+The official

+tool is recommended. Install with:
+```bash
+$ pip3 install mpremote
+```
+There are several options for installation
+ 1. Using mpremote to run the GUI demos via the PC without installing.
+ 2. Subtractive. Installing the entire GUI, then (optionally) removing unused
+ components.
+ 3. Additive. Installing a minimal subset and manually adding extra components.
+ 4. Using frozen bytecode.

+The last part of the addresss (`st7789`) is the name of the directory holding

+Install using mpremote on the PC as follows:
+```bash
+$ mpremote mip install "github:peterhinch/micropython-nano-gui/drivers/st7789"
+```
+### Full installation (subtractive)
+
+The entire GUI is large. It is possible to install it all from the PC clone by
+issuing:
+```bash
+$ cd micropython-micro-gui
+$ mpremote cp -r gui :
+$ mpremote cp hardware_setup.py :
+```
+This is rather profligate with Flash storage. There is great scope for
+discarding unused fonts, demos and widgets. As an alternative to installing
+everything and pruning, an additive approach may be used where a minimal subset
+is installed with extra fonts and widgets being added as required.
+
+### Minimal installation (additive)
+
+This installs a subset adequate to run the `simple.py` demo. It comprises:

+It is installed with (on the device):
+```python

+```
+or (on the PC):
+```bash
+$ mpremote mip install "github:peterhinch/micropython-micro-gui"
+```
+In both cases the edited `hardware_setup.py` must be copied from the PC:
+```bash
+$ cd micropython-micro-gui
+$ mpremote cp hardware_setup.py :
+```
+When adding components the directory structure must be maintained. For example,
+in the `micropython-micro-gui` directory:
+```bash
+$ mpremote cp gui/fonts/font10.py :/gui/fonts/
+$ mpremote cp gui/widgets/checkbox.py :/gui/widgets/
+```

+### Freezing bytecode
 
 There is scope for speeding loading and saving RAM by using frozen bytecode.
 The entire `gui` tree may be frozen but the directory structure must be
