+If you receive an error associated with github_PAT credentials, you may need to setup a GitHub Personal Access Token (PAT) for authentication when you try to install a package from GitHub using `devtools::install_github()`. Here are the steps to resolve this issue:
+
+1. **Generate a new GitHub PAT**: Go to your GitHub account settings, then to Developer settings -> Personal access tokens -> Generate new token (classic or fine-grained). Set expiration date and save token. Token will disappear if not saved.
+
+2. **Set the new PAT in your R environment**: You can use the `usethis` package to set the PAT in your R environment. Here's how:
+
+```r
+# Install the usethis package if you haven't already
+install.packages("usethis")
+
+# Use usethis to set the GITHUB_PAT environment variable
+usethis::edit_r_environ()
+
+# This will open your .Renviron file in a text editor. Add the following line to the file, replacing "your_new_pat" with your actual PAT:
+GITHUB_PAT=your_new_pat
+
+# Save and close the file. Then, restart your R session to make sure the new environment variable takes effect.
+```
+
+3. **Try installing the package again**: Now, you should be able to install the package from GitHub without encountering the authentication error. Follow steps in Option 1.
