+# nikke-server
+Private/local server for Nikke.
+
+## Usage
+First, build and run nksrv project.
+
+After that, add the following to your C:\Windows\System32\hosts or /etc/hosts file to use the local server:
+
+```
+127.0.0.1 cloud.nikke-kr.com
+127.0.0.1 global-lobby.nikke-kr.com
+127.0.0.1 aws-na-dr.intlgame.com
+127.0.0.1 sg-vas.intlgame.com
+127.0.0.1 aws-na.intlgame.com
+127.0.0.1 common-web.intlgame.com
+127.0.0.1 li-sg.intlgame.com
+127.0.0.1 data-aws-na.intlgame.com
+255.255.221.21 sentry.io
+```
+
+As Nikke encrypts packet data, you also need to replace C:\NIKKE\NIKKE\game\nikke_Data\Plugins\x86_64\sodium.dll. A patched version of this file can be obtained by contacting MishaProductions on Discord.
+
+After doing the following steps, you can register an account in the launcher (enter anything into email verification code section), and play like normal.
+
+## Progress
+Currently, stage data is not saved, only story completion is saved. There are also no rewards currently because those are given server side.
+
+
+## Contributing
+You can help by providing information about what rewards are given when a stage is completed, etc. 
+
+Server code structure:
+
+nksrv/LobbyServer: Handles save data.
+nksrv/IntlServer: Provides Launcher APIs and authentication
+nksrv/Protos: Google protobuf definition files
+DataFixupUtil: Utility to parse packets from server/client
