 ## Environment variables {#env}
 
-A list of environment variables that are defined in the {{ sf-name }} runtime environment and can be used by functions.
+The table provides a list of environment variables defined in the {{ sf-name }} runtime and available to a function. You cannot override these.
 
 | Key | Value |
 | ---- | ---- |
 | `_HANDLER` | The handler location specified for the function. |
 | `AWS_LAMBDA_RUNTIME_API` | The runtime host and API port. |
-| `LAMBDA_RUNTIME_DIR` | The path to the runtime libraries. |
-| `LAMBDA_TASK_ROOT` | The path to your function code. |
+| `LAMBDA_RUNTIME_DIR` | Path to runtime libraries. |

-You can [add environment variables](../../operations/function/version-manage.md#version-env) in the management console.
+You can [add other environment variables](../../operations/function/version-manage.md#version-env) when creating a function version. Environment variables, including variable names, are [limited](../limits.md#limits) to 4 KB of space.
+
+You cannot calculate environment variables. Environment variable values are string constants. You can only calculate these within function code.
+
+You can retrieve environment variables using standard programming language tools.
 
 ## User files {#files}
 
 User files are stored in two directories:
 
 - `/function/code`: The user's working directory. It contains all the code of your function and all the files uploaded as a ZIP archive. You can use a relative path to access it.
-- `/tmp`: A directory to store temporary files used for optimizing repeated function instance calls. [The maximum size of temporary files is limited](../limits.md#limits) to 512 MB.
+- `/tmp`: directory for temporary files. It is used by the service to optimize repeat function calls that are sequentially processed by one of its instances. When a function instance runs its course, its data in `/tmp` are deleted. [The maximum size](../limits.md#limits) of temporary files is limited to 512 MB.

+The runtime environment is selected when creating a function. It provides additional libraries and environment variables that can be accessed from the function code. You can change the selected runtime environment by updating the function configuration. The [preloaded runtime environment](./preload-runtime.md) automatically updates to the latest version in the function version settings.
 
 Runtime environment characteristics:
 
 - Operating system: Ubuntu 18.04 LTS.
-- Linux Kernel v. 4.14.
+- Linux kernel: 4.19.
 
-When invoking a function, the service tries to use the runtime environment from the previous invocation if it's still available. This lets you save time preparing the runtime environment and resources, such as DB connections and temporary files, which don't have to be re-created when the runtime environment is used again.
+A first function call creates a function instance. The service uses existing function instances for new calls, if available. This lets you save time preparing the runtime environment and resources, such as DB connections and temporary files, which don't have to be re-created when the runtime environment is used again.
