+
+A [Chef](https://www.chef.io/) cookbook to unpack file archives.
+
+It supports `.tar`, `.tar.gz`, `.tar.bz2`, and `.zip` archive files.
+
+## Quick Start
+
+To download an unpack and archive:
+
+```ruby
+poise_archive 'https://example.com/myapp.tgz' do
+  destination '/opt/myapp'
+end
+```
+
+## Requirements
+
+Chef 12.1 or newer is required.
+
+## Platforms
+
+This cookbook supports all platforms (including Windows) but some Unix platforms
+(Solaris, AIX) may see very slow tar file unpacking when using the pure-Ruby fallback
+implementation.
+
+## Resources
+
+### `poise_archive`
+
+The `poise_archive` resource unpacks file archives.
+
+```ruby
+poise_archive '/tmp/myapp-1.2.0.tar' do
+  destination '/srv/myapp-1.2.0'
+end
+```
+
+A URL can also be passed as the source path, optionally with extra properties to
+be merged with `source_properties`.
+
+```ruby
+poise_archive 'http://example.com/myapp-1.2.0.zip' do
+  destination '/srv/myapp-1.2.0'
+end
+
+poise_archive ['http://example.com/myapp-1.2.0.zip', {headers: {'Authentication' => '...'}}] do
+  destination '/srv/myapp-1.2.0'
+end
+```
+
+#### Actions
+
+* `:unpack` – Unpack the archive. *(default)*
+
+#### Properties
+
+* `path` – Path to the archive. If relative, it is taken as a file inside
+  `Chef::Config[:file_cache_path]`. If a URL, it is downloaded to a cache file
+  first. *(name attribute)*
+* `destination` – Path to unpack the archive to. If not specified, the path of
+  the archive without the file extension is used. Required when unpacking from
+  a URL. *(default: auto)*
+* `group` – Group to run the unpack as.
+* `keep_existing` – Keep existing files in the destination directory when
+  unpacking. *(default: false)*
+* `source_properties` – Property key/value pairs to be applied to the
+  `remote_file` file resource when downloading a URL. *(default: {retries: 5})*
+* `strip_components` – Number of intermediary directories to skip when
+  unpacking. Works like GNU tar's `--strip-components`. *(default: 1)*
+* `user` – User to run the unpack as.
