 * Set the `ENVBUILDER_GIT_HTTP_PROXY_URL=https://host:port` environment variable. This will specifically route traffic for Envbuilder's git operations and communication with the container registry without affecting other programs inside the container.
 
 Once traffic is routed to the proxy, you will need to install the proxy's CA certificate into Envbuilder. To do this, you can do one of the following:
-* Set `ENVBUILDER_SSL_CERT_BASE64=...` for Envbuilder to the base64 encoded value of your proxy's CA certificate. This will only apply to Envbuilder. Other TLS connections within your container will not be aware of this certificate.
+* Set `ENVBUILDER_SSL_CERT_BASE64=...` to the base64 encoded value of your proxy's CA certificate. This will only apply to Envbuilder. Other TLS connections within your container will not be aware of this certificate.
 * Mount the certificate file into the Envbuilder container and then set `ENVBUILDER_SSL_CERT_FILE=/path/to/cert.pem`.
 * Mount a directory containing all relevant CA certificates into the Envbuilder container and then set `ENVBUILDER_SSL_CERT_DIR=/path/to/certs/`.
