## Benchmarks
+
+Crycord:
+```
+$time ./crycord -c ~/Downloads/css.css
+...
+
+real	0m2,942s
+user	0m2,932s
+sys	0m0,462s
+```
+
+BeautifulDiscord:
+```
+$ time python3 -m beautifuldiscord --css ~/Downloads/css.css
+...
+
+real	0m4,593s
+user	0m2,026s
+sys	0m2,381s

+
+## WARNING
+
+- Any Discord Client modification is against their T.O.S.
+- I am not responsible if your account gets terminated.
+- Using a client mod such as this (and all others), deactivates many electron security functions.
+- If a Discord Staff happens to stumble upon this, I don't use this tool on my account and it's made for educational purposes.
+
+## Goals
+
+As I also wrote the shard that manages the asar pack/extract (these 2 functions at least),
+my main goal is to achieve max speed and max compatibility. Using Crystal only tools like Path, File, Dir etc.
+is one way to reach it. However, since I don't have access to a Mac and Windows doesn't have proper support, some
+paths (Discord config) are made specifically for linux.
+
+## How is it different than BeautifulDiscord?
+
+First of all, it's written, well... in Crystal!
+
+That alone makes it a lot faster!
+
+Crycord also has a plugin(?) system!
+
+Lastly, it can patch the flatpak version.
+
+## TODO
+
+- Use a cross-platform way to find Discord's pid
+- Clean the module collector
+- GitHub action using docker in an attempt to build static builds automatically
+
+## Contributing
+
+1. Fork it (<https://github.com/your-github-user/crycord/fork>)
+2. Create your feature branch (`git checkout -b my-new-feature`)
+3. Commit your changes (`git commit -am 'Add some feature'`)
+4. Push to the branch (`git push origin my-new-feature`)
+5. Create a new Pull Request
