To install Composer, go at https://getcomposer.org.

Create a composer.json for your project in a new directory (ex: myproject) which will be dedicated to your application. Here is an example of its content:

{
    "name": "myorganisation/myproject",
    "type": "application",
    "require": {
        "jelix/jelix": "dev-jelix-1.7.x"
    },
    "minimum-stability": "stable"
}

You can also create this file with the command composer init.

In the directory, launch Composer to install Jelix packages:

cd myproject
composer install

A new directory vendor appears, in which Jelix and other libraries are installed. Jelix is then into vendor/jelix/jelix/.

In other page of the manual, if it is refered to the lib/ directory of Jelix, it is vendor/jelix/jelix/lib/.

The command create-jelix-app is into vendor/bin/.

Go into the download page of jelix.org to download a tar.gz or a zip package of Jelix. This archive contains all files of the framework and other libraries.

Then extract files from the archive with winzip, unzip, tar or any other tools supporting the zip or tar.gz format. Example with tar:

  tar xvzf jelix-1.7.2.tar.gz

A directory jelix-1.7.2 is then created containing a lib/ and a bin/ directory. Move these directories into your project directory.

The command create-jelix-app is into bin/.

In a console, change directory to where is create-jelix-app, and run:

php create-jelix-app /path/to/myproject/myapp

myapp will be the name of your application.

create-jelix-app create a myapp/ directory with the given path. Its content is:

  myapp/
     app/
        system/    static configuration files of your application
        responses/ contains a class implementing a default HTML response.
        themes/    different possible themes of your application
        overloads/ will contain different files you will choose to overload
                   from those in your modules
     install/      scripts and files to initialize the application
     modules/      modules owned by your application
     plugins/      plugins owned by your application
     temp/         all temporary files will be stored in it
     var/
         config/   configuration files of your application for the current environment
         log/      optional log files
         themes/   themes installed during the life of the application
         overloads/ like app/overloads, but for files created during the life of the application.
     www/          root of the public files, readable directly by a browser 

Now that your application is created, you can test it by launching a web server, like the PHP's one (use it only for development!).

cd myapp
php -S localhost:8080 -t www

Then go to http://localhost:8080 with your browser.

If you want to use an other web server, like Apache or Nginx, you have more settings. See the next chapter.
