+## About
 
-> Lightweight, daily-built SteamCMD base image for game server automation.
+SteamCMD is a command-line version of the Steam client. It allows you to download and install games on a headless server. This container image builds daily and is available on [Docker Hub](https://hub.docker.com/r/gameservermanagers/steamcmd) as well as [GitHub Container Registry](https://github.com/GameServerManagers/docker-steamcmd/pkgs/container/steamcmd).
 
-## Quick Start
+## Tags
 
-Pull the latest image and open SteamCMD interactive prompt:
+- `latest`, `ubuntu` - Latest Ubuntu LTS release
+- `ubuntu-24.04` - Ubuntu 24.04 LTS 'Noble Numbat'
+- `ubuntu-22.04` - Ubuntu 22.04 LTS 'Jammy Jackalope'
+- `ubuntu-20.04` - Ubuntu 20.04 LTS 'Focal Fossa'
+- `ubuntu-18.04` - Ubuntu 18.04 LTS 'Bionic Beaver'
 
-```bash
-docker pull gameservermanagers/steamcmd:latest
-docker run -it --rm gameservermanagers/steamcmd:latest
-```
+## Usage
 
-Download (update) a dedicated server into the current host directory (example: CS2 / app 730):
+docker cli
 
 ```bash
-docker run -it --rm \
-  -v "$PWD:/data" \
-  gameservermanagers/steamcmd:latest \
-  +force_install_dir /data +login anonymous +app_update 730 validate +quit
+docker run -it gameservermanagers/steamcmd:latest
 ```
 
-Persist Steam content in a named volume:
-
-```bash
-docker volume create steamcmd-data
-docker run -it --rm -v steamcmd-data:/home/steam/Steam gameservermanagers/steamcmd:latest +login anonymous +quit
-```
-
-## Tags & Platforms
-
-| Tag(s) | Ubuntu Release | Notes |
-| ------ | -------------- | ----- |
-| `latest`, `ubuntu` | 24.04 LTS (Noble) | Alias to most recent LTS |
-| `ubuntu-24.04` | 24.04 LTS | Current LTS |
-| `ubuntu-22.04` | 22.04 LTS | Previous LTS |
-| `ubuntu-20.04` | 20.04 LTS | Legacy (receives security updates) |
-| `ubuntu-18.04` | 18.04 LTS | Legacy / nearing EOL upstream |
-
-Currently built for: `linux/amd64`.
-
-## Features
-
-- Daily scheduled build + build on Dockerfile changes
-- Non-root `steam` user (security best practice)
-- Minimal packages; apt caches cleaned
-- HEALTHCHECK (lightweight SteamCMD invocation)
-- Multi-version tag set for pinning
-
-## Usage Examples
-
-Anonymous login and quit (cache initialization):
-
-```bash
-docker run --rm gameservermanagers/steamcmd:latest +login anonymous +quit
-```
-
-Install/Update Valheim dedicated server (app 896660) into a local folder:
-
-```bash
-mkdir -p valheim && \
-docker run --rm -v "$PWD/valheim:/data" gameservermanagers/steamcmd:latest \
-  +force_install_dir /data +login anonymous +app_update 896660 validate +quit
-```
-
-Run with a different timezone:
-
-```bash
-docker run --rm -e TZ=UTC gameservermanagers/steamcmd:latest +login anonymous +quit
-```
-
-## Data Persistence
-
-Steam content is stored under `/home/steam/Steam` (owned by the non-root `steam` user). Mount a volume there to persist downloads across runs.
+Download Counter Strike: Global Offensive Dedicated Server to current host directory.
 
 ```bash
-docker run -v steamcmd-data:/home/steam/Steam gameservermanagers/steamcmd:latest +login anonymous +quit
+docker run -it -v $PWD:/data gameservermanagers/steamcmd:latest +force_install_dir /data +login anonymous +app_update 740 +quit
 ```
 
-## Configuration
-
-Common tunables (all optional):
-
-| Option | How | Purpose |
-| ------ | --- | ------- |
-| Timezone | `-e TZ=Europe/London` | Control tzdata (if installed) |
-| Working dir | `-w /home/steam` | Override working directory |
-| User mapping | `--user $(id -u):$(id -g)` | Run with host UID/GID (if perms needed) |
-
-Steam credentials (if you need a non-anonymous app):
-
-```bash
-docker run -it --rm gameservermanagers/steamcmd:latest +login <username> <password> +app_update <appid> +quit
-```
-
-Consider using Steam Guard / login tokens; avoid embedding secrets in shell history. Use `--env-file` for larger sets of env variables if needed.
-
-## Healthcheck
-
-The image defines a `HEALTHCHECK` that periodically performs a minimal anonymous login and metadata refresh. To disable at runtime, you can override with `--no-healthcheck` (Docker 25+) or build your own image `FROM` this one and use `HEALTHCHECK NONE`.
-
-## Security Notes
-
-- Runs as non-root `steam`
-- Network access only to Steam endpoints during operations
-- Keep host Docker updated; image alone does not mitigate kernel CVEs
-
-## Contributing
-
-Issues & PRs welcome. Before submitting:
-
-1. Run formatters: `prettier --write .`
-2. Run linters: super-linter workflow (or locally with the provided dev container)
-3. Keep layers minimal; squash RUN chains where reasonable

-## Troubleshooting
-
-Empty output directory:
-
-- Ensure the order: `+force_install_dir` comes BEFORE `+login` (SteamCMD requirement – it warns otherwise). If reversed, files may go to the default Steam library inside the container instead of your mounted directory.
-- Verify permissions: the container runs as user `steam` (UID 1000). If your host user ID differs and you see permission errors, try adding `--user $(id -u):$(id -g)` or pre-chown the host directory.
-- Add `validate` only when necessary; it forces extra file checks and can slow installs.
-
+## Notes
 
-Confirm installation path by adding `+app_status <appid>` before `+quit` to inspect state.
+This container is based off of the [steamcmd](https://github.com/steamcmd/docker) container and is primarily used for [LinuxGSM](https://linuxgsm.com) game servers.
