+**Note:** You can also execute the client binary directly via command line in your project:
+
+```shell
+yarn typeform-api <method> [params]
+```
+
+See [next section](#via-command-line) for more details.
+
+### Via command line
+
+1. Clone this repo on your machine
+
+2. Install all dependencies:
+
+```shell
+yarn install
+```
+
+3. Set your personal token as `TF_TOKEN` env variable
+
+```shell
+export TF_TOKEN=tfp_XXXXXXXXXX
+```
+
+4. Run the client:
+
+```shell
+yarn typeform-api <method> [params]
+```
+
+See [reference](#reference) for all available method names and their params.
+
+Example usage:
+
+```shell
+yarn typeform-api forms.list
+yarn typeform-api forms.get '{uid:"abcd1234"}'
+yarn typeform-api themes.list '{pageSize:3}'
+```
