-A single binary for both server and client of [tus resumable upload protocol](https://tus.io). 
+TUS **C**ommand line (tusc) is a small static binary for both server and client of [tus resumable upload protocol](https://tus.io). 
 
-This is a wrapper of [tusd](https://github.com/tus/tusd) with nginx-like file listing page (or index page) is added. 
-Features like S3, GCS, Prometheus, Hooks are removed from tusd, in favor of smaller binary size (< 5 MB after upx-ed rather than > 30MB raw). 
-This is a command line implementation this library [go-tusd](https://github.com/eventials/go-tus).
+Personally, I need tusc for uploading files in a CI process and a simple UI for downloading (like nginx autoindex). 
+The chucked and resumable feature make it possible to bypass some payload size limitation imposed by proxy.
+Also, small size of binary make it convenient to be included in docker image.
