+## Running AnyCable-Go locally
+
+There are plenty of ways of installing `anycable-go` binary on your machine (see [../anycable-go/getting_started.md]). For your convinience, we also provide an NPM package that can be used to install and run `anycable-go`:
+
+```sh
+npm install --save-dev @anycable/anycable-go
+pnpm install --save-dev @anycable/anycable-go
+yarn add --dev @anycable/anycable-go
+
+# and run as follows
+npx anycable-go
+```
+
+**NOTE:** The version of the NPM package is the same as the version of the AnyCable-Go binary (which is downloaded automatically on the first run).
