+Nimui is a [Nim](https://nim-lang.org/) wrapper for the [libui](https://github.com/andlabs/libui) library.
+
+Nimui is distributed as a [Nimble](https://github.com/nim-lang/nimble) package and depends on [nimgen](https://github.com/genotrance/nimgen) and [c2nim](https://github.com/nim-lang/c2nim/) to generate the wrappers. The libui source code is downloaded using Git so having ```git``` in the path is required.
+
+__Installation__
+
+Nimui is currently a work in progress. It can be installed via [Nimble](https://github.com/nim-lang/nimble):
+
+```
+> nimble install nimgen
+
+> git clone https://github.com/genotrance/nimui
+> cd nimui
+> nimble install -y
+```
+
+This will download, wrap and install nimui in the standard Nimble package location, typically ~/.nimble. Once installed, it can be imported into any Nim program.
+
+__Usage__
+
+TBD
+
+```nim
+import nimui/ui
+
+var opts: UiInitOptions
+if uiInit(addr opts) != nil:
+  quit(1)
+```
+
+__Credits__
+
+Nimui wraps the [libui](https://github.com/andlabs/libui) library and all its licensing terms apply to the usage of this package.
+
+Credits go out to [c2nim](https://github.com/nim-lang/c2nim/) as well without which this package would be greatly limited in its abilities.
+
+__Feedback__
+
+Nimui is a work in progress and any feedback or suggestions are welcome. It is hosted on [GitHub](https://github.com/genotrance/nimui) with an MIT license so issues, forks and PRs are most appreciated.
