 template:
  * A LaTeX backend (e.g. [TeX Live](https://www.tug.org/texlive) or [MikTeX](https://miktex.org))
  * A comfortable text editor (e.g. [Notepad++](https://notepad-plus-plus.org)) or a LaTeX frontend (e.g. [TeXstudio](http://www.texstudio.org))
- * A BibTeX manager (e.g. [JabRef](http://www.jabref.org))
+   * [Visual Studio Code](https://code.visualstudio.com/) also has a quite usable [LaTeX extension](https://marketplace.visualstudio.com/items?itemName=James-Yu.latex-workshop)
+ * A bibliography manager (e.g. [JabRef](http://www.jabref.org))
+
+You may also use a Docker-based workflow. See below for details.
+
 
 ## HowTo
 
+See [the automatically created PDF file](https://git.imp.fu-berlin.de/agse/thesis-template/-/jobs/artifacts/main/raw/thesis.pdf?job=compile-thesis)
+for more documentation on the "configuration options" of your document.
+
 To create a PDF file manually (i.e. if you don't use a LaTeX frontend), you need to call:
- * `pdflatex thesis`
- * `bibtex thesis`
- * `pdflatex thesis`
- * `pdflatex thesis`
+```bash
+latexmk -pdf thesis
+```
+
+### Alternative
+
+You can also use a Docker image to compile the LaTeX source:
+
+```bash
+docker run --rm -it -v $(pwd):/home danteev/texlive latexmk -pdf thesis.tex
+
+# For continuous builds
+docker run --rm -it -v $(pwd):/home danteev/texlive latexmk -pdf -pvc thesis.tex
+```
