-# tlaternet-templates
-
-Website templates bundled with parcel.
-
-## Updating
-
-Firstly, updating the npm dependencies needs:
-
-```sh
-npm update --package-lock-only
-```
-
-After that, the NixOS derivations can be updated by running
-`generate.sh` in the `nix` subdirectory.
-
-### Note
-
-[Sharp](https://github.com/lovell/sharp/releases) is gloriously hard
-to install, because it depends on the most cutting-edge patch version
-of `vips`.
-
-Check which version it needs in the `package.json` of sharp, and then
-match this up which major sharp version matches up to which OS version
-of vips.
-
-Known versions:
-
-| Sharp | vips       | NixOS |
-| ----: | ---------: | ----: |
-| 28.*  | 8.10.6     |       |
-| 27.*  | 8.10.5     | 21.05 |
-| 26.*  | 8.10.0     | 20.09 |
