+
+```lua
+require("gopher").setup({
+  gotests = {
+    template = "testify",
+    named = true
+  }
+})
+```
+
+For named tests to work you have to install gotests from develop branch, for example using [mason-tool-installer](https://github.com/WhoIsSethDaniel/mason-tool-installer.nvim):
+
+```lua
+ require('mason-tool-installer').setup({
+  ensure_installed = {
+    { "gotests", version = "develop" },
+  }
+})
+```
+
+Or by calling `vim.fn.jobstart`:
+
+```lua
+vim.fn.jobstart("go install github.com/cweill/gotests/...@develop")
+```
+
+If you're using `lazy.nvim` you can put in `build` function inside `setup()`
