 ## Installation
 
 There are two options for running the program:
 
-  1. Download a Python interpreter, create the environment, and run script (Python required).
-  2. Download the compiled program file (created using [Nuitka](https://nuitka.net/)), unzip, and run (Python not required).
+  1. Download a Python interpreter, create the virtual environment, and run script (Python required).
+  2. Access the [web app](https://regulatorystudies.shinyapps.io/regulation-digest/) and either browse or download the FR documents in .csv format (Python not required).
 
-This README document focuses on option 1. Please reach out to <mfebrizio@gwu.edu> for access to the compiled program.

-## Compiling the Program
+## Deploying the Web App
 
-The program is compiled for distribution using the Nuitka python package (see [Use Case 4 - Program Distribution](https://nuitka.net/doc/user-manual.html#use-case-4-program-distribution) in the User Manual). Standalone mode produces a folder for distribution to other systems.
+The program was developed as a [web app](https://regulatorystudies.shinyapps.io/regulation-digest/) for distribution using the [Shiny for Python](https://shiny.posit.co/py/) package. The app is deployed using the [shinyapps.io hosted service](https://regulatorystudies.shinyapps.io/regulation-digest/).
 
-The following commands create a `.dist` folder containing the executable `retrieve_clips_program.exe`. The `--include-data-files` flag is used to include the metadata required to identify parent agencies associated with each document. You can specify the source of the data files and the end location of the files in the compiled dist using `--include-data-files=<source>=<target>`.
-
-```{cmd}
-cd "PATH/TO/PROJECT/ROOT"
-
-conda activate regdigest
-
-python -m nuitka --standalone --remove-output --include-data-files=./data/agencies_endpoint_metadata.json=data/agencies_endpoint_metadata.json retrieve_documents.py
-```
+After installing and configuring the `rsconnect-python` package (see instructions [here](https://docs.posit.co/shinyapps.io/guide/getting_started/#working-with-shiny-for-python)), you can deploy updates to the app using the `deploy.bat` script in the repository.
