+# Installing Binary Distribution of Ivette
+
+You shall have an installed Frama-C binary.
+
+**Warning:** if you already have an `ivette` script along with `frama-c`, this
+script is used for bootstrapping the installation of Ivette from source through
+your internet connection.  The instructions provided here are intended to
+_replace_ this installation procedure from source. Hence, it is highly
+recommanded for you to remove this bootstrapping `ivette` script if you want to
+use the binary distribution of Ivette.
+
+## Ivette for Linux
+
+Download the binary distribution (x86 only for now).
+
+Install it wherever you want and make it executable:
+
+```sh
+cp frama-c-ivette-linux-27.0-Cobalt.AppImage <IVETTE-INSTALL-PATH>/ivette.AppImage
+chmod a+x <IVETTE-INSTALL-PATH>/ivette.AppImage
+```
+
+Then add an alias `ivette` that just runs the AppImage:
+
+```sh
+alias ivette=<ABSOLUTE-IVETTE-INSTALL-PATH>/ivette.AppImage
+```
+
+## Ivette for macOS
+
+Download the suitable binary distribution of `Ivette.app` (x86 or arm64).
+
+You can install Ivette binaries at any location, typically
+`/Applications/Ivette.app` or `~/mylib/Ivette.app`.  To launch Ivette from the
+command line, you will need your own `ivette` script, like the
+following one:
+
+```sh
+#! /usr/bin/env sh
+exec open -na <IVETTE-INSTALL>/Ivette.app --args\
+  --command <FRAMAC-INSTALL>/frama-c\
+  --working $PWD $*
+```
+
+Simply replace `<IVETTE-INSTALL>` and `<FRAMAC-INSTALL>` in the code above with
+the (absolute) paths to your `Ivette.app` and `frama-c` binaries,
+respectively. Then, make your `ivette` script executable and simply use it like
+a `frama-c` command-line binary!
