+# Levitating
+
+_A continuous integration system built in Fortran_
+
+## About
+
+Levitating is an overly simple continuous integration system designed entirely in Fortran to, basically, replace Python's buildbot package (circa version 0.8).  The system is comprised of a _captain_, which acts as the control server, and a collection of _players_, each of which can be assigned _jobs_ to perform.  Build results are generally captured and returned to the _captain_ after a task is complete.
+
+The system is drastically simpler than the system it aims to replace.  The _captain_ has no knowledge of the details of jobs themselves.  The _players_ will report results from each _task_ in a _job_ back to the _captain_.  The _captain_ does store these results and display them when requested, but the tasks are only referred to numerically.
+
+## Requirements
+
+To build Levitating, you'll need:
+
+* GNU Fortran or another compiler that supports a handful of extensions used
+* libssl
+* json-fortran (version 7 series, untested with 8)
+
+## Instructions
+
+_Instructions_ are the list of _tasks_ that a _player_ needs to perform to complete a _job_.  The instructions are entirely written in JSON, which the _players_ then interpret.  Currently, 5 types of actions are supported:
+
+ * __shell__ - Execute a shell command on the host operating system's default shell
+ * __git__ - Either clone or pull, whichever is appropriate, from a git repo
+ * __download__ - Download a particular file from the _captain_
+ * __upload__ - Upload a file or files (globbing supported) to the _captain_
+ * __delete_tree__ - Delete a directory tree
+ 
+The above steps encompass what I needed to replace in buildbot personally.  If someone has a suggestion, write in!
+
+It should be noted that _players_ have absolutely no restrictions on functions like __download__ or __delete_tree__, and they will happily try to download system files or delete a root directory.
+ 
+## Protocol
+
+The _player_ processes will communicate with the _captain_ via the [Gemini protocol](https://gemini.circumlunar.space/), a quasi-standard that is meant as a simpler alternative to HTTP.  The _players_ will upload files to the server via the [Titan protocol](https://communitywiki.org/wiki/Titan), a system for uploading files meant to pair with the Gemini protocol.
+
+Currently, the only way to access the portal for starting _jobs_, adding _players_, or viewing results is also via the Gemini protocol.  You'll need to keep port 1965 open for the _captain_, which must be run via xinetd or inetd.
+
+A CGI gateway (that's not a typo) for a compatible HTTP server is planned but non-existent.
+
+## Security
+
+The current configuration has literally no security features.  Anyone who can connect to the _captain's_ interface can start jobs, download releases (the products of what the _players_ build, ostensibly), or manage _players_.  Additionally, _players_ are also not authenticated, so any process claiming to be an approved _player_ can just proceed with downloading/uploading files.
+
+The plan is to change this complete lack of authentication at some point.  It's probably not a great idea to leave an instance of Levitating up in a public-facing manner.
