+# Planet CDOT Feed List migration tool
+
+This tool downloads all users from the wiki page and dumps them into a JSON file.
+
+## Customization
+
+In `migrage.js` you can find the following two variables: `FEED_URL` and `FILE_NAME`.
+
+- `FEED_URL` points to the current location of the [Planet CDOT Feed List](https://wiki.cdot.senecacollege.ca/wiki/Planet_CDOT_Feed_List#Feeds)
+- `FILE_NAME` allows users to specify the desired filename of the output file
+
+## Install Dependencies
+
+```
+cd src/tools/migrate
+npm install
+```
+
+## Usage
+
+```
+cd src/tools/migrate
