 ## Installation
 
 > [!CAUTION]
-> The **Twilight** version is not really that reproducible over time while trying to download the src again due the way how the official Zen browser repository is managing
-> their releases, **a new release replaces the previous one and so on**. When using this version you should compromise yourself to update the flake with `nix flake update zen-browser`.
-> Or wait for a contribution that mitigates that behavior in that specific version of the browser.
+> The **twilight** package is not the official from [zen-browser/desktop](https://github.com/zen-browser/desktop). As you can
+> check in their [releases page](https://github.com/zen-browser/desktop/releases), there is only one Twilight version of the browser,
+> that's because there's only one tag available for that browser version, it means that every release replace the other, deleting the
+> artifacts that we referenced once and normally this happens everyday so the package we aim to create won't achieve the goal to be really
+> reproducible, for that reason we created a workaround to create releases and copy the artifacts from their repository in order to keep
+> alive indefinitely. If you don't trust about this method we're using or that the artifacts won't be infected will malware by the
+> repository owner or something else(I don't know, anything!), you can use the **twilight-official** package or simply keep yourself with **beta**.
