+# MusFuse
+
+[![Build Status](https://travis-ci.org/joemccann/dillinger.svg?branch=master)](https://travis-ci.org/joemccann/dillinger)
+
+MusFuse is a FUSE filesystem over HTTP for music. It is using [playongo](https://github.com/nixargh/playongo) media library. It's completely written in Rust stable.
+
+
+# Features
+  - Using self hosted media library.
+  - Security relies on HTTPS.
+  - Any player can be used. (tested on [Cmus](https://github.com/cmus/cmus))
+  - Using cache.
+  - Leverages Rust correctness.
+
+# How to use
+
+```sh
+# Compile
+$ cargo build --release
+# And run
+$ ./target/release/musfuse <mountpoint> <server>
+```
