 ## 2. Installing the package
 
-Please run `remotes::install_github("facebookexperimental/Robyn/R")` to install the package. If you haven't installed the `remotes` package previously, run `install.packages('remotes')`first.
+To install or update Robyn to the latest stable version of the package, run:
+```
+install.packages("Robyn")
+```
 
-Robyn requires the Python library [Nevergrad](https://facebookresearch.github.io/nevergrad/).
-You must install it once for the code to work properly.
-Please find [here](https://rstudio.github.io/reticulate/articles/python_packages.html) more info about installing Python packages via reticulate.
+**NOTE**: If you're interested in installing the latest or a specific **dev version** instead, run `remotes::install_github("facebookexperimental/Robyn/R")`. If you haven't installed the `remotes` package previously, run `install.packages('remotes')` first.
 
-1. First step is to install the [reticulate package](https://rstudio.github.io/reticulate/) via the following command: `install.packages(‘reticulate’)`
-2. Load the package using: `library(reticulate)`
-3. Install nevergrad. You have 2 options:

+2. Install `nevergrad` Python library. You have 2 options:
 
-- **Option 1: nevergrad installation via PIP**
+- **Option 1: using PIP**
 
 ```
 virtualenv_create("r-reticulate")
 py_install("nevergrad", pip = TRUE)
 use_virtualenv("r-reticulate", required = TRUE)
 ```
 
-- **Option 2: nevergrad installation via conda**
+- **Option 2: using conda**
 
 ```
-conda_create("r-reticulate") # must run this line once
-conda_install("r-reticulate", "nevergrad", pip=TRUE)
+conda_create("r-reticulate")
+conda_install("r-reticulate", "nevergrad", pip = TRUE)
 use_condaenv("r-reticulate")
 ```
 
-If it's taking too long to download, you have a slow or unstable internet connection, and have issues while installing the package, try setting `options(timeout=400)`
-
 In case nevergrad still cannot be imported after installation, please locate your python file and run this line using your path:
 ```
 use_python("~/Library/r-miniconda/envs/r-reticulate/bin/python")
 ```
-For Windows, if you get openssl error, please see instructions [here](https://stackoverflow.com/questions/54558389/how-to-solve-this-error-while-installing-python-packages-in-rstudio/54566647) and [here](https://dev.to/danilovieira/installing-openssl-on-windows-and-adding-to-path-3mbf) to install and update openssl.
