+### Commands
+
+The two installation commands shares similar signatures, something like this:
+
+```bash
+./google-for-testing install:<browser|driver> [options]
+```
+
+There are three options available to change the way the command works.
+
+- **`--ver=[VER]`**:
+This option by default is set to `115.0.5763.0` in both commands.
+    > **Note**:
+    For the `install:driver` command, the default version it's really important, this is the started version from where you can get
+    the `chromedriver` binary, before that version, we don't have access to it (for now).
+
+- **`--latest`**:
+This option will download the latest version.
+
+- **`--path=[PATH]`**:
+This will let you choose where to download it.
+
+> **Note**:
+> The default location for every download is `$HOME/.google-for-testing`
