+* Things that I have learnt
+  * How to create a go file
+    * Step 1: Create a folder `mkdir <folderName>`
+    * Step 2: Go inside that folder & run cmd as `go mod init <domain>/<packageName>`
+    * Step 3: Create a go module by creating a new file `[fileName].go`
+    * Step 4: Write some basic go code in it and to run it type `go run .` or `go run <fileName>`
+
+* [TBD]
