 ## Files
 
-Simexec is a single C file (`simexec.c`) that builds to a single executable,
-which should be named `simexec` and placed in a user-accessible binaries
-directory. A `Makefile` is provided as courtesy but isn't really necessary.
-
-The `src/simexec` directory can be moved to a system sources directory if you
-wish to keep the source on hand; it doesn't reference anything else in the
+- `src/simexec`
+	- Can be moved to a system sources directory if it's desirable to keep
+		system sources on hand. Doesn't reference anything else in the
 		repository.
 
-The included manual page, `simexec.1` can be placed in the appropriate manual
-pages directory. If it displays weirdly feel free to e-mail me and I'll attempt
-to fix it.
+- `simexec.1`
+	- Included manual page for `simexec`. Can be placed in the appropriate
+		manual pages directory. If it displays weirdly and your fix is
+		portable, mail me and I'll probably bring it upstream.

+## Dependencies
+
+- `<sysexits.h>`
+	- Ignored if `EX_USAGE` is already defined.
+
+- C standard library
 
 ## Compilation
 
-On systems that provide `<sysexits.h>`, the following is all that's needed:
-
 ```
 cc -o simexec simexec.c
 ```
 
-If you're not sure whether your system provides `<sysexits.h>`, try it and see.
-If it doesn't work, compile `simexec.c` with the following:
+Or without `<sysexits.h>`:
 
 ```
 cc -DEX_USAGE=1 -o simexec simexec.c
 ```
 
-Other than `<sysexits.h>` simexec(1) only relies on headers found in the C
-standard library. Outside of POSIX environments `simexec.c` probably won't work
-but it wouldn't be of much use anyway.
