+Servefile
+=========
+
+Serve files from shell via a small HTTP server. The server redirects all HTTP
+requests to the file, so only IP and port must be given to another user to
+access the file. Its main purpose is to quickly send a file to users in your
+local network, independent of their current setup (OS/software). Besides that
+it also supports uploads, SSL, HTTP basic auth and directory listings.
+
+Features:
+ * serve single file
+ * serve a directory with directory index
+ * file upload via webinterface
+ * HTTPS with on the fly generated self signed SSL certificates
+ * HTTP basic authentication
+ * serving files/directories as on request generated tar files
+
+Install
+-------
+
+Via pip
+```shell
+pip install servefile
+```
+After installation either execute `servefile --help` or `python -m servefile --help`
+
+Standalone:
+If you don't have pip available just copy `servefile/servefile.py` onto the target machine, make it executable and you are ready to go.
+```shell
+$ wget https://raw.githubusercontent.com/sebageek/servefile/master/servefile/servefile.py -O servefile
+$ chmod +x servefile
+$ ./servefile --help
+```
