 * Simplify expressions
 * It can do maths faster than you
 
+# Installation
+
+Equator can be installed from PyPi. Run the command
+```
+pip3 install equatorpy
+```
+
 # Usage:
 
 ## Start-up:
-Run the file `equator.py` in the top-level directory. For example, `python3 equator.py`. The program has been tested on Windows and Linux (Ubuntu), but not MacOS. It might work, but it might not.
+Equator can be run directly through the Python module. Run the command
+```
+python3 -m equator
+```
+Alternatively, Equator can be invoked directly using the command
+```
+equator
+```
+The program has been tested on Windows and Linux (Ubuntu), but not MacOS. It might work, but it might not.
 * If no arguments are provided, the program launches into a full interpreter, built using the Curses library.
 * If it is started with the argument `json`, then its output will be in a JSON format, where each line of input is treated as one set of equations and expressions. Each input will have one line of respective output, in [JSON format](https://github.com/MiguelGuthridge/Equator/wiki/JSON-Format-Specification).
 * If it is started with the argument `ev`, then it will run a quick evaluation on the following argument. For example `equator ev "1 + 1"` would print `2`.

+* Equations or expressions are separated by semicolons
+
+# Development
+
+When working with Equator, it is recommended to work with a virtual environment.
+
+After `git clone`ing the repository, set up a virtual environment using [these
+instructions](https://docs.python.org/3/library/venv.html), then install the
+required dependencies using the command
+```
+pip3 install -r requirements.txt
+```
+or if you're on Windows
+```
+pip install -r requirements_windows.txt
+```
+
+You should then be able to debug or develop the interpreter normally.
