@@ -7,6 +7,9 @@ To build:
 - With GMP: Run `make -j1` (any more than `-j1` doesn't really do anything, there's four things to do and they can't be put out of order).
 - Without GMP: Run `make gmpless -j1` (see above parenthetical statement).
 
+You can get releases at [here](https://git.sdf.org/ilikecats/collatz/releases), but only GMP releases (except for 1.0), and only for GNU/Linux (except for 1.0).
+You have to build without GMP if you don't want to/can't use GMP.

 Algorithm:
 - Start with number.
 - If number is even, divide by two.
