 This matrix math library is focused on embedded development and avoids any heap memory allocation unless you explicitly ask for it.
 It uses templates to pre-allocate matrices on the stack.
 
-There are still several operations that are works in progress such as:
-- Add a function to calculate eigenvalues/vectors
-- Add a function to compute RREF
-- Add a function for SVD decomposition
-- Add a function for LQ decomposition
+# Building
+1. Initialize the repositiory with the command:
+```bash
+cmake -S . -B build -G Ninja
+```
+
+2. Go into the build folder and run `ninja`
+3. That's it. You can test out the build by running `./unit-tests/matrix-tests`
