 # skywater130_decred_miner
 
+# Environment setup
+Follow the steps at https://github.com/efabless/openlane#quick-start. 
+Note that as of the time of this writing, the develop branch of open lane was used (i.e., git clone https://github.com/efabless/openlane.git --branch develop). If the docker is run manually, you'll need to specify rc5 instead of rc4.
+
+After ```make test``` succeeds, proceed to check out step next.
+
+# Check out
+```
+cd openlane/designs
+git clone https://github.com/SweeperAA/skywater130_decred_miner.git ./caravel
+cd caravel
+make uncompress
+```
+
+# Build decred flow
+At this point, there are two ways build the decred ASIC flow. At the time of this writing, each option has it's own deficiencies but you can get some intermediate results.
+
+Option 1: Build the macro independent of the caravel chip harness user space area.
 ```
 cd caravel/openlane
 make decred_top
 ```
+
+Option 2: Build the entire user space together with decred.
+```
+cd caravel/openlane
+make user_project_wrapper
+```
