Describe the problems or issues found in the documentation
When installing with Conda, changing the first two commands from this:

mkdir /blazingsql # Make a blazingsql directory in root folder for Apache Calcite schema management. This will requirement will be removed soon.

chown <user_name> /blazingsql

to this:

sudo mkdir /blazingsql
sudo chmod 777 /blazingsql

resolved my comment in issue #72

Steps taken to verify documentation is incorrect
Installed in multiple Conda environments, with both blazingsql and blazingsql-nightly

Suggested fix for documentation
Add sudo before mkdir /blazingsql in the instructions to make the first line read:

sudo mkdir /blazingsql

Not sure changing the 2nd line is needed, or that 777 instead of <user_name> is a preferable option

We have made that directory no longer necessary. This has been fixed with PR PR-94. A new build should go out by the end of the day that will solve this issue for conda installs
