# installing from conda-forge

I have now used the info on the conda page of Sage manual in both variants proposed there (1. via mamba and 2. via conda with Python=3.7). In both cases the install seems to be successful but when activating the sage environment and entering it, I tried to follow the instructions in help() and build the tutorial, manual. etc. via the prescribed in the help() line, I ultimately get

```
sage: tutorial()

What am I doing wrongly?

It looks like the documentation hasn't been built. What did you do to try build it?

I just followed the instructions in the conda page in the manual. Installation was smooth, without any problems. Then, I entered the new sage environment after activating it. Then typed 'ḧelp()' and then typed 'tutorial()' according to the instruction in 'ḧelp()'. The rest is given in the text above.
