+# Fast HTML2PDF API
+
+Welcome to the **Fast HTML2PDF API**! 🚀
+
+This is a lightweight version of the software used at [html2pdfapi.com](https://html2pdfapi.com).
+
+It provides a basic yet performant wrapper along with additional features to enhance the standard Puppeteer experience.
+
+For usage in commercial services, please refer to the `license.txt` file located in this repository.
+
+We are a small team, and any support to further develop this product is greatly appreciated! 🙏
+
+## Getting Started with Development
+
+To get started, run the following commands:
+
+```
+npm i
+npm run dev
+```
+
+## Build and Run in Docker
+
+### Prerequisites
+
+- Docker installed on your system
+
+### Build the Docker image
+
+To build the Docker image, run the following command in the project root directory:
+
+```
+docker build --platform linux/amd64 . -t render
+```
+
+### Run the Docker container
+
+To run the Docker container, use the following command:
+
+```
+docker run --platform linux/amd64 -p 3000:3000 render
+```
