+# Peter's Musical Notebook
+
+Record audio, compress to Flac & MP3 files, create an index.html with a link to each MP3 and synch the new index and the MP3s to an S3 bucket.
+
+## Pre-requisites
+- Ruby
+- Sox
+- docker
+
+
+## Setup
+1. Create an S3 bucket.
+2. Create a CNAME to point to it.
+
+3. Create a "secrets.env" file and add 
+- your AWS key
+- AWS Secret
+- S3 Bucket name where you want to upload the files
+
+4. Copy the below into a script and run it. Read the comments to understand how it works.
+5. Record some audio. When the audio stops, the script will compress it, generate a new index, and upload the MP3 and the new index to the S3 bucket.
+
+```
+#load secrets into env 
+source secrets.env
+
