The next (often required) optional configuration option is the location of the Scandit Engine library location (external WebAssembly files): scandit-engine-sdk.min.js and scandit-engine-sdk.wasm. WebAssembly requires these separate files which are loaded by our main library at runtime. They can be found inside the build folder in the library you either download or access via a CDN; if you download the library, these files should be put in a path that's accessible to be downloaded by the running library script. The configuration option that you provide should then point to the folder containing these files, either as a path of your website or an absolute URL (like the CDN one). By default the library will look at the root of your website. If you use the CDN to access the library, you will want to set this to " -sdk/build", " -sdk/build", or similar. Please ensure that the version of the main library that you set up in the "Getting Started" section corresponds to the version of the external Scandit Engine library retrieved via the engineLocation option. This is particularly important if you make use of a CDN: the version pointed at should be in both cases either the latest available one or the same specific one. 2b1af7f3a8
