+## ❓  FAQ
+
+<details>
+<summary>
+Why does rig create a user package library?
+</summary>
+
+> Installing non-base packages into a user package library has several
+> benefits:
+>
+> -   The system library is not writeable for regular users on some
+>     systems (Windows and Linux, typically), so we might as well create
+>     a properly versioned user library at the default place.
+> -   Some tools need a clean R environment, with base packages only,
+>     and do not work well if user packages are installed into the
+>     system library. E.g. `R CMD check` is such a tool, and
+>     <https://github.com/r-lib/revdepcheck> is another.
+> -   You can delete an R installation (e.g. with `rig rm`) and then and
+>     then install it again, without losing your R packages.
+
+</details>
+<details>
+<summary>
+Why does rig install pak?
+</summary>
+
+> To be able to install R packages efficiently, from CRAN, Bioconductor
+> or GitHub, right from the start. pak also supports installing system
+> libraries automatically on some Linux systems.
+>
+> If you don’t want `rig add` to install pak, use the `--without-pak`
+> option.
+
+</details>
+<details>
+<summary>
+Why does rig change the permissions of the system library (on macOS)?
+</summary>
+
+> To make sure that you don’t install packages accidentally into the
+> system library. See “Why does rig create a user package library?”
+> above.
+
+</details>
+<details>
+<summary>
+Why does rig set the default CRAN mirror?
+</summary>
+
+> To avoid the extra work the users need to spend on this.
+>
+> The <https://cloud.r-project.org> mirror is usually better than the
+> other, in that it is a CDN that is close to most users, and that it is
+> updated more often.
+>
+> If you want to use a different mirror, you can set the `repos` option
+> in your `.Rprofile`, so the rig repo settings will be ignored.
+>
+> You can also use the `--without-cran-mirror` option of `rig add`.
+
+</details>
+<details>
+<summary>
+Why does rig set up RSPM?
+</summary>
+
+> RSPM ([Rstudio Package
+> Manager](https://packagemanager.rstudio.com/client/#/)) is generally
+> superior to a refular CRAN mirror on Windows and many Linux systems.
+>
+> On Linux it includes binary packages for many popular distributions.
+>
+> On Windows, it includes up to date binary packages for older R
+> versions as well.
+>
+> To avoid RSPM, use the `--without-rspm` option of `rig add`.
+
+</details>
+<details>
+<summary>
+Can rig install R without admin permissions
+</summary>
+
+> No, currently it cannot.
+
+</details>
+<details>
+<summary>
+How is rig different from RSwitch?
+</summary>
+
+> While there is a small overlap in functionality, rig and
+> [RSwitch](https://rud.is/rswitch/) are very different. I suggest you
+> look over the features of both to decide which one suits your needs
+> better.
+>
+> If you like rig and also like the extra features of RSwitch, then you
+> can use them together just fine: changing the default R version in
+> RSwitch also changes it in rig and vice versa. You can use the rig cli
+> and the RSwitch app together, or you can also use both menu bar apps
+> at the same time.
