__NOTE:__ To run on a Flink cluster, Flink-Agents requires a stable release of
Flink version 1.20.3 or higher. We highly recommend using the **latest stable
release of your chosen Flink minor version** (e.g., for minor version 2.2, use
the latest 2.2.x release).

-## Install Apache Flink
+## Prerequisites
+
+Both the script-based and manual installation paths require:
+
+* **Java 11+** on your `PATH`. Java 21+ is recommended when using the Java API
— see the table below for the version-specific limitations.
+* **Python 3.10, 3.11, or 3.12** (only required if you plan to use the Python
API or PyFlink).
+
+For building Flink Agents from source, you additionally need:
+- Unix-like environment (Linux, macOS, Cygwin, or WSL)
+- Git
+- Maven 3
+
+### Java Versions
+
+For running an agent built with the **Python API**, you can use any Java
version 11 or higher.
+
+When using the **Java API**, there are some functionality limitations for
earlier Java versions, as detailed below:
+
+| Java Version | Limitations |
+|--------------|------------------------|
+| Java 21+ | No limitations. |
+| Java 11-20 | Async execution is unavailable. |
+
+{{< hint info >}}
+**Note**: If you want to use python 3.12, you need install Flink above 2.1
(including 2.1).
+{{< /hint >}}
+
+## Quick install (recommended)
+
+The `install.sh` script provisions everything you need: it downloads Apache
Flink, creates a Python virtual environment, installs `flink-agents` and
`apache-flink` into it, and copies the required JARs into `$FLINK_HOME/lib`.
+
+Run the one-liner from any directory you want the virtual environment created
in:
+
+```shell
+curl -fsSL
https://raw.githubusercontent.com/apache/flink-agents/main/tools/install.sh |
bash
+```
+
+### What the script does
+
+- Verifies that Java 11+ is available on your `PATH`. It does **not** install
Java for you.
+- Downloads and extracts Apache Flink into `$INSTALL_DIR` (default:
`$HOME/.local/flink`), or reuses an existing `$FLINK_HOME` if you tell it not
to install Flink.
+- Creates a Python virtual environment (default: `./.flink-agents-env`) and
runs `pip install flink-agents apache-flink` inside it.
+- Copies `flink-python-<version>.jar`, `flink-agents-dist-common-*.jar`, and
the version-specific `flink-agents-dist-*` thin JAR into `$FLINK_HOME/lib`.
+- Runs post-install verification (Flink binary, Python package, and JAR
presence) before exiting.
