Problem

1. Tab Autocomplete config "Full Example" is not a full example because it does not show the context in which it needs to be defined. Is it an entry in the "models" list or is it an own category?

2. How do I use a local model? The example uses https:// this will not work!

Solution

• Add enough surrounding context to enable users to figure out where the config belongs
• Add also an example showing use of e.g. local ollama
