-# URDT USSD service
+# ussd
 
-This is a USSD service built using the [go-vise](https://github.com/nolash/go-vise) engine.
+> USSD
 
-## 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.
+USSD service.

-## 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.
