 # tetanus_shares
 sharp sharesish but in rust!
 
-I've just started on this, so it doesn't quite work yet, but I think I'm close.
+# Usage:
+tetanus_shares -o C:\path\to\save -t threadcount
+
+If no arugments are givin it proceedes with the defaults of no save file, and 10 threads.
+
+# Building
+`git clone https://github.com/Pyro57000/tetanus_shares.git`
+
+`cd tetanus_shares`
+
+`cargo build --target x86_64-pc-windows-gnu --release`
+
+Then your exe will be in the target/x86_64-pc-windows-gnu/release directory!
+
+or you can just download the exe from the releases here.
