+### How to find these IDs?
+
+The easiest way is to use planemo to generate the training from a workflow. In recent versions of planemo, this is managed automatically.
+
+The alternative is to figure out the ID for the tool you want to use:
+
+1. Find your tool in Galaxy, and click to access the tool form.
+2. Click on Options at the top right
+3. Click on Share
+4. The URL shown will be something like `https://usegalaxy.eu/root?tool_id=toolshed.g2.bx.psu.edu/repos/galaxyp/mz_to_sqlite/mz_to_sqlite/2.0.4+galaxy1`
+5. Keep only the part after the `=`, so `toolshed.g2.bx.psu.edu/repos/galaxyp/mz_to_sqlite/mz_to_sqlite/2.0.4+galaxy1` in this example
