-# Environment Variables
-
-To use Nix, some environment variables should be set. In particular,
-`PATH` should contain the directories `prefix/bin` and
-`~/.nix-profile/bin`. The first directory contains the Nix tools
-themselves, while `~/.nix-profile` is a symbolic link to the current
-*user environment* (an automatically generated package consisting of
-symlinks to installed packages). The simplest way to set the required
-environment variables is to include the file
-`prefix/etc/profile.d/nix.sh` in your `~/.profile` (or similar), like
-this:
-
-```bash
-source prefix/etc/profile.d/nix.sh
-```
-
-# `NIX_SSL_CERT_FILE`
-
-If you need to specify a custom certificate bundle to account for an
-HTTPS-intercepting man in the middle proxy, you must specify the path to
-the certificate bundle in the environment variable `NIX_SSL_CERT_FILE`.
-
-If you don't specify a `NIX_SSL_CERT_FILE` manually, Nix will install
-and use its own certificate bundle.
-
-Set the environment variable and install Nix
-
-```console
-$ export NIX_SSL_CERT_FILE=/etc/ssl/my-certificate-bundle.crt
-$ curl -L https://nixos.org/nix/install | sh
-```
-
-In the shell profile and rc files (for example, `/etc/bashrc`,
-`/etc/zshrc`), add the following line:
-
-```bash
-export NIX_SSL_CERT_FILE=/etc/ssl/my-certificate-bundle.crt
-```
-
-> **Note**
->
-> You must not add the export and then do the install, as the Nix
-> installer will detect the presence of Nix configuration, and abort.
-
-If you use the Nix daemon, you should also add the following to
-`/etc/nix/nix.conf`:
-
-```
-ssl-cert-file = /etc/ssl/my-certificate-bundle.crt
-```
-
-## Proxy Environment Variables
-
-The Nix installer has special handling for these proxy-related
-environment variables: `http_proxy`, `https_proxy`, `ftp_proxy`,
-`all_proxy`, `no_proxy`, `HTTP_PROXY`, `HTTPS_PROXY`, `FTP_PROXY`,
-`ALL_PROXY`, `NO_PROXY`.
-
-If any of these variables are set when running the Nix installer, then
-the installer will create an override file at
-`/etc/systemd/system/nix-daemon.service.d/override.conf` so `nix-daemon`
-will use them.
