+## Setting up Python in R Studio
+The installation instructions provide here correspond to the *01-R_PythonSetup.Rmd* script, and use the [reticulate](https://rstudio.github.io/reticulate/) package and [Miniconda](https://docs.conda.io/en/latest/miniconda.html) to access Python in R Studio.
+
+Install and load the *reticulate* package and *Miniconda*. For novice Python users, we recommend installing Miniconda—a small version of anaconda that includes conda, Python, their dependencies, and common functions—via the `install_miniconda` function from the *reticulate* package. It is important to install *Miniconda* in a separate code chunk after the *reticulate* package has been loaded. 
+
+Identify and set the preferred Python version. We suggest using the `py_discover_config` and `conda_list` functions to identify all possible Python and conda version available, of which the newly installed *Miniconda* should be listed. After that, we recommend setting python from *Miniconda* as the preferred version, which can be done using the `edit_r_profile` function from the *usethis* package. Running `edit_r_profile()` will open a .Rprofile file in a new window where the path to the preferred python version can be set. To do so, change PATH in `Sys.setenv(RETICULATE_PYTHON = “PATH”)` to match the location where *Miniconda* is installed. This path information can be copied and pasted from the output of `conda_list(conda= "auto")`. The correct path will be listed next to the “r-reticulate” option. Save the edited .Rprofile file and restart R so that the changes take effect.
+
+This procedure only needs to be executed once and will be saved for subsequent use. To ensure that the correct environment is being called, we recommend setting the `use_virtualenv` function to “r-reticulate”. The last step is to install python packages using the `py_install` function.
