<@U017FJJJ8P2> (<@U016EM8L91B>): you can install the whole pdk by running the following sequence:
```make skywater-pdk
make all-skywater-libraries
make open_pdks
make build-pdk```
I think I should group them all in a single Make target and document that.

Also, you can change the default installed skywater std library by exporting a different `STD_CELL_LIBRARY`, default is `sky130_fd_sc_hd` I should document that as well.

<@U01634FSETZ> all-skywater-libraries does not appear to be a valid target. Did you mean make skywater-libraries?

```cd /home/jcyr/openlane/pdks/open_pdks &amp;&amp; \
        git checkout -qf 3959de867a4acb6867df376dac495e33bb0734f1
fatal: reference is not a tree: 3959de867a4acb6867df376dac495e33bb0734f1```


So I deleted the checkout, is HEAD code ok?

That's odd.  That's the right commit number for open_pdks version 1.0.78.

So maybe something is wrong in the .git/config file in openlane/pdks/open_pdks/?

<@U016EM8L91B> Yeah, but you'd need to add the --branch option to the clone command for that checkout to work!
```git clone --branch open_pdks-1.0 <https://github.com/RTimothyEdwards/open_pdks.git> $(PDK_ROOT)/op
en_pdks```
