 # statement logic !!!
 
-things that are in here:
+things you can do with this:
 
-### general statement things
-
-#### [Logic/Statement/Parse.hs](Logic/Statement/Serialize.hs)
+### general things
 
 - parse string -> statement
-- serialize a statement -> plaintext, LaTeX, or L (the formal language)
-
-#### [Logic/Language/Impl/L.hs](Logic/Language/Impl/L.hs)
-
 - parse L (the formal language) string -> statement
+- serialize a statement to plaintext, LaTeX, L (the formal language)
 
 ### semantic things (statements have meaning I guess)
 
-#### [Logic/Statement/Eval.hs](Logic/Statement/Eval.hs)
-
-- assign truth values and evaluate statements
-- determine tautology, contradiction, or contingent
-
-#### [Logic/Statement/Serialize.hs](Logic/Statement/Serialize.hs)
-
-- generate a LaTeX truth table from a statement
-
-#### [Logic/Statements/Laws.hs](Logic/Statements/Laws.hs)
-
+- evaluate statements
+- from a statement generate a LaTeX truth table
 - match/replace patterns in statements (e.g. logical laws)
 - verify logical-law equivalence of statements (TODO)
-- find logical-law equivalence of statements with breadth-first search (slow)
+- find logical-law equivalence of statements with breadth-first search
 
 ### syntactic things (statements are strings of symbols)
 
-#### [Logic/Language.hs](Logic/Language.hs)
-
-- implement formal languages (symbols, axioms schemas, and inference rules)
-  with a clunky api, see also
+- implement formal languages (symbols, axioms schemas, and inference rules):
   <https://en.wikipedia.org/wiki/Post_canonical_system>
-
-### [Logic/Language/Derivation.hs](Logic/Language/Derivation.hs)
-
 - verify derivations in formal languages
 
 ### formal languages implemented
 
-- [the MIU system](Logic/Language/Impl/MIU.hs) (from "Gödel, Escher, Bach")
-- [L](Logic/Language/Impl/L.hs)
-
-### general things
-
-#### [Logic/Parse.hs](Logic/Parse.hs)
-
-- generic sequence parser
-
-#### [Logic/Graph.hs](Logic/Graph.hs)
-
-- generic breadth-first search
+- the MIU system (from "Gödel, Escher, Bach")
