+# Instamark
+Converts an Instapaper CSV export of bookmarks into the Netscape Bookmark file format.
+
+## Usage
+Login to your Instapaper account on a desktop computer (the CSV export functionality isn't available
+on mobile). Click your username in the top-right hand corner of the screen, then select settings.
+Select "Download .CSV file" in the Export section at the bottom of the page. Navigate to the location
+the export was saved to in a terminal window and then run:
+
+```shell
+instamark instapaper-export.csv > instapaper-bookmarks.html
+```
+
+You exported Instapaper data is now saved in the `instapaper-bookmarks.html` file, which you can
+import into Safari, Chrome, Firefox, or any other browser which supports the Netscape bookmark file
+format.
+
+## Installation
+This GitHub repository contains executable binaries for Linux and macOS in the Release
+section for download.
+
+Additionally, download the source code from this repository, navigate to the root directory, and run
+```shell
+cargo build --release
+```
