 ## Guidelines
 
-1. make sure you've reviewed the code before you trigger it on a PR
-   that isn't your own
-2. be gentle, preferably don't run mass rebuilds / massive builds like
-   chromium on it
+1. Review the code of all PRs before triggering the bot on them.
+2. Be gentle; try not to run mass rebuilds or massive builds (like Chromium) on
+   it.
 
 ## Automatic Building
 
-Users who are _trusted_ or _known_ (see: Trusted Users vs Known Users)
-will have their PRs automatically trigger builds if their commits
-follow the well-defined format of Nixpkgs. Specifically: prefixing the
-commit title with the package attribute. This includes package bumps
-as well as other changes.

-If a PR is opened with many commits, it will create a single build job
-for all of the detected packages. If a PR is opened and many commits
-are pushed one by one to the open PR, many build jobs will be created.
+When opening a PR with multiple commits, ofborg creates a single build job for
+all detected packages. If multiple commits get pushed to a PR one-by-one, each
+detected package will get a separate build job.
 
-To disable automatic building of packages on a PR, add `[WIP]` to the
-PR's title, or the `2.status: work-in-progress` label.
+If the title of a PR begins with `WIP:`, contains `[WIP]` anywhere, or has the
+`2.status: work-in-progress` label, its packages are not built automatically.
+**Note**: Marking a PR as a draft does not prevent automatic builds.
 
 ## Commands

+The comment parser is line-based, so commentary can be interwoven with
+instructions for ofborg.
 
-1. To trigger the bot, the line _must_ start with a case
-   insensitive version of `@GrahamcOfBorg`.
-2. To use multiple commands, insert a bit of whitespace and then your
-   new command.
+1. To trigger the bot, the line _must_ start with `@ofborg` (case insensitive).
+   * **Note**: GitHub will not suggest `@ofborg` to you, but it will work all
+     the same. When in doubt, preview your comment and verify that `@ofborg`
+     links to https://github.com/ofborg/.
+2. To use multiple commands, separate them with whitespace. For examples, see
+   the "[Multiple Commands](#multiple-commands)" section.
 
-Commands:
-
-### test (added: 2017-11-24)
+### test
 
 ```
-@grahamcofborg test list of tests
+@ofborg test list of tests
 ```
 
-This will run `nix-build ./nixos/release.nix -A tests.list -A tests.of -A tests.tests` in

+Users](#trusted-users)" section.
 
 ### eval
 
 ```
-@grahamcofborg eval

+## Multiple Commands
 
-Multiple Commands:
+You can use multiple commands in a variety ways. Here are some valid
+combinations:
 
-```
-@grahamcofborg build list of attrs
-@grahamcofborg eval
-```
+*
+    ```
+    @ofborg build list of attrs
+    @ofborg eval
+    ```
 
-or even:
+*
+    ```
+    @ofborg build list of attrs @ofborg eval
+    ```
 
-```
-@grahamcofborg build list of attrs @grahamcofborg eval
-```
+*
+    ```
+    looks good to me!
+    @ofborg eval
+    @ofborg build list of attrs
+    ```
 
-This will also work:
+*
+    ```
+    @ofborg eval
+    @ofborg build list of attrs
+    looks good to me!
+    ```
 
-```
-looks good to me!
-@grahamcofborg build list of attrs
-```
+*
+    ```
+    @ofborg build list of attrs
+    @ofborg test list of attrs
+    ```
 
-And this is fine:
+* This will build `list`, `of`, `attrs`, `looks`, `good`, `to`, and `me!` (which is probably not what you want):
+    ```
+    @ofborg build list of attrs looks good to me!
+    ```
 
-```
-@grahamcofborg build list of attrs
-looks good to me!
-```
+## Trusted Users
 
-This is will build `list`, `of`, `attrs`, `looks`, `good`, `to`, `me!`:
+Trusted users have their builds and tests executed on _all_ available platforms,
+including those without good sandboxing. Because this exposes the host to a
+higher risk of security issues, the trusted users list consists of only
+well-known, trusted members of the community.

-## Trusted Users vs Known Users

-Known users have their builds executed on platforms with working
-sandboxing. At the time of writing, that means:
+At the time of writing, trusted users have their builds and tests run on these
+platforms:
 
  - `x86_64-linux`

-Trusted users have their builds executed on _all_ platforms, even if
-they don't have good sandboxing. This opens the host up to a higher
-risk of security issues, so only well known, trusted member of the
-community should be added to the trusted user list.
-
-At the time of writing, trusted users have their builds run on the
-following platforms:
-
- - `x86_64-linux`
- - `aarch64_linux`

 # Running meta checks locally
 
-```
+To run the meta checks, you will need the
+[`outpaths.nix`](./ofborg/src/outpaths.nix) file. You can acquire this file and
+run the checks themselves like so:
+
+```shell
 $ curl -o outpaths.nix https://raw.githubusercontent.com/NixOS/ofborg/released/ofborg/src/outpaths.nix
 $ GC_INITIAL_HEAP_SIZE=4g nix-env -f ./outpaths.nix -qaP --no-name --out-path --arg checkMeta true > out-paths

-# Running a builder
-
-It is recommended to create a special user for the ofBorg operation.
-This user should have git configuration for default username/email for
-non-interactive merges. For example:
-```
-git config --global user.email "graham+cofborg@example.com"
-git config --global user.name "GrahamCOfBorg"
-```
-
-
-```
-nix-shell ./shell.nix
-$ cd ofborg
-$ cargo build
-```
-
-```
-cargo build
-```
-
-then copy example.config.json to config.json and edit its vars. Set
-`nix.remote` to an empty string if you're not using the daemon.
-
-Run
-
-```
-./target/debug/builder ./config.json
-```
-
-
-Note the config.public.json for the public pieces of how I run ofborg,
-which is merged with config.known-users.json and a third private
-config file of credentials. These files contain some special keys like
-
- - known users
- - authorized users
- - log storage
-
-they are only used in the backend processing tasks, and there is no
-need for them on builders. However, to update the list in
-config.known-users.json, run `./scripts/update-known-users.sh`.
-
-In case you have a non-trivial setup on Linux, make sure that the ofborg
-user has access to `dev/kvm`, as it is needed for running tests.
-
-If you want to run multiple builder instances on the same physical
-machine please make sure they use different configs with different
-instance identity (same username/password is OK) and different
-repository paths. Running two builders with the same config risks data
-corruption.
