-### COMPOSER_ROOT_VERSION
+### COMPOSER_ALLOW_SUPERUSER
 
-By setting this var you can specify the version of the root package, if it can
-not be guessed from VCS info and is not present in `composer.json`.
+If set to 1, this env disables the warning about running commands as root/super user.
+It also disables automatic clearing of sudo sessions, so you should really only set this
+if you use Composer as super user at all times like in docker containers.
 
-### COMPOSER_VENDOR_DIR
+### COMPOSER_AUTH
 
-By setting this var you can make Composer install the dependencies into a
-directory other than `vendor`.
+The `COMPOSER_AUTH` var allows you to set up authentication as an environment variable.
+The contents of the variable should be a JSON formatted object containing http-basic,
+github-oauth, bitbucket-oauth, ... objects as needed, and following the
+[spec from the config](06-config.md#gitlab-oauth).
 
 ### COMPOSER_BIN_DIR
 
 By setting this option you can change the `bin` ([Vendor Binaries](articles/vendor-binaries.md))
 directory to something other than `vendor/bin`.
 
-### http_proxy or HTTP_PROXY
-
-If you are using Composer from behind an HTTP proxy, you can use the standard
-`http_proxy` or `HTTP_PROXY` env vars. Simply set it to the URL of your proxy.
-Many operating systems already set this variable for you.
-
-Using `http_proxy` (lowercased) or even defining both might be preferable since
-some tools like git or curl will only use the lower-cased `http_proxy` version.
-Alternatively you can also define the git proxy using
-`git config --global http.proxy <proxy url>`.
-
-If you are using Composer in a non-CLI context (i.e. integration into a CMS or
-similar use case), and need to support proxies, please provide the `CGI_HTTP_PROXY`
-environment variable instead. See [httpoxy.org](https://httpoxy.org/) for further
-details.
-
-### no_proxy or NO_PROXY
+### COMPOSER_CACHE_DIR
 
-If you are behind a proxy and would like to disable it for certain domains, you
-can use the `no_proxy` or `NO_PROXY` env var. Simply set it to a comma separated list of
-domains the proxy should *not* be used for.
+The `COMPOSER_CACHE_DIR` var allows you to change the Composer cache directory,
+which is also configurable via the [`cache-dir`](06-config.md#cache-dir) option.
 
-The env var accepts domains, IP addresses, and IP address blocks in CIDR
-notation. You can restrict the filter to a particular port (e.g. `:80`). You
-can also set it to `*` to ignore the proxy for all HTTP requests.
+By default it points to `$COMPOSER_HOME/cache` on \*nix and macOS, and
+`C:\Users\<user>\AppData\Local\Composer` (or `%LOCALAPPDATA%/Composer`) on Windows.
 
-### HTTP_PROXY_REQUEST_FULLURI
+### COMPOSER_CAFILE
 
-If you use a proxy but it does not support the request_fulluri flag, then you
-should set this env var to `false` or `0` to prevent Composer from setting the
-request_fulluri option.
+By setting this environmental value, you can set a path to a certificate bundle
+file to be used during SSL/TLS peer verification.
 
-### HTTPS_PROXY_REQUEST_FULLURI
+### COMPOSER_DISCARD_CHANGES
 
-If you use a proxy but it does not support the request_fulluri flag for HTTPS
-requests, then you should set this env var to `false` or `0` to prevent Composer
