+# path_provider_linux
+
+The linux implementation of [`path_provider`].
+
+**Please set your constraint to `path_provider_linux: '>=0.0.y+x <2.0.0'`**
+
+## Backward compatible 1.0.0 version is coming
+The `path_provider` plugin has reached a stable API, we guarantee that version `1.0.0` will be backward compatible with `0.0.y+z`.
+Please use `path_provider_linux: '>=0.0.y+x <2.0.0'` as your dependency constraint to allow a smoother ecosystem migration.
+For more details see: https://github.com/flutter/flutter/wiki/Package-migration-to-1.0.0
+
+## Usage
+
+### Import the package
+
+To use this plugin in your Flutter linux app, simply add it as a dependency in
+your `pubspec.yaml` alongside the base `path_provider` plugin.
+
+_(This is only temporary: in the future we hope to make this package an
+"endorsed" implementation of `path_provider`, so that it is automatically
+included in your Flutter linux app when you depend on `package:path_provider`.)_
+
+This is what the above means to your `pubspec.yaml`:
+
+```yaml
+...
+dependencies:
+  ...
+  path_provider: ^1.5.1
+  path_provider_linux: ^0.0.1
+  ...
+```
+
+### Use the plugin
+
+Once you have the `path_provider_linux` dependency in your pubspec, you should
+be able to use `package:path_provider` as normal.
