 ## Credits
 The server uses the following libraries:
 - [cpp-httplib](https://github.com/yhirose/cpp-httplib) for the web server 
 - [Maddy](https://github.com/progsource/maddy) for the Markdown processor
 - [Bcrypt.cpp](https://github.com/hilch/Bcrypt.cpp) for password hashing/salting
 - [JSON for Modern C++](https://github.com/nlohmann/json) for JSON processing
 - [bin2cpp](https://github.com/end2endzone/bin2cpp) for packing site files into the binary
 The following people have contributed to the project:
 - [SpookyDervish](https://chookspace.com/SpookyDervish) for client navbar and notification sound
 - [reallynniroprobably](https://chookspace.com/reallynniroprobably) for error message
