 In case you lack the C compiler on your Fedora, you can install C development tools group:
 
 ```
-$ sudo dnf group install "C Development Tools and Libraries"
+$ sudo dnf group install c-development
 ```
 
 Other missing header files will depend on the particular gem you want to install. In Fedora the sub-packages containing header files are always suffixed with `-devel` so for example to install the `pg` gem, you will need to compile its C extensions against PostgreSQL header files that can be installed by installing `postgresql-devel` sub-package.

 ## Installing Ruby with rbenv

+The first step is to install dependencies for Ruby and rbenv.

-Then we are going to clone rbenv and the ruby-build rbenv plugin into the home directory.
-To make rbenv command available we append your shell's rc file with initialization.
-
+To use Fedora packaged rbenv also install:
 ```console
-$ git clone https://github.com/rbenv/rbenv.git ~/.rbenv
-$ git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
-$ echo 'eval "$(~/.rbenv/bin/rbenv init -)"' >> ~/.bash_profile
+$ sudo dnf install rbenv ruby-build-rbenv
 ```
 
-Next step we have to refresh the shell to make the binaries available. This can be achieved
-by either the following command or opening a new terminal:
+To use upstream rbenv, follow the steps in [Installing Ruby with
+rbenv](/tech/languages/ruby/ruby-installation.html#installing-ruby-with-rbenv).
+
+Then configure your shell to enable rbenv:
+
 ```console
-$ exec $SHELL -l
+$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
+$ source ~/.bashrc
 ```
 
-Now you can install Ruby simply via `rbenv install`
+Install a Ruby version, such as 3.4.9. See `rbenv install --list` for available versions.
+
 ```console
-$ rbenv install 3.0.4
-$ rbenv global 3.0.4
+$ rbenv install 3.4.9
+$ rbenv global 3.4.9
 $ ruby -v
 ```

 Use this command if you do not want rubygems to install the documentation for each package locally.
 
 ```console
-$ echo "gem: --no-document" > ~/.gemrc
+$ echo "gem: --no-ri --no-rdoc" > ~/.gemrc
 ```
 
+### Rbenv rehash
+
+`rbenv rehash` is not needed when installing gems via `gem install` as rbenv will automatically
+trigger the rehash. You may need to trigger a rehash manually after installing gems using bundler.
+You can do so by running
+```console
+$ rbenv rehash
+```
+
+Since [rbenv commit 325abac](https://github.com/rbenv/rbenv/commit/325abac17de79a230152bb7038126a0641c6aa64),
+there is no need to run `rbenv rehash` when installing gems via bundler or `gem install`.
+Rbenv will automatically trigger the rehash using either of those methods. To ensure you have this
+version installed, follow the [basic git checkout installation instructions](https://github.com/rbenv/rbenv?tab=readme-ov-file#basic-git-checkout).

 Install bundler:
