+* `filters`: List of `Pleroma.Upload.Filter` to use.
+* `link_name`: When enabled Pleroma will add a `name` parameter to the url of the upload, for example `https://instance.tld/media/corndog.png?name=corndog.png`. This is needed to provide the correct filename in Content-Disposition headers when using filters like `Pleroma.Upload.Filter.Dedupe`
+* `base_url`: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.
+* `proxy_remote`: If you're using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.
+* `proxy_opts`: Proxy options, see `Pleroma.ReverseProxy` documentation.
+
+Note: `strip_exif` has been replaced by `Pleroma.Upload.Filter.Mogrify`.

+At this time, write CNAME to CDN in public_endpoint.
+* `streaming_enabled`: Enable streaming uploads, when enabled the file will be sent to the server in chunks as it's being read. This may be unsupported by some providers, try disabling this if you have upload problems.
+
+## Pleroma.Upload.Filter.Mogrify

+`Pleroma.Upload.Filter.Dedupe` before AnonymizeFilename.
+
+* `text`: Text to replace filenames in links. If empty, `{random}.extension` will be used. You can get the original filename extension by using `{extension}`, for example `custom-file-name.{extension}`.

+The keys in this section are the domain names that the policy should apply to.
+Each key should be assigned a list of users that should be allowed through by
+their ActivityPub ID.
+
+An example:
+
+```elixir
+config :pleroma, :mrf_user_allowlist,
+  "example.org": ["https://example.org/users/admin"]
+```
+
+## :web_push_encryption, :vapid_details
+
+Web Push Notifications configuration. You can use the mix task `mix web_push.gen.keypair` to generate it.
+
+* ``subject``: a mailto link for the administrative contact. It’s best if this email is not a personal email address, but rather a group email so that if a person leaves an organization, is unavailable for an extended period, or otherwise can’t respond, someone else on the list can.
+* ``public_key``: VAPID public key
+* ``private_key``: VAPID private key
+
+## Pleroma.Captcha
+* `enabled`: Whether the captcha should be shown on registration
+* `method`: The method/service to use for captcha
+* `seconds_valid`: The time in seconds for which the captcha is valid
+
+### Pleroma.Captcha.Kocaptcha
+Kocaptcha is a very simple captcha service with a single API endpoint,
+the source code is here: https://github.com/koto-bank/kocaptcha. The default endpoint
+`https://captcha.kotobank.ch` is hosted by the developer.
+
+* `endpoint`: the kocaptcha endpoint to use
+
+## :admin_token
+
+Allows to set a token that can be used to authenticate with the admin api without using an actual user by giving it as the 'admin_token' parameter. Example:
+
+```elixir
+config :pleroma, :admin_token, "somerandomtoken"
+```
+
+You can then do
+
+```sh
+curl "http://localhost:4000/api/pleroma/admin/invite_token?admin_token=somerandomtoken"
+```
+
+## Oban
+
+[Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
+
+Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
+* `repo` - app's Ecto repo (`Pleroma.Repo`)
+* `verbose` - logs verbosity
+* `prune` - non-retryable jobs [pruning settings](https://github.com/sorentwo/oban#pruning) (`:disabled` / `{:maxlen, value}` / `{:maxage, value}`)
+* `queues` - job queues (see below)
+
+Pleroma has the following queues:
+
+* `activity_expiration` - Activity expiration
+* `federator_outgoing` - Outgoing federation
+* `federator_incoming` - Incoming federation
+* `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
+* `transmogrifier` - Transmogrifier
+* `web_push` - Web push notifications
+* `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)
+
+Example:
+
+```elixir
+config :pleroma, Oban,
+  repo: Pleroma.Repo,
+  verbose: false,
+  prune: {:maxlen, 1500},
+  queues: [
+    federator_incoming: 50,
+    federator_outgoing: 50
+  ]
+```
+
+This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the number of max concurrent jobs set to `50`.
+
+### Migrating `pleroma_job_queue` settings
+
+`config :pleroma_job_queue, :queues` is replaced by `config :pleroma, Oban, :queues` and uses the same format (keys are queues' names, values are max concurrent jobs numbers).
+
+### Note on running with PostgreSQL in silent mode
+
+If you are running PostgreSQL in [`silent_mode`](https://postgresqlco.nf/en/doc/param/silent_mode?version=9.1), it's advised to set [`log_destination`](https://postgresqlco.nf/en/doc/param/log_destination?version=9.1) to `syslog`, 
+otherwise `postmaster.log` file may grow because of "you don't own a lock of type ShareLock" warnings (see https://github.com/sorentwo/oban/issues/52). 
+
+## :workers
+
+Includes custom worker options not interpretable directly by `Oban`.
+
+* `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
+
+Example:
+
+```elixir
+config :pleroma, :workers,
+  retries: [
+    federator_incoming: 5,
+    federator_outgoing: 5
+  ]
+```
+
+### Migrating `Pleroma.Web.Federator.RetryQueue` settings
+
+* `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
+* `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`
+* deprecated options: `max_jobs`, `initial_timeout`
+
+## Pleroma.Web.Metadata
+* `providers`: a list of metadata providers to enable. Providers available:
+  * Pleroma.Web.Metadata.Providers.OpenGraph
+  * Pleroma.Web.Metadata.Providers.TwitterCard
+  * Pleroma.Web.Metadata.Providers.RelMe - add links from user bio with rel=me into the `<header>` as `<link rel=me>`
+* `unfurl_nsfw`: If set to `true` nsfw attachments will be shown in previews
+
+## :rich_media
+* `enabled`: if enabled the instance will parse metadata from attached links to generate link previews
+* `ignore_hosts`: list of hosts which will be ignored by the metadata parser. For example `["accounts.google.com", "xss.website"]`, defaults to `[]`.
+* `ignore_tld`: list TLDs (top-level domains) which will ignore for parse metadata. default is ["local", "localdomain", "lan"]
+* `parsers`: list of Rich Media parsers
+
+## :fetch_initial_posts
+* `enabled`: if enabled, when a new user is federated with, fetch some of their latest posts
+* `pages`: the amount of pages to fetch
+
+## :hackney_pools
+
+Advanced. Tweaks Hackney (http client) connections pools.
+
+There's three pools used:
+
+* `:federation` for the federation jobs.
+  You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
+* `:media` for rich media, media proxy
+* `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
+
+For each pool, the options are:
+
+* `max_connections` - how much connections a pool can hold
+* `timeout` - retention duration for connections
+
+## :auto_linker
+
+Configuration for the `auto_linker` library:
+
+* `class: "auto-linker"` - specify the class to be added to the generated link. false to clear
+* `rel: "noopener noreferrer"` - override the rel attribute. false to clear
+* `new_window: true` - set to false to remove `target='_blank'` attribute
+* `scheme: false` - Set to true to link urls with schema `http://google.com`
+* `truncate: false` - Set to a number to truncate urls longer then the number. Truncated urls will end in `..`
+* `strip_prefix: true` - Strip the scheme prefix
+* `extra: false` - link urls with rarely used schemes (magnet, ipfs, irc, etc.)
+
+Example:
+
+```elixir
+config :auto_linker,
+  opts: [
+    scheme: true,
+    extra: true,
+    class: false,
+    strip_prefix: false,
+    new_window: false,
+    rel: "ugc"
+  ]
+```
+
+## Pleroma.Scheduler
+
+Configuration for [Quantum](https://github.com/quantum-elixir/quantum-core) jobs scheduler.
+
+See [Quantum readme](https://github.com/quantum-elixir/quantum-core#usage) for the list of supported options. 
+
+Example:
+
+```elixir
+config :pleroma, Pleroma.Scheduler,
+  global: true,
+  overlap: true,
+  timezone: :utc,
+  jobs: [{"0 */6 * * * *", {Pleroma.Web.Websub, :refresh_subscriptions, []}}]
+```
+
+The above example defines a single job which invokes `Pleroma.Web.Websub.refresh_subscriptions()` every 6 hours ("0 */6 * * * *", [crontab format](https://en.wikipedia.org/wiki/Cron)).
+
+## Pleroma.ScheduledActivity
+
+* `daily_user_limit`: the number of scheduled activities a user is allowed to create in a single day (Default: `25`)
+* `total_user_limit`: the number of scheduled activities a user is allowed to create in total (Default: `300`)
+* `enabled`: whether scheduled activities are sent to the job queue to be executed
+
+## Pleroma.ActivityExpiration
+
+# `enabled`: whether expired activities will be sent to the job queue to be deleted
+
+## Pleroma.Web.Auth.Authenticator
+
+* `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator
+* `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication
+
+## :ldap
+
+Use LDAP for user authentication.  When a user logs in to the Pleroma
+instance, the name and password will be verified by trying to authenticate
+(bind) to an LDAP server.  If a user exists in the LDAP directory but there
+is no account with the same name yet on the Pleroma instance then a new
+Pleroma account will be created with the same name as the LDAP user name.
+
+* `enabled`: enables LDAP authentication
+* `host`: LDAP server hostname
+* `port`: LDAP port, e.g. 389 or 636
+* `ssl`: true to use SSL, usually implies the port 636
+* `sslopts`: additional SSL options
+* `tls`: true to start TLS, usually implies the port 389
+* `tlsopts`: additional TLS options
+* `base`: LDAP base, e.g. "dc=example,dc=com"
+* `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
+
+## BBS / SSH access
+
+To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
+
+```exs
+app_dir = File.cwd!
+priv_dir = Path.join([app_dir, "priv/ssh_keys"])
+
+config :esshd,
+  enabled: true,
+  priv_dir: priv_dir,
+  handler: "Pleroma.BBS.Handler",
+  port: 10_022,
+  password_authenticator: "Pleroma.BBS.Authenticator"
+```
+
+Feel free to adjust the priv_dir and port number. Then you will have to create the key for the keys (in the example `priv/ssh_keys`) and create the host keys with `ssh-keygen -m PEM -N "" -b 2048 -t rsa -f ssh_host_rsa_key`. After restarting, you should be able to connect to your Pleroma instance with `ssh username@server -p $PORT`
