 ### Installing the plugin
 To install the plugin requires the plugin executable binary as well as the plugin manifest file to be unpacked/copied into
-a Pact plugin directory. By default, this will be `.pact/plugins/protobuf-<version>` in the home directory (i.e. `$HOME/.pact/plugins/protobuf-0.1.3`).
-
-Example installation of Linux version 0.1.3: 
-1. Create the plugin directory if needed: `mkdir -p ~/.pact/plugins/protobuf-0.0.3`
-2. Download the plugin manifest into the directory: `wget https://github.com/pactflow/pact-protobuf-plugin/releases/download/v-0.1.3/pact-plugin.json -O ~/.pact/plugins/protobuf-0.1.3/pact-plugin.json`
-3. Download the plugin executable into the directory: `wget https://github.com/pactflow/pact-protobuf-plugin/releases/download/v-0.1.3/pact-protobuf-plugin-linux-x86_64.gz  -O ~/.pact/plugins/protobuf-0.1.3/pact-protobuf-plugin-linux-x86_64.gz`
-4. Unpack the plugin executable: `gunzip -N ~/.pact/plugins/protobuf-0.1.3/pact-protobuf-plugin-linux-x86_64.gz`
+a Pact plugin directory. By default, this will be `.pact/plugins/protobuf-<version>` in the home directory (i.e. `$HOME/.pact/plugins/protobuf-0.1.5`).
+
+Example installation of Linux version 0.1.3 (replace with the actual version you are using): 
+1. Create the plugin directory if needed: `mkdir -p ~/.pact/plugins/protobuf-0.1.5`
+2. Download the plugin manifest into the directory: `wget https://github.com/pactflow/pact-protobuf-plugin/releases/download/v-0.1.5/pact-plugin.json -O ~/.pact/plugins/protobuf-0.1.3/pact-plugin.json`
+3. Download the plugin executable into the directory: `wget https://github.com/pactflow/pact-protobuf-plugin/releases/download/v-0.1.5/pact-protobuf-plugin-linux-x86_64.gz  -O ~/.pact/plugins/protobuf-0.1.5/pact-protobuf-plugin.gz`
+4. Unpack the plugin executable: `gunzip -N ~/.pact/plugins/protobuf-0.1.5/pact-protobuf-plugin.gz`
+5. Make the plugin executable: `chmod +x ~/.pact/plugins/protobuf-0.1.5/pact-protobuf-plugin`
 
 **Note:** The unpacked executable name must match the `entryPoint` value in the manifest file. By default, this is
 `pact-protobuf-plugin` on unix* and `pact-protobuf-plugin.exe` on Windows.
