+## What is "Skillbird" ?
+Skillbird is a framework around the python-Trueskill library, which can parse files of versus games to calculate a rating, matchmaking suggestions for future games or create predictions for the outcome of a game with certain team compositions.
+
+## Adaption for your own Data
+### Data Requirements
+To work correctly you data must have the following fields:
+- unique player id or name
+- player(s) in winning and losing team
+
+You may also have the following informations:
+- data/time of the game (you cannot use the cached-rebuild feature without this)
+- time players spent playing compared to the full length of the game
+- teamchanges of 
+- different maps
+
+### Data Input
+If you use the official source-plugin and it's output, you don't have to do anything. Alternatively can write your own parser (see the skillbird-examples project), or you can conform to the Source-format which supports the following log-lines. None of the input values may contain any of the separators used (**pipe** and **comma**) or the line identifier (**0x42**).
+
+    # reset state
+    0x42,plugin_unloaded
+    
+    # declare the current map
+    0x42,mapname,MAP_NAME
+    
+    # start a round
+    0x42,round_start_active,PLAYER_ID|PLAYER_NAME|TEAMI_D,PLAYER_ID....
+    
+    # record team changes (ct) or disconnects (dc) and the team composition after it
+    # the backend will handle those accordingly
+    0x42,ct,PLAYER_ID|PLAYER_NAME|TEAMI_D,PLAYER_ID....
+    0x42,dc,PLAYER_ID|PLAYER_NAME|TEAMI_D,PLAYER_ID....
+
+    # declare the team-composition at the end of the round
+    # the backend will use this information for sanity checks
+    0x42,round_end_active,PLAYER_ID|PLAYER_NAME|TEAMI_D,PLAYER_ID....
+    
+    # name the winning team  and end the round
+    0x42,winner,WINNING_TEAM_ID
+
+## Usage
+    usage: startInsurgency.py [-h] [--parse-only] [--start-at-end] [--no-follow]
+                              [--one-thread] [--cache-file CACHEFILE]
+                              FILE [FILE ...]
+    
+    positional arguments:
+      FILE                  one or more logfiles to parse
+    
+    optional arguments:
+      -h, --help            show this help message and exit
+      --parse-only, -po     only parse, do not listen for queries
+      --start-at-end, -se   start at the end of each file (overwrites no-follow)
+      --no-follow, -nf      wait for changes on the files (does not imply start-
+                            at-end)
+      --one-thread          run everything in main thread (implies no-follow)
+      --cache-file CACHEFILE
+                            A cache file which makes restarting the system fast
+
+## Query Options
+Skillbird has a TCP-Query interface which supports the following queries. The separator for player-IDs is always a**comma** and the separator for for teams is always a **pipe** as before, those special characters may not be contained in any of the actual input values.
+
