+Indeed, there are several ways to take note during experiments, it will depend on the personal habits, on the research field, on the type of projetc (collaborative, personal), etc...
+However, in all the scenarios we are prone to take notes or, more precisely, we **need** to **take notes**. Some are more important than others. Some are even useless. 
 
+I love taking notes. And I lose myself in the hugh amounts of papers where I write them. I'm a paper person (maybe that is why my informatic skills are not so developed...)
+I noted some years ago that my techniques of taking notes are not long lasting, as I am note able to understand them after a few weeks.  Thus, I am used to type  my notes in the computer. 
+Still, it is not  really organised and I need take to remember where I put some data, if they exists... Sometimes our memory invent thinks!
 
+`What I learned in this module:` 
 
+- John Locks technique of indexing : first letter + first vowel of the word. Example: *A*n*a*lyse (Aa)
+- There are other programs and formats to take notes (and write texts) besides **Word** and **Notepad**:  markup language (LML) or langage de balisage
+- **Fichier text:** Un fichier dont le contenu est fait de caractères UTF-8 = garanti perenité et visibilité sur tous les ordinateurs disponibles
+- **Balise (markup):** Un caractère, ou une série de caractères, utilisé pour la structuration d’un document et qui sera invisible par le lecteur final
+- Markdown:langage de balisage léger
+- Pandoc: outils pour convertire un fichier Markdown en un format plus sofistiqué comme PDF et HTML
