@@ -28,14 +28,52 @@ Currently, we target the following package types:
 - pacman (Arch Linux, Manjaro)
 - zip (any, portable)
 
-Please refer to your distribution's documentation on information on how to install these packages, but we try some of them like this:
-- `AppImage` are runnable binaries, so to install them just run them. 
-- `deb` can be installed running: `sudo dpkg -i <downloaded file>.deb`
-- `pacman` can be installed running: `sudo pacman -U <downloaded file>.pacman`
-  > AUR builds are highly recommended instead. Install [notion-app](https://aur.archlinux.org/packages/notion-app/) or [notion-app-enhanced](https://aur.archlinux.org/packages/notion-app-enhanced) respectively.
+#### AppImage
+
+AppImages are binary installers that are compatible with any Linux distribution, to install them you can just run them.
+
+#### deb
+
+You can add our repository to your package manager by running
+
+```
+sudo apt-add-repository 'deb [trusted=yes] https://apt.fury.io/notion-repackaged/ /'
+```
+
+> :information_source: For the new repository to be able to provide our packages, you will have to run `sudo apt update` first
+
+With that you will be able to install `notion-app` or `notion-app-enhanced` using `sudo apt install <package name>`
+
+Alternatively, download manually and run `sudo dpkg -i <downloaded file>.deb` to install the package.
+
+#### rpm
+
+> :warning: These instructions assume you are using dnf/yum in Fedora or alikes. Instructions might vary depending on the distribution you are using.
+
+You can add our repository to your package manager by creating the file `/etc/yum.repos.d/notion-repackaged.repo` with the following contents:
+
+```
+[notion-repackaged]
+name=Notion Repackaged Repo
+baseurl=https://yum.fury.io/notion-repackaged/
+enabled=1
+gpgcheck=0
+```
+
+With that you will be able to install `notion-app` or `notion-app-enhanced` using `sudo dnf install <package name>`
+
+Alternatively, download manually and run `sudo rpm -i <downloaded file>.rpm` to install the package.
+
+#### pacman
+
+You can install the [notion-app](https://aur.archlinux.org/packages/notion-app/) or [notion-app-enhanced](https://aur.archlinux.org/packages/notion-app-enhanced) packages for the vanilla or enhanced versions respectively.
+
+Alternatively, download manually and run `sudo pacman -U <downloaded file>.pacman` to install the package.
 
 ### MacOS
 
+> :warning: As of now, the M1 (arm64) build is non-functional due to [electron-userland/electron-builder#5850](https://github.com/electron-userland/electron-builder/issues/5850), you can try using the regular build thanks to Rosetta. You can also try using the arm64 zip build that might work.
+
 We also build the enhanced variant for MacOS but there are no concrete instructions as I have no way of trying the builds for myself.
 
 In theory, you should be able to download the `dmg` build and drag it to your dock to install it.
