-# BurritOS Test programs
-This folder contains small C programs pertaining to the assessment of the correctness of BurritOS' behavior.
-
-## Folder Structure
- - **riscv_instructions**: contains small programs for testing simulator instruction coverage.
-
-## How to build
-### In the Makefile.config file
-Set the variables to the correct paths for the [RISCV Newlib compilation toolchain](https://github.com/riscv-collab/riscv-gnu-toolchain). Simply changing the `RISCV_PREFIX` variable should do the trick. **Do not forget to add a trailing slash**.