+
+## :auth
+
+* `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator
+* `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication
+
+Authentication / authorization settings.
+
+* `auth_template`: authentication form template. By default it's `show.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/show.html.eex`.
+* `oauth_consumer_template`: OAuth consumer mode authentication form template. By default it's `consumer.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/consumer.html.eex`.
+* `oauth_consumer_strategies`: the list of enabled OAuth consumer strategies; by default it's set by `OAUTH_CONSUMER_STRATEGIES` environment variable. Each entry in this space-delimited string should be of format `<strategy>` or `<strategy>:<dependency>` (e.g. `twitter` or `keycloak:ueberauth_keycloak_strategy` in case dependency is named differently than `ueberauth_<strategy>`).
+
+## :email_notifications
+
+Email notifications settings.
+
+  - digest - emails of "what you've missed" for users who have been
+    inactive for a while.
+    - active: globally enable or disable digest emails
+    - schedule: When to send digest email, in [crontab format](https://en.wikipedia.org/wiki/Cron).
+      "0 0 * * 0" is the default, meaning "once a week at midnight on Sunday morning"
+    - interval: Minimum interval between digest emails to one user
+    - inactivity_threshold: Minimum user inactivity threshold
+
+## Pleroma.Emails.UserEmail
+
+- `:logo` - a path to a custom logo. Set it to `nil` to use the default Pleroma logo.
+- `:styling` - a map with color settings for email templates.
+
+## OAuth consumer mode
+
+OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
+Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
+
+Note: each strategy is shipped as a separate dependency; in order to get the strategies, run `OAUTH_CONSUMER_STRATEGIES="..." mix deps.get`,
+e.g. `OAUTH_CONSUMER_STRATEGIES="twitter facebook google microsoft" mix deps.get`.
+The server should also be started with `OAUTH_CONSUMER_STRATEGIES="..." mix phx.server` in case you enable any strategies.
+
+Note: each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
+
+Note: make sure that `"SameSite=Lax"` is set in `extra_cookie_attrs` when you have this feature enabled. OAuth consumer mode will not work with `"SameSite=Strict"`
+
+* For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback
+
+* For Facebook, [register an app](https://developers.facebook.com/apps), configure callback URL to https://<your_host>/oauth/facebook/callback, enable Facebook Login service at https://developers.facebook.com/apps/<app_id>/fb-login/settings/
+
+* For Google, [register an app](https://console.developers.google.com), configure callback URL to https://<your_host>/oauth/google/callback
+
+* For Microsoft, [register an app](https://portal.azure.com), configure callback URL to https://<your_host>/oauth/microsoft/callback
+
+Once the app is configured on external OAuth provider side, add app's credentials and strategy-specific settings (if any — e.g. see Microsoft below) to `config/prod.secret.exs`,
+per strategy's documentation (e.g. [ueberauth_twitter](https://github.com/ueberauth/ueberauth_twitter)). Example config basing on environment variables:
+
+```elixir
+# Twitter
+config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
+  consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
+  consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")
+
+# Facebook
+config :ueberauth, Ueberauth.Strategy.Facebook.OAuth,
+  client_id: System.get_env("FACEBOOK_APP_ID"),
+  client_secret: System.get_env("FACEBOOK_APP_SECRET"),
+  redirect_uri: System.get_env("FACEBOOK_REDIRECT_URI")
+
+# Google
+config :ueberauth, Ueberauth.Strategy.Google.OAuth,
+  client_id: System.get_env("GOOGLE_CLIENT_ID"),
+  client_secret: System.get_env("GOOGLE_CLIENT_SECRET"),
+  redirect_uri: System.get_env("GOOGLE_REDIRECT_URI")
+
+# Microsoft
+config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
+  client_id: System.get_env("MICROSOFT_CLIENT_ID"),
+  client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
+
+config :ueberauth, Ueberauth,
+  providers: [
+    microsoft: {Ueberauth.Strategy.Microsoft, [callback_params: []]}
+  ]
+
+# Keycloak
+# Note: make sure to add `keycloak:ueberauth_keycloak_strategy` entry to `OAUTH_CONSUMER_STRATEGIES` environment variable
+keycloak_url = "https://publicly-reachable-keycloak-instance.org:8080"
+
+config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
+  client_id: System.get_env("KEYCLOAK_CLIENT_ID"),
+  client_secret: System.get_env("KEYCLOAK_CLIENT_SECRET"),
+  site: keycloak_url,
+  authorize_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/auth",
+  token_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/token",
+  userinfo_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/userinfo",
