+# Swagger Codegen Ignore
+# Generated by swagger-codegen https://github.com/swagger-api/swagger-codegen
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# IO.Swagger - the PowerShell module for the Swagger Petstore
+
+This is a sample server Petstore server.  You can find out more about Swagger at [http://swagger.io](http://swagger.io) or on [irc.freenode.net, #swagger](http://swagger.io/irc/).  For this sample, you can use the api key `special-key` to test the authorization filters.
+
+This PowerShell module is automatically generated by the [Swagger Codegen](https://github.com/swagger-api/swagger-codegen) project:
+
+- API version: 1.0.0
+- SDK version: 
+- Build date: 2017-06-09T17:28:25.415+04:00
+- Build package: io.swagger.codegen.languages.PowerShellClientCodegen
+
+<a name="frameworks-supported"></a>
+## Frameworks supported
+- .NET 4.0 or later
+- PowerShell 3.0 or later
+
+<a name="dependencies"></a>
+## Dependencies
+- [RestSharp](https://www.nuget.org/packages/RestSharp) - 105.1.0 or later
+- [Json.NET](https://www.nuget.org/packages/Newtonsoft.Json/) - 7.0.0 or later
+
+The DLLs included in the package may not be the latest version. We recommend using [NuGet] (https://docs.nuget.org/consume/installing-nuget) to obtain the latest version of the packages:
+```
+Install-Package RestSharp
+Install-Package Newtonsoft.Json
+```
+
+NOTE: RestSharp versions greater than 105.1.0 have a bug which causes file uploads to fail. See [RestSharp#742](https://github.com/restsharp/RestSharp/issues/742)
+
+<a name="installation"></a>
+## Installation
+Run the following command to generate the DLL
+- [Windows] `Build.ps1`
+
+Then import module from the .\src\IO.Swagger folder:
+```powershell
+using IO.Swagger.IO.Swagger\API;
+using IO.Swagger.Client;

+# Swagger Codegen Ignore
+# Generated by swagger-codegen https://github.com/swagger-api/swagger-codegen
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md
