 `workshop-sync` is a command line tool for keeping a game server or client addon folder aligned
 with one or more Steam Workshop collections.
 
-The CLI expects one or more Workshop collection IDs, an addon output directory, and a Steam Web API
-key. The API key can be passed with `--api-key` or provided through the `STEAM_WEB_API_KEY`
-environment variable. Steam Web API keys can be created at
-[steamcommunity.com/dev/apikey](https://steamcommunity.com/dev/apikey).
+## Prebuilt binaries
 
-It reads the collections, resolves their child addons, downloads missing or outdated `.vpk` files,
-and can remove old managed files that are no longer part of the requested collections.
+Prebuilt binaries for Linux, Windows, and macOS are available from the
+[continuous release](https://github.com/rihi/workshop-sync/releases/tag/continuous). This prerelease
+is rebuilt from the latest commit on `main`, so its files are replaced after every successful build.
 
-```bash
-cargo run -- --addons-dir ./addons --api-key <steam-web-api-key> 123456789
-```
-
-Multiple collections can be synced in one run:
+Download the archive for your platform, extract it, and run `workshop-sync` (`workshop-sync.exe` on
+Windows).
 
-```bash
-cargo run -- -a ./addons -k <steam-web-api-key> 123456789 987654321
-```
+## Usage
 
-The tool stores managed addon files with names like:
-
-```text
-workshopsync_<publishedfileid>_<hcontent_file>.vpk
-```
-
-On each run, it compares the requested Workshop addons with the managed files already in the addon
-directory. Missing addons are downloaded, outdated addons are replaced, and files that no longer
-belong to the requested collections are reported as stale.
-
-Stale files are only removed when `--delete-stale` is passed:
+Pass an addon directory, a [Steam Web API key](https://steamcommunity.com/dev/apikey), and one or
+more Workshop collection IDs:
 
 ```bash
-cargo run -- --addons-dir ./addons --api-key <steam-web-api-key> --delete-stale 123456789
+workshop-sync --addons-dir ./addons --api-key <steam-web-api-key> --delete-stale 123456789 987654321
 ```
 
-Use `--dry-run` to print the sync plan without downloading, replacing, or deleting files:
+The command installs or updates addons from the specified collections and
+removes previously managed addons that are no longer included, effectively keeping the addon
+directory in sync with those collections.
 
-```bash
-cargo run -- --addons-dir ./addons --api-key <steam-web-api-key> --dry-run 123456789
-```
+The API key can also be provided through the `STEAM_WEB_API_KEY` environment variable.
 
-Downloads run concurrently. The default concurrency is 4 and can be changed with `--concurrency`.
+Useful options:
 
-If a download fails after making progress, it is retried. `--max-stalled-retries` controls how many
-failures without file growth are allowed before giving up on that addon. Logging uses the tracing
-filter from `--log-level` or `RUST_LOG`, with `info` as the default.
+- `--dry-run` prints the planned changes without modifying files.
+- `--delete-stale` removes managed addons that are no longer in the collections.
+- `--concurrency <number>` sets the number of concurrent downloads (default: `4`).
+- `--max-stalled-retries <number>` limits retries for downloads that stop making progress.
+- `--log-level <filter>` sets the tracing filter and defaults to `info`.
 
-Use `--help` to see all the available arguments:
+Run the built-in help for the complete argument list:
 
 ```bash
-cargo run -- --help
+workshop-sync --help
