+Use the Volume-cache plugin to preserve files and directories between builds.
+Because it uses a mounted volume, it requires repositories using it to enable the *"Trusted"* flag.
+
+## Config
+The following parameters are used to configure the plugin:
+- **restore** - instruct plugin to restore cache, can be `true` or `false`
+- **rebuild** - instruct plugin to rebuild cache, can be `true` or `false`
+- **mount** - list of folders to cache
+
+## Examples
+```yaml
+pipeline:
+  restore-cache:
+    image: drillster/drone-cache
+    restore: true
+    mount:
+      - ./node_modules
+    # Mount the cache volume, needs "Trusted"
+    volumes:
+      - /tmp/cache:/cache
+
+  build:
+    image: node
+    commands:
+      - npm install
+
+  rebuild-cache:
+    image: drillster/drone-cache
+    rebuild: true
+    mount:
+      - ./node_modules
+    # Mount the cache volume, needs "Trusted"
+    volumes:
+      - /tmp/cache:/cache
+```
+
+The example above illustrates a typical Node.js project Drone configuration. It caches the `./node_modules` directory to a mounted volume on the host system: `/tmp/cache`. This prevents `npm` from downloading and installing the dependencies for every build.
