@@ -69,30 +67,70 @@ For security reasons each build happens inside a container so that one build
 can't affect another build. For this to work a Podman container runs an API
 service so workers can themselfs execute builds inside containers.
 
-Please install Podman and test if it works:
+### Installation
+
+The server uses `podman-compose` to manage the containers. On a Debian based
+system, install the following packages:
+
+```bash
+sudo apt install podman-compose
+```
+
+A [Python library](https://podman-py.readthedocs.io/en/latest/) is used to
+communicate with Podman over a socket. To enable the socket either `systemd` is
+required or the socket must be started manually using the Podman itself:
+
+```bash
+# systemd
+systemctl --user enable podman.socket
+systemctl --user start podman.socket
+systemctl --user status podman.socket
+
+# manual (must stay open)
+podman system service --time=0 unix:/run/user/$(id -u)/podman/podman.sock
+```
+
+Now you can either use the latest ASU containers or build them yourself, run
+either of the following two commands:
 
-    podman run --rm -it docker.io/library/alpine:latest
+```bash
+# use existing containers
+podman-compose pull
 
-Once Podman works, install `podman-compose`:
+# build containers locally
+podman-compose build
+```
+The services are configured via environment variables, which can be set in a
+`.env` file
 
-    pip install podman-compose
+```bash
+echo "PUBLIC_PATH=$(pwd)/public" > .env
+echo "CONTAINER_SOCK=/run/user/$(id -u)/podman/podman.sock" >> .env
+# optionally allow custom scripts running on first boot
+echo "ALLOW_DEFAULTS=1" >> .env
+```
 
 Now it's possible to run all services via `podman-compose`:
 
-    # where to store images and json files
-    echo "PUBLIC_PATH=$(pwd)/public" > .env
-    # absolute path to podman socket mounted into worker containers
-    echo "CONTAINER_SOCK=/run/user/$(id -u)/podman/podman.sock" >> .env
-    podman-compose up -d
+```bash
+podman-compose up -d
+```
 
-This will start the server, the Podman API container and two workers. The first
-run needs a few minutes since available packages are parsed from the upstream
-server. Once the server is running, it's possible to request images via the API
-on `http://localhost:8000`. Modify `podman-compose.yml` to change the port.

+#### Squid Cache
+
+Instead of creating and uploading SNAPSHOT ImageBuilder containers everyday,
+only a container with installed dependencies and a `setup.sh` script is offered.
+ASU will automatically run that script and setup the latest ImageBuilder. To
+speed up the process, a Squid cache can be used to store the ImageBuilder
+archives locally. To enable the cache, set `SQUID_CACHE=1` in the `.env` file.
+
+To have the cache accessible from running containers, the Squid port 3128 inside
+a running container must be forwarded to the host. This can be done by adding
+the following line to the `.config/containers/containers.conf` file:
+
+```toml
+[network]
+pasta_options = [
+    "-a", "10.0.2.0",
+    "-n", "24",
+    "-g", "10.0.2.2",
+    "--dns-forward", "10.0.2.3",
+    "-T", "3128:3128"
+]
+```
+
+> If you know a better setup, please create a pull request.
