244244245245+## Installing Racket
246246+247247+The standard way to install Racket is via the official installer script at
248248+<https://racket-lang.org>. Do NOT use `apt-get install racket` or similar
249249+package manager commands — these often install outdated versions from distro
250250+repositories.
251251+252252+### Recommended: Official installer script
253253+254254+```sh
255255+# Download and run the official installer script
256256+curl -Ls https://mirror.racket-lang.org/installers/current/racket-current-x86_64-linux-cs.sh \
257257+ | sh -s -- --in-place --dest ~/racket
258258+export PATH="$HOME/racket/bin:$PATH"
259259+```
260260+261261+Or visit <https://download.racket-lang.org/> to download the installer for your
262262+platform (macOS `.dmg`, Windows `.exe`, or Linux `.sh`).
263263+264264+### macOS
265265+266266+On macOS, drag the downloaded `.app` into `/Applications`, then add the binaries
267267+to your path:
268268+269269+```sh
270270+export PATH="/Applications/Racket v9.0/bin:$PATH"
271271+```
272272+273273+The exact path varies by version number — adjust accordingly.
274274+275275+### Verifying installation
276276+277277+```sh
278278+racket --version # e.g. "Welcome to Racket v9.0 [cs]."
279279+raco --version # should print the same version
