 1. Supply the key at the point of instantiatation for each domain. This will look something like:
 
-```{python}
+```python
 import ctxpy as ctx
 
 chem = ctx.Chemical(x_api_key='648a3d70')
 ```
 
 2. `ctx-python` comes with a command-line tool that will utilize the `.env` file that will store the key. If no key is supplied at instantiation, `ctx-python` will automatically attempt to load this file and use a key stored there.
-```{bash}
+```bash
 [user@host~]$ ctx_init --x-api-key 648a3d70
 ```
 This will result in the .env file having three new environment variables added to the file: `ctx_api_host`, `ctx_api_accept`, `ctx_x_api_key`.
