+### Maintaining Bioconda package
+
+Bioconda hosts [augur’s conda package](http://bioconda.github.io/recipes/augur/README.html) and defines augur’s dependencies in [a conda recipe YAML file](https://github.com/bioconda/bioconda-recipes/blob/master/recipes/augur/meta.yaml).
+New releases on GitHub automatically trigger a new Bioconda release.
+
+To modify augur’s dependencies or other aspects of its conda environment, [follow Bioconda’s contributing guide](https://bioconda.github.io/contributor/index.html).
+You will need to update the existing recipe YAML locally and create a pull request on GitHub for testing and review.
+Add your GitHub username to the `recipe_maintainers` list, if this is your first time modifying the augur recipe.
+After a successful pull request review, Bioconda will automatically update the augur package that users download.

 ### Travis CI
 
 Branches and PRs are tested by Travis CI jobs configured in `.travis.yml`.

+## Using conda
+
+Install [Miniconda](https://docs.conda.io/en/latest/miniconda.html).
+Create a conda environment to install augur into and activate that environment.
+
+```bash
+conda create -n nextstrain
+conda activate nextstrain
+```
+
+Install augur and its dependencies into your environment.
+
+```bash
+conda install -c conda-forge -c bioconda augur
+```
+
+For a much faster installation process, use [mamba](https://github.com/TheSnakePit/mamba) as a drop-in replacement for conda.
+
+```bash
+conda install -c conda-forge mamba
+mamba install -c conda-forge -c bioconda augur

-## Using Conda
-
-Alternatively, augur itself and all of its dependencies can be installed into a [Conda](https://conda.io/miniconda.html) environment:
-
-    conda env create -f environment.yml
-
-> _By default this environment is named "augur" but you can change that by providing a name to the above command with `-n <your-env-name>`_
-
-When that finishes, the enviroment needs to be activated whenever you want to use augur:
-
-    conda activate augur
-
 ## Install from source