+  token_method: :post
+
+config :ueberauth, Ueberauth,
+  providers: [
+    keycloak: {Ueberauth.Strategy.Keycloak, [uid_field: :email]}
+  ]
+```
+
+## OAuth 2.0 provider - :oauth2
+
+Configure OAuth 2 provider capabilities:
+
+* `token_expires_in` - The lifetime in seconds of the access token.
+* `issue_new_refresh_token` - Keeps old refresh token or generate new refresh token when to obtain an access token.
+* `clean_expired_tokens` - Enable a background job to clean expired oauth tokens. Defaults to `false`.
+* `clean_expired_tokens_interval` - Interval to run the job to clean expired tokens. Defaults to `86_400_000` (24 hours).
+
+## :emoji
+* `shortcode_globs`: Location of custom emoji files. `*` can be used as a wildcard. Example `["/emoji/custom/**/*.png"]`
+* `pack_extensions`: A list of file extensions for emojis, when no emoji.txt for a pack is present. Example `[".png", ".gif"]`
+* `groups`: Emojis are ordered in groups (tags). This is an array of key-value pairs where the key is the groupname and the value the location or array of locations. `*` can be used as a wildcard. Example `[Custom: ["/emoji/*.png", "/emoji/custom/*.png"]]`
+* `default_manifest`: Location of the JSON-manifest. This manifest contains information about the emoji-packs you can download. Currently only one manifest can be added (no arrays).
+* `shared_pack_cache_seconds_per_file`: When an emoji pack is shared, the archive is created and cached in
+  memory for this amount of seconds multiplied by the number of files.
+
+## Database options
+
+### RUM indexing for full text search
+* `rum_enabled`: If RUM indexes should be used. Defaults to `false`.
+
+RUM indexes are an alternative indexing scheme that is not included in PostgreSQL by default. While they may eventually be mainlined, for now they have to be installed as a PostgreSQL extension from https://github.com/postgrespro/rum.
+
+Their advantage over the standard GIN indexes is that they allow efficient ordering of search results by timestamp, which makes search queries a lot faster on larger servers, by one or two orders of magnitude. They take up around 3 times as much space as GIN indexes.
+
+To enable them, both the `rum_enabled` flag has to be set and the following special migration has to be run:
+
+`mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/`
+
+This will probably take a long time.
+
+## :rate_limit
+
+This is an advanced feature and disabled by default.
+
+If your instance is behind a reverse proxy you must enable and configure [`Pleroma.Plugs.RemoteIp`](#pleroma-plugs-remoteip).
+
+A keyword list of rate limiters where a key is a limiter name and value is the limiter configuration. The basic configuration is a tuple where:
+
+* The first element: `scale` (Integer). The time scale in milliseconds.
+* The second element: `limit` (Integer). How many requests to limit in the time scale provided.
+
+It is also possible to have different limits for unauthenticated and authenticated users: the keyword value must be a list of two tuples where the first one is a config for unauthenticated users and the second one is for authenticated.
+
+See [`Pleroma.Plugs.RateLimiter`](Pleroma.Plugs.RateLimiter.html) documentation for examples.
+
+Supported rate limiters:
+
+* `:search` for the search requests (account & status search etc.)
+* `:app_account_creation` for registering user accounts from the same IP address
+* `:relations_actions` for actions on relations with all users (follow, unfollow)
+* `:relation_id_action` for actions on relation with a specific user (follow, unfollow)
+* `:statuses_actions` for create / delete / fav / unfav / reblog / unreblog actions on any statuses
+* `:status_id_action` for fav / unfav or reblog / unreblog actions on the same status by the same user
+
+## :web_cache_ttl
+
+The expiration time for the web responses cache. Values should be in milliseconds or `nil` to disable expiration.
+
+Available caches:
+
+* `:activity_pub` - activity pub routes (except question activities). Defaults to `nil` (no expiration).
+* `:activity_pub_question` - activity pub routes (question activities). Defaults to `30_000` (30 seconds).
+
+## Pleroma.Plugs.RemoteIp
+
+**If your instance is not behind at least one reverse proxy, you should not enable this plug.**
+
+`Pleroma.Plugs.RemoteIp` is a shim to call [`RemoteIp`](https://git.pleroma.social/pleroma/remote_ip) but with runtime configuration.
+
+Available options:
+
+* `enabled` - Enable/disable the plug. Defaults to `false`.
+* `headers` - A list of strings naming the `req_headers` to use when deriving the `remote_ip`. Order does not matter. Defaults to `~w[forwarded x-forwarded-for x-client-ip x-real-ip]`.
+* `proxies` - A list of strings in [CIDR](https://en.wikipedia.org/wiki/CIDR) notation specifying the IPs of known proxies. Defaults to `[]`.
+* `reserved` - Defaults to [localhost](https://en.wikipedia.org/wiki/Localhost) and [private network](https://en.wikipedia.org/wiki/Private_network).

