+# Using `sqlite-vec` in rqlite
+
+[rqlite](https://rqlite.io/) users can use `sqlite-vec` with rqlite by loading the extension when they launch their rqlite node:
+
+```bash
+# Download a sqlite-vec release.
+curl -L https://github.com/asg017/sqlite-vec/releases/download/v0.1.1/sqlite-vec-0.1.1-loadable-linux-x86_64.tar.gz -o sqlite-vec.tar.gz
+
+# Tell rqlite to load sqlite-vec at launch time.
+rqlited -extensions-path=sqlite-vec.tar.gz data
+```
+
+Once loaded you can use sqlite-vec functionality within rqlite. For example, you can perform searches via the [rqlite shell](https://rqlite.io/docs/cli/):
+
+```
+$ rqlite
+Welcome to the rqlite CLI.
+Enter ".help" for usage hints.
