+# PgBouncer
+
+PgBouncer is a lightweight connection pooler for PostgreSQL that helps optimize database connections by reusing established sessions.
+
+## Overview
+
+This directory contains all the necessary files to build and run PgBouncer as part of the Poixpixel Discord Bot project. It is based on Alpine Linux and includes support for c-ares.
+
+## Contents
+
+- **Dockerfile**: Builds the PgBouncer image with c-ares support.
+- **entrypoint.sh**: Generates and configures the PgBouncer configuration file at container startup.
+
+## Building the Docker Image
+
+To build the PgBouncer Docker image, run:
+
+```sh
+docker build -t my-pgbouncer ./docker/pgbouncer
+```
+
+## Running the Container
+
+Run the container with your desired environment variables. For example:
+
+```sh
+docker run --rm \
+    -e DATABASE_URL="postgres://user:pass@postgres-host/database" \
+    -p 5432:5432 \
+    my-pgbouncer
+```
+
+Or, if you would like to use separate environment variables:
+
+```sh
+docker run --rm \
+    -e DB_USER=user \
+    -e DB_PASSWORD=pass \
+    -e DB_HOST=postgres-host \
+    -e DB_NAME=database \
+    -p 5432:5432 \
+    my-pgbouncer
+```
+
+You can also use the prebuilt image. For example:
+
+```sh
+docker run --rm \
+    -e DB_USER=user \
+    -e DB_PASSWORD=pass \
+    -e DB_HOST=postgres-host \
+    -e DB_NAME=database \
+    -p 5432:5432 \
+    ghcr.io/ahmadk953/poixpixel-discord-bot-pgbouncer
+```
+
+## Customizing Your Setup
+
+- **Dockerfile**: Modify build arguments or dependencies as needed.
+- **entrypoint.sh**: Adjust how the configuration file is generated and updated.
+- **Environment Variables**: Almost all settings found in the `pgbouncer.ini` file can be set as environment variables, except for a few system-specific configuration options. For an example, check out [the example Docker compose file](../../docker-compose.yml). For all configuration options, check the [PgBouncer configuration documentation](https://www.pgbouncer.org/config.html).
+- **Configuration File**: You can specify your own `pgbouncer.ini` file by mounting it as a volume like so:
+```sh
+docker run --rm \
+    -e DB_USER=user \
+    -e DB_PASSWORD=pass \
+    -e DB_HOST=postgres-host \
+    -e DB_NAME=database \
+    -v PgBouncer.ini:/etc/PgBouncer/PgBouncer.ini:ro \
+    -p 5432:5432 \
+    ghcr.io/ahmadk953/poixpixel-discord-bot-pgbouncer
+```
+
+## License
+
+See the [LICENSE](../../LICENSE) file in the root of the project for licensing details.
