 ## Description
 This research compendium regroups scripts used to download, re-structure and aggregate data sets to constitute a large meta-analysis of communities sampled at least twice, 10 years apart or more. It is a child project from chase-lab/homogenisation and a brother project to chase-lab/metacommunity-surveys and chase-lab/checklist_change.
 
+## Data
+Raw and aggregated data tables are provided. Aggregated data are in data/communities.csv and data/metadata.csv and column definitions are given in definitions_communities.txt and definitions_metadata.txt.
+
 ## Reproducibility and R environment
-### Installation
 
-After downloading or cloning this repository, run these scripts in order to download raw data, wrangle raw data and merge all data sets into one long table.
+To ensure reproducibility, the working environment (R version and package version) were documented and isolated using the package `renv` (https://rstudio.github.io/renv/index.html). By running `renv::restore()`, `renv` will install all missing packages at once. This function will use the renv.lock file to download the same versions of packages that we used and install them on your system.
