 Fur is a programming language for the next millenium. In 1000 years, humans will likely still like
 furry animals, so Fur is named in their honor.
 
+## Installation
+
+1. Create and activate a virtual environment with Python 3. On most systems, this will look something like `python3 -m venv .env/ && .env/bin/activate`.
+2. Install dependencies from `requirements.txt` using `pip`: `pip install -r requirements.txt`.
+3. That's all!
+
+## Integration tests
+
+To run the unit tests, run `python integration_tests.py`.
+
+# Running
+
 Example Fur programs are in the `examples/` folder. The main compiler (`main.py`) compiles Fur
 programs to C. An example of usage:
 
-    ~/fur$ python3 main.py examples/01_hello.fur
+    ~/fur$ python main.py examples/01_hello.fur
     ~/fur$ gcc examples/01_hello.fur.c 
     ~/fur$ ./a.out
     Hello, world~/fur$

 exceptions, multithreading, modules, or anything resembling a standard library.  If that sounds
