 This repository contains the basic configuration to work with emacs for compile LaTeX,
 Markdown and Docker tested with MacOS, Ubuntu and Windows.
 
-This configuration is used with the research seminar 101.
+# Python `venv`
+It has been tested that to work with Python's virtual environments (venv) on emacs, the venv must be created and activated on shell y using:
+
+``` shell
+$ python3 -m venv ~/.pyvenv/path/to/new/virtual/environment/
+$ source /path/to/new/virtual/environment/activate
+```
+
+after this we have to activate the virtual environment with emacs' command `pyvenv-workon` and select the environment to work with. 
+
+*consider tath a variable in `.emacs` must bedefined*
+
+```
+(setenv "WORKON_HOME" "~/.pyvenv/")
+```
+
+The commands to create a environmet is
+
+```
+python3 -m venv ~/.pyvenv/path/to/new/vir
+tual/environment/
+```
+
+then you need to acticate the environmet to install or update packages by:
+
+```
+source ~/.pyvenv/path/to/new/vir
+tual/environment/bin/activate
+```
+
+
+and the command to install a package is:
+
+```
+pip install package-name
+```
+
