go to the WebLicht web interface and click the Start WebLicht button. You'll be prompted to log in to WebLicht via the CLARIN Service Provider Federation. If your home organisation is not in the list, you can request a CLARIN account.

once logged in, create a tool chain, preferably using some of your own data, and run the tools to check the results

click the Download button to save the tool chain configuration. The file will have a name like chain_randomnumber_.xml, it might be practical to rename it to something more intuitive, especially if you plan to have more than one tool chain

make sure to make a note of the type of input of the first tool in the chain, it should be Plain Text or TCF

to be able to run the tool chain from within ELAN, you'll need to generate a so-called API Key. ELAN will run the tool chain via WebLicht as a Service (WaaS), and that service requires an API key to authenticate the request. The API key can be generated on the WaaS home page and then stored locally. The key will be valid for 3 months, after that a new key will have to be generated.

in the third step of running WebLicht in ELAN, all this information has to be provided: the tool chain file, the type of input and the API key (see Figure 303, “WebLicht service: select the tool chain file and paste the access key”)
