+### Telescope
+
+You can easily open any search results in **Trouble**, by defining a custom action:
+
+```lua
+local actions = require("telescope.actions")
+local trouble = require("trouble.providers.telescope")
+
+local telescope = require("telescope")
+
+telescope.setup {
+  defaults = {
+    mappings = {
+      i = { ["<c-t>"] = trouble.open_with_trouble },
+      n = { ["<c-t>"] = trouble.open_with_trouble },
+    },
+  },
+}
+```
+
+When you open telescope, you can now hit `<c-t>` to open the results in **Trouble**
