-# ussd
+# URDT USSD service
 
-> USSD
+This is a USSD service built using the [go-vise](https://github.com/nolash/go-vise) engine.
 
-USSD service.
+## Prerequisites
+### 1. [go-vise](https://github.com/nolash/go-vise)
+
+Set up `go-vise` by cloning the repository into a separate directory. The main upstream repository is hosted at: `https://git.defalsify.org/vise.git`
+```
+git clone https://git.defalsify.org/vise.git
+```
+
+## Setup
+1. Clone the ussd repo in its own directory
+
+    ```
+    git clone https://git.grassecon.net/urdt/ussd.git
+    ```
+
+2. Navigate to the project directory.
+3. Enter the `services/registration` subfolder:
+    ```
+    cd services/registration
+    ```
+4. make the .bin files from the .vis files
+    ```
+    make VISE_PATH=/var/path/to/your/go-vise -B
+    ```
+5. Return to the project root (`cd ../..`)
+6. Run the USSD menu 
+    ```
+    go run cmd/main.go -session-id=0712345678
+    ```
+## Running the different binaries
+1. ### CLI: 
+    ```
+    go run cmd/main.go -session-id=0712345678
+    ```
+2. ### Africastalking: 
+    ```
+    go run cmd/africastalking/main.go
+    ```
+3. ### Async: 
+    ```
+    go run cmd/async/main.go
+    ```
+4. ### Http: 
+    ```
+    go run cmd/http/main.go
+    ```
+    
+## Flags
+Below are the supported flags:
+
+1. `-session-id`: 
+    
+    Specifies the session ID. (CLI only). 
+    
+    Default: `075xx2123`.
+
+    Example:
+    ```
+    go run cmd/main.go -session-id=0712345678
+    ```
+
+2. `-d`: 
+
+    Enables engine debug output. 
+    
+    Default: `false`.
+
+    Example:
+    ```
+    go run cmd/main.go -session-id=0712345678 -d
+    ```
+
+3. `-db`: 
+
+    Specifies the database type.
+    
+    Default: `gdbm`.
+
+    Example:
+    ```
+    go run cmd/main.go -session-id=0712345678 -d -db=postgres
+    ```
+
+    >Note: If using `-db=postgres`, ensure PostgreSQL is running with the connection details specified in your `.env` file.
