 If everything works you are good to go.
 
+### Add aliases for all patterns
+In order to add aliases for all your patterns and use them directly as commands ie. `summarize` instead of `fabric --pattern summarize`
+You can add the following to your `.zshrc` or `.bashrc` file.
+
+```bash
+# Loop through all files in the ~/.config/fabric/patterns directory
+for pattern_file in $HOME/.config/fabric/patterns/*; do
+    # Get the base name of the file (i.e., remove the directory path)
+    pattern_name=$(basename "$pattern_file")
+    
+    # Create an alias in the form: alias pattern_name="fabric --pattern pattern_name"
+    alias_command="alias $pattern_name='fabric --pattern $pattern_name'"
+    
+    # Evaluate the alias command to add it to the current shell
+    eval "$alias_command"
+done
+
+yt() {
+    local video_link="$1"
+    fabric -y "$video_link" --transcript
+}
+```
+This also creates a `yt` alias that allows you to use `yt https://www.youtube.com/watch?v=4b0iet22VIk` to get your transcripts.
+
+#### Save your files in markdown using aliases
+If in addition to the above aliases you would like to have the option to save the output to your favourite markdown note vault like Obsidian then instead of the above add the following to your `.zshrc` or `.bashrc` file:
+
+```bash
+# Define the base directory for Obsidian notes
+obsidian_base="/path/to/obsidian"
+
+# Loop through all files in the ~/.config/fabric/patterns directory
+for pattern_file in ~/.config/fabric/patterns/*; do
+    # Get the base name of the file (i.e., remove the directory path)
+    pattern_name=$(basename "$pattern_file")
+
+    # Define a function dynamically for each pattern
+    eval "
+    $pattern_name() {
+        local title=\$1
+        local date_stamp=\$(date +'%Y-%m-%d')
+        local output_path=\"\$obsidian_base/\${date_stamp}-\${title}.md\"
+
+        # Check if a title was provided
+        if [ -n \"\$title\" ]; then
+            # If a title is provided, use the output path
+            fabric --pattern \"$pattern_name\" -o \"\$output_path\"
+        else
+            # If no title is provided, use --stream
+            fabric --pattern \"$pattern_name\" --stream
+        fi
+    }
+    "
+done
+
+yt() {
+    local video_link="$1"
+    fabric -y "$video_link" --transcript
+}
+```
+
+This will allow you to use the patterns as aliases like in the above for example `summarize` instead of `fabric --pattern summarize --stream`, however if you pass in an extra argument like this `summarize "my_article_title"` your output will be saved in the destination that you set in `obsidian_base="/path/to/obsidian"` in the following format `YYYY-MM-DD-my_article_title.md` where the date gets autogenerated for you. 
+You can tweak the date format by tweaking the `date_stamp` format.

You will carefully analyze each prompt to identify the specific requirements, materials, ingredients, or any other necessary components for the tutorial. You will then organize these elements into a structured format, ensuring clarity and ease of understanding for the user.  Your role is to provide comprehensive instructions that guide the user through each step of the DIY process. You will pay close attention to formatting and presentation, making sure the tutorial is accessible and engaging.
+
+Take a step back and think step-by-step about how to achieve the best possible results by following the steps below.

+- Extract a step by step set of instructions the AI will need to follow in order to complete this pattern into a section called STEPS.
+
+- Analyze the prompt to determine what format the output should be in.

+Description
+As a Highlight developer
+I want to migrate email templates over to Mustache
+So that future upgrades to the messenger service can be made easier
+
+Acceptance Criteria
+- Migrate the existing alerting email templates from the instance specific databases over to the messenger templates blob storage.
+	- Rename each template to a GUID and store in it's own folder within the blob storage
+	- Store Subject and Body as separate blobs
+
+- Create an upgrade script to change the value of the Alerting.Email.Template local parameter in all systems to the new template names.
+- Change the template retrieval and saving for user editing to contact the blob storage rather than the database
+- Remove the database tables and code that handles the SQL based templates
+- Highlight sends the template name and the details of the body to the Email queue in Service bus  
+	- this is handled by the generic Email Client (if created already)
+	- This email type will be added to the list of email types that are sent to the messenger service (switch to be removed once all email templates are completed)  
+
+- Include domain details as part of payload sent to the messenger service
+
+Note: ensure that Ops know when this work is being done so they are aware of any changes to existing templates
