+### Tailwind intellisense
+
+Tailwind's language server allows you to specify custom configuration on what it should match to start giving you tailwind intellisense.
+
+
+![](/public/tailwind-intellisense.png)
+
+To make this work, you will need to update the tailwind lsp config with the config below:
+
+Main thing to note here is
+1. "go" is added to the includeLanguages list
+2. classRegex is updated to match the tailwind classes in the go code.
+
+### Jetbrains IDE's (GoLand)
+```json
+{
+  "includeLanguages": {
+    "go": "html"
+  },
+  "experimental": {
+    "configFile": null,
+    "classRegex": [
+      ["Class\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"],
+      ["ClassX\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"],
+      ["ClassIf\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"],
+      ["Classes\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"]
+    ]
+  }
+}
+```
+To find this configuration in GoLand you can go to `Settings -> Languages & Frameworks -> Style Sheets -> Tailwind CSS` and update the configuration there.
+These changes are additive, add these options to your existing tailwind lsp config, instead of replacing the entire file.
+
+See more: https://github.com/tailwindlabs/tailwindcss/issues/7553#issuecomment-735915659
+
+<br>
+
+### Visual Studio Code
+For VSCode, you should be able to update your settings.json with the following values:
+
+```json
+{
+  "tailwindCSS.includeLanguages": {
+    "go": "html"
+  },
+  "tailwindCSS.experimental.classRegex": [
+    ["Class\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"],
+    ["ClassX\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"],
+    ["ClassIf\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`]"],
+    ["Classes\\(([^)]*)\\)", "[\"`]([^\"`]*)[\"`"]
+  ]
+}
+```
