+## Installation
+
+You can conveniently install chents from the repository kindly made available by the
+R-Universe project:
+
+```
+install.packages("chents",
+  repos = c("https://jranke.r-universe.dev", "https://cran.r-project.org"))
+```
+
+In order to profit from the chemoinformatics, you need to install RDKit and its
+python bindings. On a Debian type Linux distribution, just use
+
+```
+sudo apt install python3-rdkit
+```
+If you use this package on Windows or MacOS, I would be happy to include
+installation instructions here if you share them with me, e.g. via a Pull
+Request.
+
+## Configuration of the Python version to use
+
+On Debian type Linux distributions, you can use the following line in your
+global or project specific `.Rprofile` file to tell the `reticulate` package to
+use the system Python version that will find the RDKit installed in the system
+location.
+
+```
+Sys.setenv(RETICULATE_PYTHON="/usr/bin/python3")
+```
+
