 Welcome to eesunhong's documentation!
 =====================================
 
+Installation
+------------
+
+To install ``eesunhong`` use
+
+.. code:: shell
+
+    pip install eesunhong
+
+Although not required, as is generally good practice for any development project, we highly recommend creating a separate virtual environment for each distinct project. For example, via Conda, creating a virtual environment for a project using ``eesunhong`` might look like
+
+.. code::
+
+    conda create -n eesunhong_env python=3.11
+
+Then before working, be sure to activate your environment with
+
+.. code:: shell
+
+    conda activate eesunhong_env
+
+Then install ``eesunhong`` within this environment.
