 OpenMG is a GTK4 + Libadwaita manga reader written in C which uses `readmng` as its backend.
 
+[![Please do not theme this app](https://stopthemingmy.app/badge.svg)](https://stopthemingmy.app)
+
 ## Demostration
 
 ![Demostration vídeo of the manga reader.](https://gitea.sergiotarxz.freemyip.com/sergiotarxz/mangareader/raw/branch/main/demostration.gif)
 
 ## Installing the app.
 
+These are the installation methods supported currently.
+
+### Flatpak
+
+Download from https://gitea.sergiotarxz.freemyip.com/sergiotarxz/mangareader/releases the latest `openmg-x86_64-(version).flatpak` and run:
+
+```shell
+flatpak install openmg-x86_64-(version).flatpak
+```
+
+Beware that not being in Flathub yet you will have to come here again
+to get updates.
+
+### Gentoo
+
+```shell
+sudo eselect repository enable sergiotarxz
+echo 'app-misc/openmg ~amd64' | sudo tee -a /etc/portage/package.accept_keywords/zz-autounmask
+sudo emerge -a openmg --autounmask
+```
+
+If the installation ask you for a package masked for ~amd64 you can run
+`sudo etc-update`, upgrade the `package.accept_keywords` config file
+and try again the latest command of the installation instructions.
+
+
+## Build from source
+
+### Flatpak
+
 First fine tune the options in `me.sergiotarxz.openmg.json` for
 meson you want to have, for example preview images, complete list is
 on `meson_options.txt`
 
 ```shell
 flatpak --user remote-add --if-not-exists gnome-nightly https://nightly.gnome.org/gnome-nightly.flatpakrepo 
-flatpak install org.gnome.Sdk//master
-flatpak install org.gnome.Platform//master
-flatpak-builder --install --user build me.sergiotarxz.openmg.yml me.sergiotarxz.openmg
+flatpak --user install org.gnome.Sdk//master
+flatpak --user install org.gnome.Platform//master
+flatpak-builder --install --user build me.sergiotarxz.openmg.json me.sergiotarxz.openmg
 
 ```
 
+### Native
+
+```shell
+meson build
+meson compile -C build
+sudo meson install -C build
+```
+
 ## Running the app
 
+If using flatpak:
+
 ```shell
 flatpak run me.sergiotarxz.openmg
 ```
 
+If native installated:
+
+```shell
+openmg
+```
+