 ### システムを準備する
 
 * まずシステムをアップデートしてください。
 ```
-apt update && apt dist-upgrade
+sudo apt update
+sudo apt full-upgrade
 ```
 
-* 複数のツールとpostgresqlをインストールします。あとで必要になるので。
+* 上記に挙げたパッケージをインストールしておきます。
 ```
-apt install git build-essential openssl ssh sudo postgresql-9.6 postgresql-contrib-9.6
+sudo apt install git build-essential postgresql postgresql-contrib
 ```
-(postgresqlのバージョンは、あなたのディストロにあわせて変えてください。または、バージョン番号がいらないかもしれません。)
+
 
 ### ElixirとErlangをインストールします
 
 * Erlangのリポジトリをダウンロードおよびインストールします。
 ```
-wget -P /tmp/ https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb && sudo dpkg -i /tmp/erlang-solutions_1.0_all.deb
+wget -P /tmp/ https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
+sudo dpkg -i /tmp/erlang-solutions_1.0_all.deb
 ```
 
 * ElixirとErlangをインストールします、
 ```
-apt update && apt install elixir erlang-dev erlang-parsetools erlang-xmerl erlang-tools erlang-ssh
+sudo apt update
+sudo apt install elixir erlang-dev erlang-parsetools erlang-xmerl erlang-tools erlang-ssh
 ```
 
