   • For Fedora:

     sudo dnf install meson ninja-build cdbs vala libvala-devel glib-devel gtk3-devel python3 python3-wheel python3-setuptools baobab glx-utils

2. Create a build folder:

   meson setup build --prefix=/usr

3. Compile comice-about:

   cd build && ninja

4. Install comice-about in your system:

   sudo USER="$HOME" ninja install

   NOTE: in case the application doesn't open, indicating failure getting RAM memory information. Please, run the next command:

To debug a Vala application, you must follow these steps:

1. Create build folder with type debug:

   meson setup build --prefix=/usr --buildtype=debug

2. Compile comice-about:

   cd build && ninja

3. Run the application in debug mode:

   gdb ./com.github.libredeb.comice-about

   The above command has the next output:
