 The below setup should work for the vast majority of users for common use cases.
-See [Advanced configuration](#advanced-configuration) for details and more configuration options.
+See [Advanced configuration](#advanced-configuration)
+and specifically [Manual shell setup](#manual-shell-setup) for details and more configuration options.
 
-If `pyenv` is already on `PATH`, you can configure the relevant shell startup
-files automatically:
+To add the suggested setup code to the startup files of the running shell,
+run `<path/to/pyenv> --install`.
+Specifically:
+
+* If you installed Pyenv with the installer script:
+
+```sh
+~/.pyenv/bin/pyenv init --install
+```
+
+* If you installed Pyenv with Homebrew:
 
 ```sh
 pyenv init --install
 ```
 
-If `pyenv` is not on `PATH` yet, run the same command through the `pyenv`
-executable in your chosen installation directory.
-
-This uses the same shell detection as `pyenv init`. If a startup file already
-contains Pyenv-related configuration, the command refuses to edit it; review the
-file manually and run `pyenv init <shell>` to see the suggested setup.
-
 For Bash, avoid the automatic `--install` path if your `BASH_ENV` points to
 `.bashrc`; use the manual Bash instructions below so the `eval "$(pyenv init - bash)"`
 line only goes in your login startup file.
 
-#### Bash
-  <details>
-
-  Stock Bash startup files vary widely between distributions in which of them source
-  which, under what circumstances, in what order and what additional configuration they perform.
-  As such, the most reliable way to get Pyenv in all environments is to append Pyenv
-  configuration commands to both `.bashrc` (for interactive shells)
-  and the profile file that Bash would use (for login shells).
-
-  1. First, add the commands to `~/.bashrc` by running the following in your terminal:
-
-      ```bash
-      echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
-      echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
-      echo 'eval "$(pyenv init - bash)"' >> ~/.bashrc
-      ```
-  2. Then, if you have `~/.profile`, `~/.bash_profile` or `~/.bash_login`, add the commands there as well.
-     If you have none of these, create a `~/.profile` and add the commands there.
-
-     * to add to `~/.profile`:
-       ``` bash
-       echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.profile
-       echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.profile
-       echo 'eval "$(pyenv init - bash)"' >> ~/.profile
-       ```
-     * to add to `~/.bash_profile`:
-       ```bash
-       echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
-       echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
-       echo 'eval "$(pyenv init - bash)"' >> ~/.bash_profile
-       ```
-
-   **Bash warning**: There are some systems where the `BASH_ENV` variable is configured
-   to point to `.bashrc`. On such systems, you should almost certainly put the
-   `eval "$(pyenv init - bash)"` line into `.bash_profile`, and **not** into `.bashrc`. Otherwise, you
-   may observe strange behaviour, such as `pyenv` getting into an infinite loop.
-   See [#264](https://github.com/pyenv/pyenv/issues/264) for details.
-   
-   </details>
-   
-#### Zsh
-  
-  <details>
-  Add Pyenv startup commands to `~/.zshrc` by running the following in your terminal:
-  
-  ```zsh
-  echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
-  echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
-  echo 'eval "$(pyenv init - zsh)"' >> ~/.zshrc
-  ```
-  
-  If you wish to get Pyenv in noninteractive login shells as well, also add the commands to `~/.zprofile` or `~/.zlogin`.

-#### Fish
-
-  <details>
-
-  1. If you have Fish 3.2.0 or newer, execute this interactively:
-     ```fish
-     set -Ux PYENV_ROOT $HOME/.pyenv
-     test -d $PYENV_ROOT/bin; and fish_add_path $PYENV_ROOT/bin
-     ```
-
-  2. Otherwise, execute the snippet below:
-     ```fish
-     set -Ux PYENV_ROOT $HOME/.pyenv
-     test -d $PYENV_ROOT/bin; and set -U fish_user_paths $PYENV_ROOT/bin $fish_user_paths
-     ```
-
-  3. Now, add this to `~/.config/fish/config.fish`:
-     ```fish
-     pyenv init - fish | source
-     ```