 ### Pleroma BE (バックエンド) をインストールします
 
-*  新しいユーザーを作ります。
+*  Pleroma用に新しいユーザーを作ります。
-```
-adduser pleroma
-``` 
-(Give it any password you want, make it STRONG)
 
-*  新しいユーザーをsudoグループに入れます。
 ```
-usermod -aG sudo pleroma
+sudo useradd -r -s /bin/false -m -d /var/lib/pleroma -U pleroma
 ```
 
-*  新しいユーザーに変身し、ホームディレクトリに移動します。
+**注意**: Pleromaユーザとして単発のコマンドを実行したい場合はは、`sudo -Hu pleroma command` を使ってください。シェルを使いたい場合は `sudo -Hu pleroma $SHELL`です。もし `sudo` を使わない場合は、rootユーザで `su -l pleroma -s $SHELL -c 'command'` とすることでコマンドを、`su -l pleroma -s $SHELL` とすることでシェルを開始できます。
-```
-su pleroma
-cd ~
-```
 
 *  Gitリポジトリをクローンします。
 ```
-git clone -b master https://git.pleroma.social/pleroma/pleroma
+sudo mkdir -p /opt/pleroma
+sudo chown -R pleroma:pleroma /opt/pleroma
+sudo -Hu pleroma git clone -b master https://git.pleroma.social/pleroma/pleroma /opt/pleroma
 ```
 
 *  新しいディレクトリに移動します。
 ```
-cd pleroma/
+cd /opt/pleroma
 ```
 
 * Pleromaが依存するパッケージをインストールします。Hexをインストールしてもよいか聞かれたら、yesを入力してください。
 ```
-mix deps.get
+sudo -Hu pleroma mix deps.get
 ```
 
 * コンフィギュレーションを生成します。
 ```
-mix pleroma.instance gen
+sudo -Hu pleroma mix pleroma.instance gen
 ```
     * rebar3をインストールしてもよいか聞かれたら、yesを入力してください。
-    * この処理には時間がかかります。私もよく分かりませんが、何らかのコンパイルが行われているようです。
+    * このときにpleromaの一部がコンパイルされるため、この処理には時間がかかります。
-    * あなたのインスタンスについて、いくつかの質問があります。その回答は `config/generated_config.exs` というコンフィギュレーションファイルに保存されます。
+    * あなたのインスタンスについて、いくつかの質問されます。この質問により `config/generated_config.exs` という設定ファイルが生成されます。
 
-**注意**: メディアプロクシを有効にすると回答して、なおかつ、キャッシュのURLは空欄のままにしている場合は、`generated_config.exs` を編集して、`base_url` で始まる行をコメントアウトまたは削除してください。そして、上にある行の `true` の後にあるコンマを消してください。
 
 * コンフィギュレーションを確認して、もし問題なければ、ファイル名を変更してください。
 ```
 mv config/{generated_config.exs,prod.secret.exs}
 ```
 
-* これまでのコマンドで、すでに `config/setup_db.psql` というファイルが作られています。このファイルをもとに、データベースを作成します。
+* 先程のコマンドで、すでに `config/setup_db.psql` というファイルが作られています。このファイルをもとに、データベースを作成します。
 ```
-sudo su postgres -c 'psql -f config/setup_db.psql'
+sudo -Hu pleroma mix pleroma.instance gen
 ```
 
-* そして、データベースのミグレーションを実行します。
+* そして、データベースのマイグレーションを実行します。
 ```
-MIX_ENV=prod mix ecto.migrate
+sudo -Hu pleroma MIX_ENV=prod mix ecto.migrate
 ```
 
-* Pleromaを起動できるようになりました。
+* これでPleromaを起動できるようになりました。
 ```
-MIX_ENV=prod mix phx.server
+sudo -Hu pleroma MIX_ENV=prod mix phx.server
 ```
 
-### インストールを終わらせる
+### インストールの最終段階
 
-あなたの新しいインスタンスを世界に向けて公開するには、nginxまたは何らかのウェブサーバー (プロクシ) を使用する必要があります。また、Pleroma のためにシステムサービスファイルを作成する必要があります。
+あなたの新しいインスタンスを世界に向けて公開するには、nginx等のWebサーバやプロキシサーバをPleromaの前段に使用する必要があります。また、Pleroma のためにシステムサービスファイルを作成する必要があります。
 
