+# gavin
+
+Simple utility to serve password protected WebDAV.
+
+## Example usage
+
+`gavin` was built as a simple WebDAV server specifically to run
+[organice](https://github.com/200ok-ch/organice). Here is an example showing how
+to host organice via WebDAV.
+
+| Flag      | Value               | Description                                                                             |
+|-----------|---------------------|-----------------------------------------------------------------------------------------|
+| `-davdir` | /tmp/org            | The directory we have our .org files in.                                                |
+| `-htpass` | /tmp/.htpasswd      | Standard `htpasswd` file generated with `htpasswd`. Currently only bcrypt is supported. |
+| `-static` | /tmp/organice/build | The directory that contains the built organice files.                                   |
+
+```
+gavin -davdir /tmp/org -htpass /tmp/.htpasswd -static /tmp/organice/build/
+```
+
+Now you can open your browser to
+[http://localhost:8080/](http://localhost:8080/), sign in using the credentials
+in the `.htpasswd` file, and org away!
