+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux

+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).

+# C API client for openapi_petstore
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project. By using the [OpenAPI spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: 1.0.0
+- Package version: 
+- Generator version: 7.5.0-SNAPSHOT
+- Build package: org.openapitools.codegen.languages.CLibcurlClientCodegen
+
+## Installation
+You'll need the `curl 7.58.0` package in order to build the API. To have code formatted nicely, you also need to have uncrustify version 0.67 or later.
+
+# Prerequisites
+
+## Install the `curl 7.58.0` package with the following command on Linux.
+```bash
+sudo apt remove curl
+wget http://curl.haxx.se/download/curl-7.58.0.tar.gz
+tar -xvf curl-7.58.0.tar.gz
+cd curl-7.58.0/
+./configure
+make
+sudo make install
+```
+## Install the `uncrustify 0.67` package with the following command on Linux.
+```bash
+git clone https://github.com/uncrustify/uncrustify.git
+cd uncrustify
+mkdir build
+cd build
+cmake ..
+make
+sudo make install
+```
+
+## Compile the sample:
+This will compile the generated code and create a library in the build folder which has to be linked to the codes where API will be used.
+```bash
+mkdir build
+cd build
+// To install library to specific location, use following commands
+cmake -DCMAKE_INSTALL_PREFIX=/pathtolocation ..
+// for normal install use following command
+cmake ..
+make
+sudo make install
+```
+## How to use compiled library
+Considering the test/source code which uses the API is written in main.c(respective api include is written and all objects necessary are defined and created)
+
+To compile main.c(considering the file is present in build folder) use following command
+-L - location of the library(not required if cmake with normal installation is performed)
+-l library name
+```bash
+gcc main.c -L. -lopenapi_petstore -o main
+```
+Once compiled, you can run it with ``` ./main ```
+
+Note: You don't need to specify includes for models and include folder separately as they are path linked. You just have to import the api.h file in your code, the include linking will work.
