 # GHCup metadata
 
-## Adding a new GHC version
+## For end users
+
+### Metadata variants (distribution channels)
+
+* `ghcup-A.B.C.yaml`: this is the main metadata and what ghcup uses by default
+* `ghcup-vanilla-A.B.C.yaml`: this is similar to `ghcup-A.B.C.yaml`, but only uses upstream bindists (no patches/fixes are applied, no missing platforms added)
+* `ghcup-prereleases-A.B.C.yaml`: this contains pre-releases of all tools
+* `ghcup-cross-A.B.C.yaml`: this contains (usually experimental) cross compilers
+
+### Using the metadata
+
+If you want access to both pre-releases and cross compilers, run:
+
+```
+ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml
+ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-cross-0.0.8.yaml
+```
+
+## For contributors
+
+### Adding a new GHC version
 
 1. open the latest `ghcup-<yaml-ver>.yaml`
 2. find the latest ghc version (in yaml tree e.g. `ghcupDownloads -> GHC -> 8.10.7`)
 3. copy-paste it
 4. adjust the version, tags, changelog, source url
 5. adjust the various bindist urls (make sure to also change the yaml anchors)
-6. build the `ghcup-gen` binary from the [ghcup repo](https://gitlab.haskell.org/haskell/ghcup-hs)
-7. run `ghcup-gen -- check          -f ghcup-<yaml-ver>.yaml`
-8. run `ghcup-gen -- check-tarballs -f ghcup-<yaml-ver>.yaml -u 'ghc-8\.10\.8'`
+6. run `cabal run ghcup-gen -- check             -f ghcup-<yaml-ver>.yaml`
+7. run `cabal run ghcup-gen -- check-tarballs    -f ghcup-<yaml-ver>.yaml -u 'ghc-8\.10\.8'`
+8. run `cabal run ghcup-gen -- generate-hls-ghcs -f ghcup-<yaml-ver>.yaml --format json -o hls-metadata-0.0.1.json`
+9. run `cabal run ghcup-gen -- generate-table    -f ghcup-<yaml-ver>.yaml --stdout` and adjust [docs/install](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/docs/install.md) tables
+
+### During a pull request
+
+* make sure to always add new versions to both `ghcup-A.B.C.yaml` and `ghcup-vanilla-A.B.C.yaml`
+* make sure to run the bindist action to check tool installation on all platforms: https://github.com/haskell/ghcup-metadata/actions/workflows/bindists.yaml
+  - this is a manual pipeline
+  - set the appropriate parameters
+* make sure to sign the yaml files you edited, e.g.: `gpg --detach-sign -u <your-email> ghcup-0.0.7.yaml` or ask a GHCup developer to sign
+  - PGP pubkeys need to be cross-signed by the GHCup team
+  - they need to be added to the CI: https://github.com/haskell/ghcup-metadata/blob/develop/.github/workflows/sigs
+  - and need to be documented on the homepage
+    * https://github.com/haskell/ghcup-hs/blob/master/docs/guide.md#gpg-verification
+	* https://github.com/haskell/ghcup-hs/blob/master/docs/install.md#unix
+
+### Understanding tags
+
+Tags are documented [here](https://github.com/haskell/ghcup-hs/blob/master/lib/GHCup/Types.hs). Search for `data Tag`.
+Some tags are unique. Uniqueness is checked by `cabal run ghcup-gen -- check -f ghcup-<yaml-ver>.yaml`.
+
+If you want to check prereleases, do: `cabal run ghcup-gen -- check -f ghcup-prereleases-<yaml-ver>.yaml --channel=prerelease`

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
