-## Install from source
-
-**Prerequisites:**
-
-You need to have `flatpak` and `flatpak-builder` installed. For this example, we use `git` for downloading/updating Gajim's sources.
-
-### Download Gajim's sources
-
-In this example, we do a `git clone` of the repository, so you need to have `git` installed.
-Alternatively, you can also download the sources from our Gitlab via web browser.
-
-```bash
-git clone https://dev.gajim.org/gajim/gajim.git ~/Gajim
-cd ~/Gajim
-```
-
-*Note: Source tarballs and snapshots do _not_ include 'org.gajim.Gajim.yaml', which is necessary for installation via Flatpak.*
-
-### Install Gajim and dependencies
-
-Replace install path `~/Gajim/gajim_flatpak` with an install path of your choice.
-
-*Note: Remove `--user` if you want a system-wide installation.*
-
-```bash
-flatpak --user remote-add --from gnome https://sdk.gnome.org/gnome.flatpakrepo
-flatpak --user install gnome org.gnome.Platform//3.34
-flatpak --user install gnome org.gnome.Sdk//3.34
-flatpak-builder --repo=gajim_flatpak_repo ~/Gajim/gajim_flatpak ~/Gajim/flatpak/org.gajim.Gajim.yaml
-flatpak --user remote-add --no-gpg-verify gajim_flatpak_repo gajim_flatpak_repo
-flatpak --user install gajim_flatpak_repo org.gajim.Gajim
-flatpak run org.gajim.Gajim
-```
-
-That's it, you are now running Gajim via Flatpak!

-
-## How to update
-
-### Update Gajim's sources
-
-In this example, we use `git` to update the repository. You can also download the sources from our Gitlab via webbrowser.
-
-```bash
-cd ~/Gajim
-git pull --rebase
-```
-
-### Remove previous Flatpak directory
-
-```bash
-rm -r ~/Gajim/gajim_flatpak
-```
-
-### Install and update Gajim
-
-```bash
-flatpak-builder --repo=gajim_flatpak_repo ~/Gajim/gajim_flatpak ~/Gajim/flatpak/org.gajim.Gajim.yaml
-flatpak --user update
-flatpak run org.gajim.Gajim
-```
-
-Gajim is now updated.
-
-## Migrate your data
-
-When switching to Flatpak you might want to migrate your user data (accounts, history, ...) from your previous installation. Just copy your user data from/to the following directories:
-
-Copy `.local/share/gajim` -> `.var/app/org.gajim.Gajim/data/gajim`
-
-Copy `.config/gajim` -> `.var/app/org.gajim.Gajim/config/gajim`