 #### Nginx
 
 * まだインストールしていないなら、nginxをインストールします。
 ```
-apt install nginx
+sudo apt install nginx
 ```
 
 * SSLをセットアップします。他の方法でもよいですが、ここではcertbotを説明します。
 certbotを使うならば、まずそれをインストールします。
 ```
-apt install certbot
+sudo apt install certbot
 ```
 そしてセットアップします。
 ```
-mkdir -p /var/lib/letsencrypt/.well-known
+sudo mkdir -p /var/lib/letsencrypt/
-% certbot certonly --email your@emailaddress --webroot -w /var/lib/letsencrypt/ -d yourdomain
+sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --standalone
 ```
-もしうまくいかないときは、先にnginxを設定してください。ssl "on" を "off" に変えてから再試行してください。
+もしうまくいかないときは、nginxが正しく動いていない可能性があります。先にnginxを設定してください。ssl "on" を "off" に変えてから再試行してください。
 
 ---
 
-* nginxコンフィギュレーションの例をnginxフォルダーにコピーします。
+* nginxの設定ファイルサンプルをnginxフォルダーにコピーします。
 ```
-cp /home/pleroma/pleroma/installation/pleroma.nginx /etc/nginx/sites-enabled/pleroma.nginx
+sudo cp /opt/pleroma/installation/pleroma.nginx /etc/nginx/sites-available/pleroma.nginx
+sudo ln -s /etc/nginx/sites-available/pleroma.nginx /etc/nginx/sites-enabled/pleroma.nginx
 ```
 
-* nginxを起動する前に、コンフィギュレーションを編集してください。例えば、サーバー名、証明書のパスなどを変更する必要があります。
+* nginxを起動する前に、設定ファイルを編集してください。例えば、サーバー名、証明書のパスなどを変更する必要があります。
 * nginxを再起動します。
 ```
-systemctl reload nginx.service
+sudo systemctl enable --now nginx.service
 ```
 
+もし証明書を更新する必要が出てきた場合には、nginxの関連するlocationブロックのコメントアウトを外し、以下のコマンドを動かします。
+
+```
+sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --webroot -w /var/lib/letsencrypt/
+```
+
+#### 他のWebサーバやプロキシ
+これに関してはサンプルが `/opt/pleroma/installation/` にあるので、探してみてください。
+
 #### Systemd サービス
 
-* サービスファイルの例をコピーします。
+* サービスファイルのサンプルをコピーします。
 ```
-cp /home/pleroma/pleroma/installation/pleroma.service /usr/lib/systemd/system/pleroma.service
+sudo cp /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service
 ```
 
-* サービスファイルを変更します。すべてのパスが正しいことを確認してください。また、`[Service]` セクションに以下の行があることを確認してください。
+* サービスファイルを変更します。すべてのパスが正しいことを確認してください
+* サービスを有効化し `pleroma.service` を開始してください
 ```
-Environment="MIX_ENV=prod"
+sudo systemctl enable --now pleroma.service
 ```
 
-* `pleroma.service` を enable および start してください。
+#### 初期ユーザの作成
+
+新たにインスタンスを作成したら、以下のコマンドにより管理者権限を持った初期ユーザを作成できます。
+
 ```
-systemctl enable --now pleroma.service
+sudo -Hu pleroma MIX_ENV=prod mix pleroma.user new <username> <your@emailaddress> --admin
 ```
 
-#### モデレーターを作る
+#### その他の設定とカスタマイズ
-
-新たにユーザーを作ったら、モデレーター権限を与えたいかもしれません。以下のタスクで可能です。
-```
-mix set_moderator username [true|false]
-```
-
-モデレーターはすべてのポストを消すことができます。将来的には他のことも可能になるかもしれません。
-
-#### メディアプロクシを有効にする
-
-`generate_config` でメディアプロクシを有効にしているなら、すでにメディアプロクシが動作しています。あとから設定を変更したいなら、[How to activate mediaproxy](How-to-activate-mediaproxy) を見てください。
