+# Configuration
+
+Piston provides many different configuration options to tweak Piston to meet your needs.
+
+Configuration is specified through environment variables, prefixed with `PISTON_`.
+
+## Log Level
+
+```yaml
+key: PISTON_LOG_LEVEL
+default: INFO
+```
+
+Level of log output to provide.
+
+One of `DEBUG`, `INFO`, `WARN`, `ERROR` or `NONE`
+
+## Bind Address
+
+```yaml
+key: PISTON_BIND_ADDRESS
+default: 0.0.0.0:2000
+```
+
+Port and IP address to bind the Piston API to.
+
+<!-- prettier-ignore -->
+!!! warning
+    Changing this value is not recommended.
+
+    This changes the bind address inside the container, and thus serves no purpose when running in a container
+
+## Data Directory
+
+```yaml
+key: PISTON_DATA_DIRECTORY
+default: /piston
+```
+
+Absolute path to piston related data, including packages and job contexts.
+
+<!-- prettier-ignore -->
+!!! warning
+    Changing this value is not recommended.
+
+    Some packages require absolute paths on disk at build time.
+    Due to this, some packages may break when changing this parameter.
+
+## Runner GID/UID range
+
+```yaml
+key:
+  - PISTON_RUNNER_UID_MIN
+  - PISTON_RUNNER_UID_MAX
+  - PISTON_RUNNER_GID_MIN
+  - PISTON_RUNNER_GID_MAX
+default:
+  - 1001
+  - 1500
+  - 1001
+  - 1500
+```
+
+UID and GID ranges to use when executing jobs.
+
+<!-- prettier-ignore -->
+!!! warning
+    Changing this value is not recommended.
+
+    The piston container creates 500 users and groups by default, and reserves user/group 1000 for running the API.
+    Any processes run by these users will be killed when cleaning up a job.
+
+## Disable Networking
+
+```yaml
+key: PISTON_DISABLE_NETWORKING
+default: true
+```
+
+Disallows access to `socket` syscalls, effectively disabling networking for jobs run by piston.
+
+## Max Process Count
+
+```yaml
+key: PISTON_MAX_PROCESS_COUNT
+default: 64
+```
+
+Maximum number of processess allowed to to have open for a job.
+
+Resists against exhausting the process table, causing a full system lockup.
+
+## Output Max Side
+
+```yaml
+key: PISTON_OUTPUT_MAX_SIZE
+default: 1024
+```
+
+Maximum size of stdio buffers for each job.
+
+Resist against run-away output which could lead to memory exhaustion.
+
+## Max Open Files
+
+```yaml
+key: PISTON_MAX_OPEN_FILES
+default: 64
+```
+
+Maximum number of open files at a given time by a job.
+
+Resists against writing many smaller files to exhaust inodes.
+
+## Max File Size
+
+```yaml
+key: PISTON_MAX_FILE_SIZE
+default: 10000000 #10MB
+```
+
+Maximum size for a singular file written to disk.
+
+Resists against large file writes to exhaust disk space.
+
+## Compile/Run memory limits
+
+```yaml
+key:
+  - PISTON_COMPILE_MEMORY_LIMIT
+  - PISTON_RUN_MEMORY_LIMIT
+default: -1
+```
+
+Maximum memory allowed by a stage in bytes.
+Use -1 for unlimited memory usage.
+
+Useful for running memory-limited contests.
+
+## Repository URL
+
+```yaml
+key: PISTON_REPO_URL
+default: https://github.com/engineer-man/piston/releases/download/pkgs/index
+```
+
+URL for repository index, where packages will be downloaded from.
