+# VSSM (VintageStory Server Manager)
+*A server manager for VintageStory*
+
+## IMPORTANT INFORMATION
+This project is currently in development, and thus everything is subject to change
+
+## About
+VSSM allows you to create and manage multiple VS servers 
+
+## Installation and Usage
+There are no binaries just yet, so you have to download the source files.
+
+Setup is easy from source, all you need is:
+- Linux
+- Go
+- .NET 10 Runtime
+
+**If you are using NixOS, a flake.nix is provided, just run `nix develop` for a full development enviroment**
+
+- Once you have the source code downloaded or cloned, you can run `go build` to generate an executable.
+- Run `./vssm daemon` to start the daemon - *(For now, theres no background service created by default, but you can run it in the background with `vssm daemon &` and kill the process with `pkill vssm`)*
+- Run `./vssm` with no arguments to show usage
+
+## Configuration
+**For now, the configuration file is stored in `~/.config/vssm/config.json`, but this will be configurable later.**
+
+
+
+## Roadmap
+
+- [-] Configuration
+    - [x] Application data path
+    - [x] Declarative Servers
+
+- [-] Server management
+    - [x] Create servers
+    - [x] Start/Stop servers
+    - [x] Multiple servers support
+    - [x] List servers and their status
+    - [ ] Delete servers
+    - [ ] Automated server backups
+
+- [ ] Binary releases
+
+- [-] Other
+    - [-] First class NixOS support
+        - [x] Patch downloaded server binaries for NixOS
+        - [ ] Official nix package or flake
+            - [ ] All configuration options
