 ## Local Data Directories
 
 The recommended way of setting your local data directory is to set the `SPEDAS_DATA_DIR` environment variable. `SPEDAS_DATA_DIR` acts as a root data directory for all missions, and will also be used by IDL (if you’re running a recent copy of the bleeding edge).
 
 Mission specific data directories (e.g., `MMS_DATA_DIR` for MMS, `THM_DATA_DIR` for THEMIS) can also be set, and these will override `SPEDAS_DATA_DIR`

+Pytplot is a separate project, that replicates the IDL "tplot" functionality. Pyspedas uses a modified version of pytplot with matplotlib as the plotting library.
