 ## 📋 Roadmap
 - [x] Decrypt .cia
   - [x] Games
   - [x] Patch and DLCs
 - [x] Decrypt .3ds
-- [ ] Rust 'decrypt.py' rewrite
+- [ ] Rust/C++ 'decrypt.py' rewrite
 
 ## ⚡️ Build from source
 You’ll need the [Crystal compiler](https://crystal-lang.org/install/)
 
-`crystal build cia-unix.cr --release`
+```
+crystal build cia-unix.cr --release --no-debug
+```
 
 Dependencies can be compiled with [makerom](https://github.com/3DSGuy/Project_CTR/tree/master/makerom) and [ctrtool](https://github.com/3DSGuy/Project_CTR/tree/master/ctrtool) make files
 
 ## Contributors
