-## Secrets
+### Inputs
+
+These are some of the supported input parameters of action.
 
 - `host` - **_(Required)_** this is the SonarQube server URL.
 - `login` - **_(Required)_** the login or authentication token of a SonarQube user with Execute Analysis permission on the project. See [how to generate SonarQube token](https://docs.sonarqube.org/latest/user-guide/user-token/).
 - `password` - The password that goes with the `login` username. This should be left blank if an `login` are authentication token.
+- `projectBaseDir` - Set custom project base directory analysis.
+- `projectKey` - The project's unique key _(allowed characters are: letters, numbers, `-`, `_`, `.` and `:`, with at least one non-digit)_.
+- `projectName` - Name of the project that will be displayed on the SonarQube web interface.
+- `projectVersion` - The project version.
+- `encoding` - Encoding of the source code. Default is UTF-8.
 
-You can set all variable in the "Secrets" settings page of your repository.
+> **Note**:
+> If you're thinking of setting project metadata & other related things in a **`sonar-project.properties`** configuration file _(must be declared in the base directory `projectBaseDir`)_ instead of going through the [input parameters](#inputs), this action supports that!
