+### ctags vs LSP
+
+`ted` has support for two separate systems for IDE features. `ctags`
+is very lightweight (a ctags installation is just 1.6 MB), and allows
+for go-to-definition and limited autocompletion. This has very low CPU usage,
+and will work just fine on very large projects (for large projects I would
+recommend increasing `tags-max-depth` and turning `regenerate-tags-if-not-found` off).
+
+LSP servers have lots of features but use lots of CPU and memory,
+and may take longer to come up with completions/find definitions, especially
+for large projects. However the LSP server runs in a separate thread, so it will not slow down
+the ordinary text editing features of `ted` (unless the server starts
+using 100% of all CPU cores, which is unlikely).
+
+I would recommend trying out an LSP server if you're unsure about which one to use.
