 # Epidata API Client Libraries
 
-For anyone looking for COVIDCast data, please visit our [COVIDCast Libraries](covidcast_clients.md).
+To access Delphi Epidata, we recommend using the following client libraries:
 
-We are currently working on fully-featured Epidata clients for R and Python. They are not ready
-for release yet, but you can track our development progress and help us test them out at:
+- R: [epidatr](https://cmu-delphi.github.io/epidatr/).
+- Python: [delphi-epidata](https://pypi.org/project/delphi-epidata/) (soon to be replaced [epidatpy](https://github.com/cmu-delphi/epidatpy)).
+- Javascript: [delphi-epidata](https://github.com/cmu-delphi/delphi-epidata/blob/master/src/client/delphi_epidata.js).
 
-* [epidatr](https://github.com/cmu-delphi/epidatr)
-* [epidatpy](https://github.com/cmu-delphi/epidatpy)
+For anyone looking for COVIDCast data, please visit our [COVIDCast Libraries](covidcast_clients.md).
 
-In the meantime, minimalist Epidata clients remain available for
-[JavaScript](https://github.com/cmu-delphi/delphi-epidata/blob/master/src/client/delphi_epidata.js),
-[Python](https://github.com/cmu-delphi/delphi-epidata/blob/master/src/client/delphi_epidata.py),
-and
-[R](https://github.com/cmu-delphi/delphi-epidata/blob/master/src/client/delphi_epidata.R).

 `20200401` and `20200405-20200414` (11 days total).
 
 ### JavaScript (in a web browser)
 
-The minimalist JavaScript client does not currently support API keys. If you need API key support in JavaScript, contact [email protected].

 <!-- Imports -->
 <script src="delphi_epidata.js"></script>
 <!-- Fetch data -->
 <script>
-  EpidataAsync.covidcast('fb-survey', 'smoothed_cli', 'day', 'county', [20200401, EpidataAsync.range(20200405, 20200414)], '06001').then((res) => {

   });
 </script>

+```
 
 ### Python
 
+First, install `delphi-epidata` using pip:
 
-Optionally install the [package from PyPI](https://pypi.org/project/delphi-epidata/) using pip(env):
-````bash
+```bash
 pip install delphi-epidata
-````
+```
 
-Otherwise, place
-[`delphi_epidata.py`](https://github.com/cmu-delphi/delphi-epidata/blob/master/src/client/delphi_epidata.py)
-in the same directory as your Python script.
+Then, run the following Python code:
 
-````python
+```python
 # Import
 from delphi_epidata import Epidata
 # [Optional] configure your API key, if desired
 #Epidata.auth = ('epidata', <your API key>)
 # Fetch data
 res = Epidata.covidcast('fb-survey', 'smoothed_cli', 'day', 'county', [20200401, Epidata.range(20200405, 20200414)], '06001')
 print(res['result'], res['message'], len(res['epidata']))
-````
+```
 
 ### R
 
+First, install `epidatr` from CRAN:
+
+```R
+pak::pkg_install("epidatr")
+```
+
+Then, run the following R code:
 
-````R
+```R
 # [Optional] configure your API key, if desired
-#option('epidata.auth', <your API key>)
+#Sys.setenv('DELPHI_EPIDATA_KEY', <your API key>)
 # Import
-source('delphi_epidata.R')
+library('epidatr')
 # Fetch data
-res <- Epidata$covidcast('fb-survey', 'smoothed_cli', 'day', 'county', list(20200401, Epidata$range(20200405, 20200414)), '06001')
-cat(paste(res$result, res$message, length(res$epidata), "\n"))
-````
+res <- pub_covidcast('fb-survey', 'smoothed_cli', 'county', 'day', '06001', epirange(20200401, 20200414))

 # COVIDcast Libraries
 
-Dedicated COVIDcast access and analysis libraries are available for several languages:
+To access COVIDcast data, we recommend using the following client libraries:
 
-* R: [covidcast](https://cmu-delphi.github.io/covidcast/covidcastR/)
-* Python: [covidcast](https://cmu-delphi.github.io/covidcast/covidcast-py/html/)
+- R: [epidatr](https://cmu-delphi.github.io/epidatr/).
+- Python: [covidcast](https://cmu-delphi.github.io/covidcast/covidcast-py/html/) (soon to be replaced [epidatpy](https://github.com/cmu-delphi/epidatpy)).
 
 These packages provide a convenient way to obtain COVIDcast data as a data frame
 ready to be used in further analyses and provide convenient mapping and
 analysis functions. For installation instructions and examples, consult their
 respective webpages.
