-## Procedure
-1. Download Bash script to create new C++ projects 
-    ```bash
-    curl -O https://raw.githubusercontent.com/TimothyHelton/cpp_project_template/master/new_cpp_project.sh
-    chmod u+x new_cpp_project.sh
-    ```
-1. Create new C++ project
-    ```bash
-    ./new_cpp_project.sh NewProjectName
-    ```
-1. In the project top level **CMakeLists.txt**:
-    1. Line 2: Change the variable **MyProject** to the name of your project.
-        ```cmake
-        project(NewProject)
-        ```
-        - This variable will be used in a couple of different places.
-            - MyProject_run: will be the main executable name
-            - MyProject_lib: will be the project library name
-    1. Line 4: Set the version of C++ to use.  For example, let's set up the
-    NewProject to use C++ 11.
-        ```cmake
-        set(CMAKE_CXX_STANDARD 11)
-        ```
-1. Update project name and description in the `Doxyfile` located in the `docs`
-directory.
-    1. Update line `PROJECT_NAME`
-        1. This name will appear on each documentation page.
-    1. Update line `PROJECT_NUMBER`
-        1. This is the version number of your project.
-    1. Update line `PROJECT_BRIEF`
-        1. Any text entered here will also appear on each documentation page.
-        Try not to make this one too long.
-1. Reload the top CMake file.

-## CLION IDE Specific Instructions
-I started using an IDE from [JET Brains](https://www.jetbrains.com/) tailored
-for Python called [PyCharm](https://www.jetbrains.com/pycharm/) and thought
-it helped me write better code.
-I'd been wanting to learn C++ and decided to give JET Brains C/C++ IDE called
-[CLion](https://www.jetbrains.com/clion/) a try.
-The code completion, interactive suggestions, debugger, introspection tools,
-and built-in test execution are very handy.
-There are a couple extra details to set when using this IDE.
-
-1. The IDE allows you to mark directories with their desired purpose.
-To mark a directory right click on the directory name in the `Project` window
-and select `Mark Directory as` from the drop-down menu.
-    1. Mark the `src` directory as `Project Sources and Headers`
-    1. Mark the `tests/lib/googletest` directory as  `Library Files`
-1. Setup the `Run/Debug Configuration` by selecting `Edit Configurations...`
-from the pull-down menu from the run button (green triangle) in the upper right
-corner.
-    1. Update Doxygen Build to execute the unit test suite.
-        1. Select Doxygen from the Application menu on the left.
-        1. Choose the **executable** for Doxygen to be `Unit_Tests_run`.
-    1. Create a `Google Test` configuration
-        1. In the upper left corner select the plus symbol.
-        1. Chose `Google Test` from the drop-down menu.
-        1. Set **Name** to `Unit Tests`.
-        1. Set **Target** to `Unit_Tests_run`.
-
-## Wrap Up
-That should be all it takes to start writing code.
-If you find any issues or bugs with this repository please file an issue on
-[GitHub](https://github.com/TimothyHelton/cpp_project_template/issues).
-
-Hope you find this template useful and enjoy learning C++!
