# Hi Steemians, let's build BOTS! #### On this blog I want to document my progress in implementing bots for the STEEM blockchain. https://steemitimages.com/DQmYBEXnPDCks41VWPfQr5HAfE6kfMoH6NYArDbrkzND7pT/robots-764951_1280.png Image Source: https://pixabay.com/de/roboter-computer-bots-charakter-764951/ In the last post we ordered and installed a brand new virtualized Ubuntu 16 server. Today I want to install the official steem-python library. One can find the official documentation at the [Steem Developer Portal](https://developers.steem.io) https://steemitimages.com/DQmeqUvA1F1QdB5qUezHcqiyyEQ1EgbKyu1vfoAhHsdmYVe/DeveloperPortal.png The **Getting Started** link under the PYTHON menu item forwards us to the official steem-python documentation http://steem.readthedocs.io/en/latest/ https://steemitimages.com/DQmVVeGx6w8oGm1crYHaaAo1WWbVZ4QTKhtjbSSQ8gg2H5G/ReadTheDocs.png So, let's start the installation according to the instructions on the website. Lets type ``` ubuntu@botsultant:~$ pip install -U steem ``` #### and we get: ``` The program 'pip' is currently not installed. You can install it by typing: sudo apt install python-pip ``` #### Thank you very much, Steemit inc. I will follow now [the installation guide](https://steemit.com/steem-python/@felixxx/learning-python-with-felixxx-1-setup-and-first-script) from @felixxx. First let's update ubuntu. ``` sudo apt-get update ``` #### ``` Hit:1 http://archive.ubuntu.com/ubuntu xenial InRelease Get:2 http://archive.ubuntu.com/ubuntu xenial-updates InRelease [102 kB] Get:3 http://archive.ubuntu.com/ubuntu xenial-backports InRelease [102 kB] Get:4 http://security.ubuntu.com/ubuntu xenial-security InRelease [102 kB] Get:5 http://archive.ubuntu.com/ubuntu xenial-updates/universe amd64 Packages [572 kB] Fetched 878 kB in 0s (1,608 kB/s) Reading package lists...
