+### Building the Debian package
+
+If the `.deb` file provided on the release page uses a `libc` version higher
+than that used by your Debian, Ubuntu, or Mint system, you can build the package
+from source to match your system's dependencies.
+
+Install `cargo-deb`, the tool used for building the `.deb` file:
+
+```sh
+cargo install cargo-deb
+```
+
+After cloning and entering the Helix repository as previously described,
+use the following command to build the release binary and package it into a `.deb` file in a single step.
+
+```sh
+cargo deb -- --locked
+```
+
+> 💡 This locks you into the `--release` profile. But you can also build helix in any way you like.
+> As long as you leave a `target/release/hx` file, it will get packaged with `cargo deb --no-build` 
+
+> 💡 Don't worry about the repeated
