+# WSO2 Financial Services Accelerator
+
+Financial Services Accelerator is a collection of technologies that increases the speed and reduces the complexity of adopting open banking compliance.
+
+### Building from the source
+
+If you want to build Financial Services Accelerator from the source code:
+
+1. Install Java8 or above.
+1. Install [Apache Maven 3.0.5](https://maven.apache.org/download.cgi) or above.
+1. Install [MySQL](https://dev.mysql.com/doc/refman/5.5/en/windows-installation.html).
+1. To get the Financial Services Accelerator from [this repository](https://github.com/wso2/financial-services-accelerator.git), click **Clone or download**.
+    * To **clone the solution**, copy the URL and execute the following command in a command prompt.
+      `git clone <the copiedURL>`. After cloning, checkout to the **main** branch.
+    * To **download the pack**, select the branch **main** first, then click **Download ZIP** and unzip the downloaded file.
+1. Navigate to the downloaded solution using a command prompt and run the Maven command.
+
+   |  Command | Description                                                                                                                                                                      |
+               | :--- |:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+   | ```mvn install``` | This starts building the pack without cleaning the folders.                                                                                                                      |
+   | ```mvn clean install``` | This cleans the folders and starts building the solution pack from scratch.                                                                                                      |
+   | ```mvn clean install -P solution``` | This cleans the folders and starts building the solution pack from scratch. Finally creates the accelerator zip files containing the artifacts required to setup the deployment. |
