 ## Compiling
 
+The project is known to compile with:

+To install Iris, follow instructions [there][iris-coq].

 To compile the Coq scripts:

 ## Index of modules
 
+Important modules are highlighted.
+
  *  `Misc`: some basic things
  *  `Auth_nat`, `Auth_mnat`: simple lemmas about the authoritative resources on
     (ℕ, +) and (ℕ, max)
  *  `Reduction`: generic lemmas about reduction, safety, closedness, fresh
     locations… [should be renamed or split into several files]
- *  `Tactics`: tactics that help reducing concrete terms
- *  `Translation`: definition of the translation and syntactic lemmas about it
- *  `Simulation`: Lemmas about the operational semantics of the translation
- *  `TimeCredits`: implementation of time credits
- *  `TimeReceipts`: implementation of time receipts
- *  `Examples`: a (too) simple example illustrating the use of time credits
- *  `Thunks`: implementation of timed thunks using time credits
- *  `test`: an alternative proof of the main theorem of time credits, that does
-    not rely on the unsafe behaviour of `tick` [to be merged into `TimeCredits`]
+ *  `Tactics`: helper tactics to reduce concrete terms
+ *  __`Translation`: definition of the translation and syntactic lemmas about
+    it__
+ *  __`Simulation`: generic definition of `tick`; operational lemmas about the
+    translation with that `tick`__
+ *  __`TimeCredits`: interface, implementation, and proof of soundness for time
+    credits (plus a proof-mode tactic `wp_pay`)__
+ *  __`TimeCreditsAltProofs`: alternative proofs of the soundness theorem of
+    time credits, that does not rely on the unsafe behavior of `tick`__
+ *  __`TimeReceipts`: interface, implementation, and proof of soundness for time
+    receipts (both exclusive and persistent)__
+ *  `Examples`: a very simple example illustrating the use of time credits to
+    specify a program with lists
+ *  __`Thunks`: implementation of timed thunks using time credits__
