+# nim-win-registry
+A Windows Registry wrapper for Nim. Nim procs for the raw
+[C function definitions](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724868(v=vs.85).aspx) are defined
+in `registrydef.nim`. `registry.nim` provides a more high-level API for interacting with the registry, but doesn't
+support specialized cases like interacting with the security settings. It should cover most cases for storing
+application settings, though. The higher-level wrapper is modeled after the
+[C#-API](https://msdn.microsoft.com/en-us/library/microsoft.win32.registrykey(v=vs.110).aspx) for the registry. It
+also checks for error codes automatically and throws exceptions if an error occured.
+
+Sample Usage:
+
+```nim
+let key = HKEY_CURRENT_USER.openSubKey("SOFTWARE\\YourCompany\\YourSoftware", true)
+echo key.getValue("version", "1.0.0")
+key.setValue("version", "1.1.0")
+key.close()
+```
+
+If you opened a key, do not forget to close it if you don't need it anymore.
