I want to correct some typos and update some parts of the “HOWTO collection” ([https://www.swi-prolog.org/howto/index.txt](https://www.swi-prolog.org/howto/index.txt)) … where is the source (hopefully on github)?

The whole website is hiding at the [plweb repo](https://github.com/SWI-Prolog/plweb). This is in the readme to the repo, but basically:

```prolog
$ git clone https://github.com/SWI-Prolog/plweb.git
$ cd plweb
$ git submodule update --init

```

At this point I usually grep for stuff:

```prolog
$ rg 'Please contribute to this HOWTO'
www/howto/index.txt
14:Please contribute to this HOWTO. This website is now a [[wiki][</wiki/>]]!

```

PS: Since those are also in packages, you’d maybe have to do it as described [here](https://www.swi-prolog.org/howto/SubmitPatch.html), in the “How about submitting patches to a package?” section.
