 ## What's Revus?
 
-This application performs automatic reviews.
+Revus is an automated pull request (PR) review application that uses large language models (LLMs) to streamline and standardize code reviews.
 
-The README will be updated as the application is developed.
+## Install
+
+```bash
+pipx install revus
+```
+
+## Setup
+
+Create a configuration file called `revus.toml` with the following parameters:
+
+- `OPENAI_API_KEY` - your OpenAI API key, available [here](https://platform.openai.com/).
+- `model_name` - any available OpenAI model (default is gpt-4o-mini).
+- `file_types` - specify file types for the application to read using an array of strings (default is [“.py”]).
+- `language` - specify the language for review content (default is English).
+- `exclude_paths` - files or paths the application should ignore.
+- `custom_rules`- custom rules for review, if needed.
+
+## Usage
+
+To review changes with Revus, first add modified files to staging:
+```bash
+git add <file_name>
+```
+or add all files:
+```bash
+git add .
+```
+Then, run the application in the project folder:
+```bash
+revus
+```
+
+**Important**: Revus reviews each file individually, simplifying context management.
+
+*New features will be added soon.*
+
+## Additional Notes
+
+This project is in active development, currently in alpha, and may have limited or experimental features.
