-*I'll add more to this*
+The crux of this is handled by `ffmpeg` which is a powerful library for dealing with movie file encodings.
+
+A problem we face with converting the `.mov` file into a `.gif` is colours. `.gif` files only support 256 colours, while `.mov` files have a lot more colours. Fortunately, for screencasts, but all colours are used, so we can create a palette of most comment colours that are used. And we do this with `pallettegen`. This palette is fed into ffmpeg to construct our `.gif` in almost exact replication to the `.mov` file.

+## Update
+
+In the above shell script, I had to move the files into a speific folder and then run this command. It got extremely cumbersome to have move files around in order to turn them into gifs. I also wanted the option of using a command line tool to turn a selected file into a gif. For examples `makegif test.mov`.
+
+Hence, I started [working on `makegif`](https://github.com/shivan-s/makegif). I decided to use Golang because it's easy to delivery a binary to work as a CLI (command line interface). It's essentially glues together multiple projects:
+
+- [Cobra](https://github.com/spf13/cobra) - helps create CLIs
+- [ffmpeg-go](https://github.com/u2takey/ffmpeg-go) - a wrapper for ffmpeg and palletegen
+
+The package can be installed if the user has Golang installed.
+
+```bash
+go install github.com/shivan-s/makegif
+
+```
+
+Now it can be used as a normal CLI tool. The plan in future is to make this installable via `brew`.
