+
+## Prerequisites
+
+Assuming you understand in principle how to work with our git. Now you need:
+
+* a system with running Docker installation
+* all necessary access/execution rights
+* a local clone of the repository in the directory `./hpc-compendium`
+
+Remark: We have seen problems running the container an ecryptfs filesystem. So you might
+want to use `/tmp` as root directory.
+
+## Preparation
+
+Build the docker image. This might take a bit longer, but you have to
+run it only once in a while (when we have changed the Dockerfile).
+
+```Bash
+cd hpc-compendium
+docker build -t hpc-compendium . 
+```
+
+## Working with the Docker Container
+
+Here is a suggestion of a workflow which might be suitable for you.
+
+### Start the Local Web Server
+
+The command(s) to start the dockerized web server is this:
+
+```Bash
+docker run --name=hpc-compendium -p 8000:8000 --rm -it -w /docs \
+  -v /tmp/hpc-compendium/doc.zih.tu-dresden.de:/docs:z hpc-compendium bash \
+  -c 'mkdocs build  && mkdocs serve -a 0.0.0.0:8000'
+```
+
+To follow its progress let it run in a single shell (terminal window)
+and open another one for the other steps.
+
+You can view the documentation via
+[http://localhost:8000](http://localhost:8000) in your browser, now.
+
+You can now update the contents in you preferred editor.
+The running container automatically takes care of file changes and rebuilds the
+documentation.
+
+With the details described below, it will then be easy to follow the guidelines
+for local correctness checks before submitting your changes and requesting
+the merge.
+
+### Run the Proposed Checks Inside Container
+
+Remember to keep the local web server running in the other shell.
+
+First, change to the `hpc-compendium` directory and set the environment
+variable DC to save a lot of keystrokes :-)
+
+```Bash
+export DC='docker exec -it hpc-compendium bash -c '
+```
+
+and use it like this...
+
+#### Linter
+
+If you want to check whether the markdown files are formatted
+properly, use the following command:
+
+```Bash
+$DC 'markdownlint docs'
+```
+
+#### Link Checker
+
+To check a single file, e.g.
+`doc.zih.tu-dresden.de/docs/software/big_data_frameworks.md`, use:
+
+```Bash
+$DC 'markdown-link-check docs/software/big_data_frameworks.md'
+```
+
+To check whether there are links that point to a wrong target, use
+(this may take a while and gives a lot of output because it runs over all files):
+
+```Bash
+$DC 'find docs -type f -name "*.md" | xargs -L1 markdown-link-check'
+```
+
+#### Spell Checker
+
+For spell-checking a single file, , e.g.
+`doc.zih.tu-dresden.de/docs/software/big_data_frameworks.md`, use:
+
+```$DC './util/check-spelling.sh docs/software/big_data_frameworks.md'
+```
+
+For spell-checking all files, use:
+
+```Bash
+$DC ./util/check-spelling.sh
+```
+
+This outputs all words of all files that are unknown to the spell checker.
+To let the spell checker "know" a word, append it to
+`doc.zih.tu-dresden.de/wordlist.aspell`.
