 You are going to build a pipeline for you or your team. So the first step is to create your own project.
 
+## Forking
+
 Instead of reinventing the wheel, you can use the [pipelines/nextflow](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow) as a template.
 To easily do so, go to the [pipelines/nextflow](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow) repository and click on the [**fork**](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/forks/new) button.

+## Project organisation
+
+This project (and yours) follow the [guide of good practices for the LBMC](http://www.ens-lyon.fr/LBMC/intranet/services-communs/pole-bioinformatique/ressources/good_practice_LBMC)
+
+You are now on the main page of your fork of the [pipelines/nextflow](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow). You can explore this project, all the code in it is under the CeCILL lience (in the [LICENCE](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/blob/master/LICENSE) file).
+
+The [README.md](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/blob/master/README.md) file contains instructions to run your pipeline and test it's installation.
+
+The [CONTRIBUTING.md](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/blob/master/CONTRIBUTING.md) file contains guidelines to follow if you want to contribute to the [pipelines/nextflow](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow) (making a merge request for example).
+
+The [data](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/tree/master/data) folder will be the place were you store the raw data for your analysis.
+The [results](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/tree/master/results) folder will be the place were you store the results of your analysis.
+Note that the content of these two folders should never be saved on git.
+
+The [doc](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/tree/master/doc) folder contains the documentation of this practical course.
+
+And most interestingly for you, the [src](https://gitlab.biologie.ens-lyon.fr/pipelines/nextflow/tree/master/src) contains code to wrapp tools. This folder contains two subdirectory. A `nf_modules` and a `sge_modules` folder.
