# Setting Up a Generic Project

Generic project support allows you to use Qt Creator as a code editor. You can change the way your project is built by modifying the `make` command in the Projects mode under Build Settings.

When you import a project, Qt Creator creates the following files that allow you to specify which files belong to your project and which include directories or defines you want to pass to your compiler: `.files`, `.includes`, and `.config`.

## Importing a Generic Project

To import an existing generic project:

1. Select File > New File or Project > Import Project > Import Existing Project.
2. In Import Existing Project, enter the project name and select the location of the project file you want to import.

   Qt Creator automatically generates the following files in the project directory:

   - .files
   - .includes
   - .config
   - .creator

When the project is successfully imported, Qt Creator creates the project tree in the sidebar.

After importing a generic project into Qt Creator, open it by selecting the `.creator` file.

## Working with Generic Project Files

For a generic project, you have to manually specify which files belong to your project and which include directories or defines you want to pass to your compiler.

## Specifying Files

The list of files for a generic project is specified in the `.files` file. When you first create a generic project, Qt Creator adds any files it recognizes to your project.

To add or remove files, edit the `.files` file in Qt Creator. Qt Creator recreates your project tree when you save the `.files` file. Alternatively, you can add and remove files using the context menu in the project tree.

If you frequently need to update the `.files` file, you can do so efficiently by using a script that updates the file for you. If the file is modified externally, you have to restart Qt Creator for the changes to take effect.

To update the `.files` on the Git repository use the following script:

      git ls-files "*.cpp" "*.h" > MyProject.files

## Specifying Include Paths

The include paths are specified in the `.includes` file, one include path per line. The paths can be either absolute or relative to the `.includes` file.

## Specifying Defines

The defines are specified in the `.config` file. The `.config` file is a regular C++ file, prepended to all your source files when they are parsed. Only use the `.config` file to add lines as in the example below:

      #define NAME value

## Creating a Run Configuration

Qt Creator cannot automatically determine which executable to run.

In the Projects mode under Run Settings, define the executable file to run:

1. Click Add and select Custom Executable.
2. Define the configuration name, the location of the executable, any additional arguments and the working directory.
