-# 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.

+# Internals
+
+## Version
+
+This document describes component versions:
+
+* `urdt-ussd` `v0.5.0-beta`
+* `go-vise` `v0.2.2`
+
+
+## User profile data
+
+All user profile items are stored under keys matching the user's session id, prefixed with the 8-bit value `git.defalsify.org/vise.git/db.DATATYPE_USERDATA` (32), and followed with a 16-big big-endian value subprefix.
+
+For example, given the sessionId `+254123` and the key `git.grassecon.net/urdt-ussd/common.DATA_PUBLIC_KEY` (2) will be stored under the key:
+
+```
+0x322b3235343132330002
+
+prefix   sessionid       subprefix
+32       2b323534313233  0002
+```
+
+### Sub-prefixes
+
+All sub-prefixes are defined as constants in the `git.grassecon.net/urdt-ussd/common` package. The constant names have the prefix `DATA_`
+
+Please refer to inline godoc documentation for the `git.grassecon.net/urdt-ussd/common` package for details on each data item.
