+# sotf-modloader
+
+A web page for installing, updating and removing Sons of the Forest mods with one click.
+
+Live site: https://justinoros.github.io/sotf-modloader/
+
+## For players
+
+1. Open the site in Chrome or Edge on Windows.
+2. Click **Choose game folder** and pick your Sons of the Forest install folder.
+3. Install RedLoader if it isn't installed yet, then install the mods you want.
+
+The page remembers your folder. Close the game before installing or updating.
+
+## How it works
+
+A GitHub Actions workflow runs every 6 hours, on every push to `main`, and on demand. It:
+
+- finds every repo owned by the account with the `sotf-mod` topic and mirrors the zip from its latest release
+- mirrors the latest RedLoader release
+- lists repos with the `sotf-tool` topic under Tools
+- publishes everything with a `manifest.json` to GitHub Pages
+
+The page writes files straight into the game folder using the browser's File System Access API.
+
+## Setup
+
+1. Settings, Pages, Source: **GitHub Actions**.
+2. Add the `sotf-mod` topic to each mod repo and `sotf-tool` to each tool repo.
+3. Actions, **Build and deploy**, **Run workflow**.
+
+## Mod release requirements
+
+- The latest release has a `.zip` asset containing `<Name>.dll` and `<Name>/manifest.json`.
+- `version` in `manifest.json` matches the release tag, so update detection works.
+- `platform` in `manifest.json` is `Client`, `Server` or `Universal`.
+
+After publishing a mod release, run the workflow manually to update the site right away.
