+# This branch contains a vectorized version of `tess-point`!
+
+This is an attempt to 1) make this tool faster by using Python niceties 2) make the API for this tool easier for Python users. Making the tool faster also means we can do calculations on the fly for updating interactive plots.
+
+This is a work in progress! Lots of documentation is missing.
+
+You probably won't be able to install this branch as it is, because the package structure is broken.

+## Missing Functions
+* star_in_fov
+* optics_fp
+* make_az_asym
+* mm_to_pix
+* radec2pix
+
+## Usage
+
+```python
+TESSPoint(1, 1, 1).pix2radec(coords)
+```
+Where coords is an N x 2 array of pixel coordinates. You can get pixel coordinates for the edge easily using the `footprint` function.
