 The buetow.org internet site
 ============================
 
-This is the source code of my personal internet site and blog engine. All content is written in Gemini Gemtext format, but the script `buetow.org.sh` generates multiple other static output formats from it. You can reach the site(s)...
+This repository contains the static files of my internet site.  [gemini://buetow.org](gemini://buetow.org) and [https://buetow.org](https://buetow.org). 
 
-* Via Gemini/Gemtext: [gemini://buetow.org](gemini://buetow.org) (You need a Gemini client for this)
-* Via "normal" HTML: [https://buetow.org](https://buetow.org) (Actually it's XHTML Transitional 1.0)
-* Via [Gemini Webproxy](https://portal.mozz.us/gemini/buetow.org)
-* Via [GitHub Markdown](https://github.com/snonux/buetow.org/blob/content-md/index.md)
-* Via [GitHub Page](https://snonux.github.io/buetow.org) (from Markdown)
-
-Have a look at the `content-*` branches of this buetow.org Git project for source samples.
-
-## Software I use to maintain this site
-
-* Text editor: [Vim](https://www.vim.org)
-* Gemini server: [a-h/gemini](https://github.com/a-h/gemini)
-* Bash
-* ShellCheck (if you want to run the tests)
-* Web server: [Apache HTTPD](https://httpd.apache.org) (for "normal" HTML site)
-* Obviously, I am also using GitHub for source code and GitHub Page hosting.
-
-# Getting started
-
-## Requirements
-
-These are the requirements of the `buetow.org.sh` static site generator script:
-
-* GNU Bash 5.x or higher
-* ShellCheck installed
-* GNU Sed
-* GNU Date
-* Git
-
-The script was tested on a recent Fedora Linux. For *BSD or macOS you would need to install GNU Sed, GNU Date, and a newer version of Bash.
-
-## Usage
-
-So you want such a pretty internet site too?
-
-To get started, just clone this repo (master branch) and run `./buetow.org.sh`. You will will be prompted with further instructions.
-
-You will notice soon, that all site content is located in `../buetow.org-content/` (you can configure the `BASE_CONTENT_DIR` in `buetow.org.conf`). There is one sub-directory per output format, e.g.:
-
-```
-../buetow.org-content/gemtext
-../buetow.org-content/html
-../buetow.org-content/md
-../buetow.org-content/meta
-```
-
-### Alternative config file path
-
-If you don't want to mess with `buetow.org.conf`, you can use an alternative config file path in `~/.config/buetow.org.conf`, which takes precedence if it exists. Another way is to set the `CONFIG_FILE_PATH` environment variable, e.g.:
-
-```
-export CONFIG_FILE_PATH=~/.config/my-site.geek.conf
-./buetow.org.sh --generate
-```
-
-### What is what
-
-Whereas, you only want to directly edit/add/remove content in the `gemtext` folder. The `buetow.org.sh` then will take the Gemtext and update all other formats accordingly. Summary of what is what:
-
-* `gemtext`: The Gemini Gemtext markup files of the internet site.
-* `html`: The XHTML version of it.
-* `md`: The Markdown version of it. 
-* `meta`: Some meta data of all Gemtext blog posts. It's used by `buetow.org.sh` internally for Atom feed generation.
-
-### Special HTML configuration
-
-You will find the `./header.html.part` and `./footer.html.part` files, they are minimal template files for the HTML generation.
-
-### Special Markdown configuraiton
-
-`buetow.org.sh` will never touch the `../buetow.org-content/md/_config.yml` file (if it exists). That's a special configuration file for GitHub Pages.
-
-## Store all formats in Git
-
-I personally have for each directory in `../buetow.org-content/` a separate Git repository configured. So whenever something has changed it will be updated/added/removed to version control. The following will run the generator and commit everything to Git:
-
-```
-USE_GIT=yes ./buetow.org --generate
-```
-
-And the following will additionally perform a `git pull` and `git push` afterwards;
-
-```
-USE_GIT=yes GIT_PUSH=yes ./buetow.org --generate
-```
-
-You could add the `USE_GIT` and `GIT_PUSH` options to the `buetow.org.conf` config file too.
-
-## Publishing a blog post
-
-All what needs to be done is to create a new file in `./gemtext/gemfeed/YYYY-MM-DD-article-title-dash-separated.gmi`, whereas `YYYY-MM-DD` defines the publishing date of the blog post.
-
-A subsequent `./buetow.org.sh --generate` will then detect the new post and link it from `$BASE_CONTENT_DIR/gemtext/gemfeed/index.gmi`, link it from the main index `$BASE_CONTENT_DIR/gemtext/index.gmi`, and also add it to the Atom feed at `$BASE_CONTENT_DIR/gemtext/gemfeed/atom.xml`. The first level 1 Gemtext title (e.g. `# Title`) will be the displayed link name. `YYYY-MM-DD` will be the publishing date. There are various other settings, such as Author - they come from the `buetow.org.conf` configuration file.
-
-Once all of that is done, the `buetow.org.sh` script will convert the new post (plus all the indices and the Atom feed) to the other formats too (e.g. HTML, Markdown).
-
-You can also have a look at `$BASE_CONTENT_DIR/meta/gemfeed`. There is a meta file for each blog post stored. These meta files are required for the generation of the Atom feed. You can edit these meta files manually and run `./buetow.org.sh --generate` or `./buetow.org.sh --feed` again, in case you want to change some of the Atom feed content.
-
-## Finito
-
-After running `./buetow.org --genreate` you will have all static files ready to be published. But before you do that you could preview the content with `firefox ../buetow.org-content/html/index.html` or `glow ../buetow.org-content/md/index.md` (you get the idea).
-
-Have also a look at the generated `atom.xml` files. They make sense (at least) for Gemtext and HTML.
-
-Now it is up to you to setup a Gemini server for the Gemtext, a Webserver for the HTML and/or a GitHub page for the Markdowns.
