+# Twitter Bot
+
+This is a small and very simple twitter bot, which retweets based on search queries.
+
+## How to run this bot
+
+Add a `settings.yaml` file, same structure as `settings.example.yaml` and add your API Tokens etc. plus the search strings you want to retweet.
+
+When done, you can run it by doing:
+
+```shell
+$ go run tweetbot.go
+```
+
+You can also compile a binary, depending on where it has to run
+
+```shell 
+$ go build tweetbot.go
+```
+
+or if you want it to run on you raspberry pi.
+
+```shell 
+env GOOS=linux GOARCH=arm GOARM=5 go build tweetbot.go
+```
+
+## Credits
+
+Thanks to [Miloskrca](https://github.com/miloskrca) for helping with the initial development and for introducing me to Golang.
