+# Arrow Flight SQL Adapter for PostgreSQL Documentation
+
+This folder contains the source for the public documentation.
+This is published to https://arrow.apache.org/flight-sql-postgresql/ by a GitHub Actions workflow
+when changes are merged to the main branch.
+
+## Dependencies
+
+It's recommended to install build dependencies and build the documentation
+inside a Python `venv`.
+
+To prepare building the documentation run the following on the root level of the project:
+
+1. Set up virtual environment if it was not already created
+   ```bash
+   python3 -m venv venv
+   ```
+1. Activate virtual environment
+   ```bash
+   source venv/bin/activate
+   ```
+1. Install documentation dependencies
+   ```bash
+   pip install -r docs/requirements.txt
+   ```
+
+## Build & Preview
+
+Run the provided script to build the HTML pages.
+
+```bash
+rake doc:html
+```
+
+The HTML will be generated into a `doc/build` directory.
+
+Preview the site on Linux by running this command.
+
+```bash
+firefox doc/build/index.html
+```
+
+## Release Process
+
+This documentation is hosted at https://arrow.apache.org/flight-sql-postgresql/
+
+When the PR is merged to the `main` branch of the Apache Arrow Flight SQL adapter for PostgreSQL
+repository, a [GitHub Actions workflow](https://github.com/apache/arrow-flight-sql-postgresql/blob/main/.github/workflows/doc.yaml) which:
+
+1. Builds the HTML content
+2. Pushes the HTML content to the [`asf-site`](https://github.com/apache/arrow-flight-sql-postgresql/tree/asf-site) branch in this repository.
+
+The Apache Software Foundation provides https://arrow.apache.org/,
+which serves content based on the configuration in
+[.asf.yaml](https://github.com/apache/arrow-flight-sql-postgresql/blob/main/.asf.yaml),
+which specifies the target as https://arrow.apache.org/flight-sql-postgresql/.
