-<p>Reproducibility is a cornerstone of scientific research, and HEP is
-no exception. It ensures that experimental results can be verified
-independently, bolstering the credibility of scientific findings. To
-achieve reproducibility, researchers must provide detailed descriptions

-used. This allows others to replicate the experiments and compare their
-results. Tools like <a href="">REANA</a> and <a href="">Snakemake</a>
-can significantly aid in reproducibility by providing platforms for
-creating, managing, and sharing reproducible computational workflows.
-These tools help researchers document their experimental steps, track
-dependencies, and ensure that results can be replicated consistently,

-<p>Reproducibility is a cornerstone of scientific research, and HEP is

-used. This allows others to replicate the experiments and compare their
-results. Tools like <a href="">REANA</a> and <a href="">Snakemake</a>
-can significantly aid in reproducibility by providing platforms for

+## Reproducibility
+
+Reproducibility is a cornerstone of scientific research, and HEP is no exception.
+It ensures that experimental results can be verified independently, bolstering the credibility of scientific findings.
+To achieve reproducibility, researchers must provide detailed descriptions of their methodologies, including the tools, datasets, and parameters used.
+This allows others to replicate the experiments and compare their results.
+Tools like [REANA]() and [Snakemake]() can significantly aid in reproducibility by providing platforms for creating, managing, and sharing reproducible computational workflows.
+These tools help researchers document their experimental steps, track dependencies, and ensure that results can be replicated consistently, fostering trust in scientific discoveries.
+

+## Who are the first users of a reproducible workflow?
+
+:::::::::::::::::::::: solution
+Me, myself and my group. :grin:
+::::::::::::::::::::::
+::::::::::::::::::::::::::::::::::::::::::::::::::::::
+
+
+This is a lesson created via The Carpentries Workbench. It is written in
+[Pandoc-flavored Markdown](https://pandoc.org/MANUAL.txt) for static files and
+[R Markdown][r-markdown] for dynamic files that can render code into output.
+Please refer to the [Introduction to The Carpentries
+Workbench](https://carpentries.github.io/sandpaper-docs/) for full documentation.
+
+What you need to know is that there are three sections required for a valid
+Carpentries lesson:
+
+ 1. `questions` are displayed at the beginning of the episode to prime the
+    learner for the content.
+ 2. `objectives` are the learning objectives for an episode displayed with
+    the questions.
+ 3. `keypoints` are displayed at the end of the episode to reinforce the
+    objectives.
