1# Configuration File<a name="EN-US_TOPIC_0000001120666799"></a> 2 3The SDK identifies the plug-in type based on **algorithmVersion** and **algorithmType** in the **AlgorithmInfo** structure so it can call the plug-in capabilities. Therefore, you need to develop the plug-in configuration file as follows: 4 51. Add the plug-in configuration file to the **//foundation/ai/engine/services/common/protocol/plugin\_config/plugin\_config\_ini/** directory. 62. Add the algorithm type to the **aie\_algorithm\_type.h** file in the **//foundation/ai/engine/services/common/protocol/plugin\_config/** directory. 73. Add the name of the KWS algorithm and its sequence number in **ALGORITHM\_TYPE\_ID\_LITS** to the **aie\_plugin\_info.h** file in the **//foundation/ai/engine/services/server/plugin\_manager/include/** directory. 8 9For details about the development process, see the development example for the KWS configuration file. 10 11
