+Requirements
+---------------------
+- Python3
+- binary_c version 2.1+
+- requirements.txt (no?)
 
 Environment variables
 ---------------------
-
 Before compilation you should set the following environment variables:
 
-required: `BINARY_C` should point to the root directory of your binary_c installation
-
-recommended: `LD_LIBRARY_PATH` should include $BINARY_C/src and whatever directories are required to run binary_c (e.g. locations of libgsl, libmemoize, librinterpolate, etc.)
-
-recommended: `LIBRARY_PATH` should include whatever directories are required to build binary_c (e.g. locations of libgsl, libmemoize, librinterpolate, etc.)

 Build instructions
 ---------------------
-
-To build the module, make sure you have built binary_c (with "make" in the binar_c root directory), its shared library (with "make libbinary_c.so" in the binary_c root directory), and set environment variables as described above, then run:

+To build the module, make sure you have built binary_c (with `make` in the binary_c root directory), its shared library (with `make libbinary_c.so` in the binary_c root directory), and set environment variables as described above, then run the following code in t:
 ```
  make clean
  make
 ```
-
 Then to test the Python module:
 
 ```
  python3 ./python_API_test.py
 ```
-
 You will require whatever libraries with which binary_c was compiled, as well as the compiler with which Python was built (usually gcc, which is easily installed on most systems).
