 # borg-web
-web server for borg-manager
+Summarises [borg](https://borgbackup.readthedocs.io/en/stable/#what-is-borgbackup) backups using output from '[borg create](https://borgbackup.readthedocs.io/en/stable/usage/create.html#description)'.
+Supersedes my previous project [borg-manager](https://github.com/georgelacey/borg-manager). 
+
+## Summary
+Borg web consists of two components, a client 'borg-client' and [Django](https://www.djangoproject.com/) web server 'borgweb',
+json output from borg create is piped to the client, which sends it to the web server.
+If no json is output, an error is assumed, which is then logged.
+
+## Features:
+* Parses json output from 'borg create --json'
+* Stores repo and archive information in database
+* Logs errors
+* Hosts repo summary page
+
+## Notes
+This is a project used by me to keep track of borg backups on a locally hosted server, for this reason it is not suitable for use by you unless you know what you're doing
