 #### Some notes on CI
 
 The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.

 ```
 
-Please if you find any issues using any of the above expressions or syntax
+## Tags
+
+Tags are used to give a name (tag) to a specific path.
+
+### Tag Declaration
+
+The syntax for declaring a tag is `$myTag` you would use it in the following
+way:
+
+```
+startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+```
+
+### Tag Identifier
+
+As per the example above you can use the tag identifier to get a reference to the 
+tagged object. The syntax for this is `myTag`.
+
+In the example above we use the tag identifier to get the angle of the segment
+`segAng(rectangleSegmentA001, %)`.
+
+
+### Tag Scope
+
+Tags are scoped globally if in the root context meaning in this example you can 
+use the tag `rectangleSegmentA001` in any function or expression in the file.
+
+However if the code was written like this:
+
+```
+fn rect = (origin) => {
+  return startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+}
+
+rect([0, 0])
+rect([20, 0])
+``` 
+
+Those tags would only be available in the `rect` function and not globally.
+
+However you likely want to use those tags somewhere outside the `rect` function.
+
+Tags are accessible through the sketch group they are declared in.
+For example the following code works.
+
+```
+fn rect = (origin) => {
+  return startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+}
+
+rect([0, 0])
+const myRect = rect([20, 0])
+
+myRect 
+  |> extrude(10, %)
+  |> fillet({radius: 0.5, tags: [myRect.tags.rectangleSegmentA001]}, %)
+```
+
+See how we use the tag `rectangleSegmentA001` in the `fillet` function outside
+the `rect` function. This is because the `rect` function is returning the
+sketch group that contains the tags.
+
