 ## Installation
 
-For releases from August 2022 it is recommended that you [create and use a Github PAT](https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token) to install the latest version of this package. Once you have the PAT, run the following:
-
 ```r
-Sys.setenv(GITHUB_PAT = "your_access_token_here")
-if (!require("remotes")) install.packages("remotes")
-remotes::install_github("insightsengineering/random.cdisc.data@*release")
+install.packages("random.cdisc.data")
 ```
 
-A stable release of all `NEST` packages from June 2022 is also available [here](https://github.com/insightsengineering/depository#readme).
+Alternatively, you might also use the development version.
+
+```r
+# install.packages("pak")
+pak::pak("insightsengineering/random.cdisc.data")
+```
